or caustic soda.
-Direct vibration, shock or direct drop of water.
- Influence from power transmission lines, high voltage equipment, power cables, power equipment,
radio transmitters,or any other equipment that would generate high switching surges.(100mm or more)

Static electricity
- Do not touch connector pins directly to prevent static electricity from causing damage.
- Always rid yourself of any static electricity before handling this product.

Power supplies
-Twist the wires of the power supply.
-The unit has sufficient noise immunity against the noise generated on the power line.
However, it is recommended to take measures for reducing noise such as using a isolating transformer
before supplying the power.
-Allocate an independent wiring for each power supplying line, input/output device and operating device.
-If using a power supply without a protective circuit, power should be supplied through a protective
element such as a fuse.
-Be sure to supply power to a control and an expansion units from a single power supply.
Turning on/off of the power of all the units must be conducted simultaneously.

Power supply sequence

In order to protect the power supply sequence, make sure to turn off the control unit before the
input/output power supply. If the input/output power supply is turned off before the control unit, or if the
control unit is not shut off momentarily, the controller detects change of input level, and might conduct an
unexpected operation

Before turning on the power

When turning on the power for the first time, be sure to take the precautions given below.
-When performing installation, check to make sure that there are no scraps of wiring,
particularly conductive fragments, adhering to the unit.
-Verify that the power supply wiring, I/O wiring, and power supply voltage are all correct.
-Sufficiently tighten the installation screws and terminal screws.
-Set the mode selector to PROG. Mode.

v
Before entering a program
-Be sure to perform a program clear operation before entering a program.
-For information on the operating procedure, refer to the manuals of tool software.
(Tool software: FPWIN Pro, FPWIN GR)

Request concerning program storage

To prevent the accidental loss of programs, the user should consider the following measures.
-Drafting of documents
To avoid accidentally losing programs, destroying files, or overwriting the contents of a file,
documents should be printed out and then saved.
-Specifying the password carefully
The password setting is designed to avoid programs being accidentally overwritten. If the password is
forgotten, however, it will be impossible to overwrite the program even if you want to.
Also, if a possword is forcibly bypassed, the program is deleted. When specifying the password,
note it in the specifications manual or in another safe location in case it is forgotten at some point.

Battery
Do not install the battery when it is not used.
There is a possibility of leak if the battery remains discharged.

When Changing Ladder Program from 12k Type to 32k Type
It is necessary to convert the program to change the ladder program that is used for the FPΣ 12k
type to the one for FPΣ 32k type.

Program Conversion
When the FPWIN GR is used to change the model, the system register is automatically initialized.
If the setting value has been changed from the default value, note it down before the program conversion.

Number of points of internal relay for the 32k type is different from the 12k type.
The hold-type areas differ (automatic backup areas when the power supply was cut off) as the figure
shown below.
When the hold-type area in the internal relay is used, the program for that part should be converted.
(As the number of points for the counter, timer, DT and special DT is the same for the 12k type and 32k
type, the program conversion is not necessary.)

x
Procedure of Program Conversion
1. Retrieve a program to be converted with FPWIN GR.

2. Select “Option” → “PLC

Configuration” in the menubar.
Note down the setting value for the
system registers.

3. Select “Tool” → “Change PLC Type”.

Select “FPSIGMA 32K” and click “OK” button.

4. A message “System register formatted.” is indicated.

Click “OK” button.

5. Select “Option” → “PLC Configuration”.

Input the values noted down in procedure
2.

Note) When the battery is not used, the

system register No. 7 “Hold type area
starting word address for internal relay”
should be set to “248” that is the default
value for the FPΣ 32k type.

6. For the program using the hold-type area in the internal relay (R900 to R97F and WR90 to WR97), the
device should be changed to the hold-type area for the FPΣ 32k type (R2480 to R255F and WR248 to
WR255).
Select “Edit” → “Change Device”.

Click the buttons of “Source” and “Destination” to

select “R” and “WR” from the pulldown menu, and
change the values.

xi
How to change an existing program
It is an easy method for chaging an existing program by partially adding a program without modifying the
exsiting program.
(When a programmable display is connected, it is not necessary to change the R and WR that are
referred for the switches and data parts in the programmable display.)

1. At the begnning of a program

Data in the hold-type area is transferred to the

existing area only once when the power supply
turns on.

2. At the end of a program

Data in the hold-type area is always transferred

to the existing area.

<Explanation of the program>

Transfers the contents stored in the hold-type area (WR248 to WR255) to the existing hold-type area
WR90 to WR97 when the power supply turns on, and returns the previous state before the power
supply turns off (because the area WR90 to WR97 cannot be held without a battery on V3).
After returning to the previous state that is the one before the power supply turns off, always transfers
the WR operated during the scan or the information of R input from the programmabld display (WR90
to WR97) to the hold-type area (WR248 to WR255). And prepares for holding data when the power
supply turns off.

Chapter 1
Functions and Restrictions of the Unit
1.1 Features and Functions of the Unit
Powerful control capabilities
All of the functions of a mid-scale PLC are packed into the compact body size of the 32-pont type FP0. A
program capacity of 12k steps or 32k steps is provided as a standard feature, so you never have to
worry about how much memory is left as you’re programming. In addition, 32k words are reserved for
data registers, so large volumes of data can be compiled and multiple operations can be processed
without running out of memory.

A full range of communication functions

Using the Tool port (RS232C) provided as a standard feature on the main unit, communication can be
carried out with a display panel or computer. Additionally, communication cassettes with RS232C and
RS485 interfaces are available as an option. Installing a 2-channel RS232C type communication
cassette in the FPΣ makes it possible to connect two devices with RS232C port. A full lineup of
communication functions means you can also work with 1:N communication (up to 99 units) and
PC(PLC) link function (up to 16 units).

Controlling two devices with RS232C port with one FPΣ

When using the 2-channel RS232C type communication cassette

An analog potentionmeter (volume dial) is provided as a standard feature. This can be used in
applications such as analog timers, without using the programming tools. An analog unit is also available
as the intelligent unit.

Type with thermister input function

For the units of which part numbers or product numbers end in “TM”, the leader line which enables the
thermister input is equipped instead of an analog potetionmeter. The change of the resistance value of
the thermister can be taken in as an analog value.
(The thermister of which resistance value is from 200 to 75 kΩ can be used.)

Calender timer function can be added

Optional backup battery enables the calender timer function.

1-3
Positioning control supported through high-speed counter and pulse output
A high-speed counter and pulse output functions are provided as standard features. The pulse output
function supports frequencies of up to 100kHz, enabling positioning control using a stepping motor or
servo motor.

Measurement using high-speed counter supported

Increment input mode, decrement input mode, 2-phase input mode, individual input mode, and direction
discrimination mode are supported.

Positioning control based on pulse output supported

Pulse/direction and clockwise/counter –clockwise output are supported.

Heater control based on PWM output function supported

The pulse output at any duty ratio can be picked up with special instruction.

2.4 Analog Potentiometer

2.4.1 Overview of Analog Potentiometer

The FPΣ is equipped with two analog potentiometers as a standard feature. Turning the potentiometers
changes the values of the special data registers DT90040 and DT90041 within a range of K0 to K1000.
Using this function makes it possible to change the internal set values in the PLC without using the
programming tool, so this can be used, for example, with analog clocks, to change the set value
externally by turning the potentiometer.

Applicable special data register

Symbol Potentiometer No. Special data register Range of change
V0 Volume 0 DT90040
K0 to K1000
V1 Volume 1 DT90041

2.4.2 Example Showing How to Use Analog Potentiometer

The FPΣ is provided with special data registers, in which the values in the registers change in response
to the analog potentiometers being moved. If the values of these registers are sent to the clock setting
value area, a clock can be created that allows the time to be set using the potentiometer.

Example: Writing of the clock setting value

The value of the special data register (DT90040) that corresponds to the analog potentiometer V0 is sent
to the setting value area (SV0) of TMX0 to set the time for the clock.

2-13
2.5 Thermister Input (Only for TM type)

2.5.1 Overview of Thermister Input

The control units of which part and product numbers end in “TM” is quipped with the leader lines which
enable the thermister input instead of the analog potentiometer. The change in the termister’s resistance
values can be loaded as analog values by connecting the thermister with these leader lines.

Mechanism for loading thermister input

 Loads the change in the resistance values of the thermister connected externally as the change in
voltage, and then loads it as digital values by the AD converter in which a microcomputer is built.
 The values converted to digital values are reflected in the special data registers (DT90040 or
DT90041) and can be read in the user’s program.

<Block diagram>

Non-isolated between the FP thermister input unit

and the power supply connector (24V).
The red leader line is connected with the 3.3V power
supply and the black is connected with the Vin.

Total precision
Total precision
= (Total precision of AD converter in which microcomputer is built: ±5LSBNote))+(Precision of thermister)

Note) ±5LSB means there is a margin of error of ±5LSB for the values (0 to 1000) converted with AD
converter.

Thermister resistance values and digital conversion values

 Use the following formula for conversion of thermister resistance values and digital conversion values.
 Digital conversion values changes within a range of K0 to K1000.

Electronics Co., Ltd. 4300 K +100 to +200 °C
5133 K +150 to +300 °C

Note:
• The length of the wiring between the FPΣ control unit and the thermister should be less than 10m.
• A thin wire (AWG28, length: 150 mm) is used for the leader line. Connect and bundle the wire without
any stress.
• It is recommended to mount parts such as condensers externally if the converted value is unstable.

No values have been set in the default settings, so the programming tool or another means must be
used to specify the values.
As a day of the week is not automatially set on FPWIN GR, fix what day is set to 00, and set
each value for 00 to 06.

2.6.3 Example Showing the Clock/Calendar being Used

Sample program for fixed schedule and automatic start
In the example shown here, the clock/calendar function is used to output the (Y0) signal for one second,
at 8:30 a.m. every day.
Here, the “Hour/minute” data stored in the special data register DT90053 is used to output the signal at
the appointed time.

The hour data is stored in the upper 8 bits of DT90053 and the minute data in the lower 8 bits, in the
BCD format. This hour and minute data is compared with the appointed time (BCD), and the R900B
(=flag) special internal relay is used to detect whether or not it matches the appointed time.

5.2 Wiring of Power Supply

5.2.1 Wiring of Power Supply

Power supply wiring for the unit

Use the power supply cable (Product No.:AFPG805) that comes with the unit to connect the power
supply.
- Brown: 24V DC
- Blue: 0V
- Green: Function earth

Power supply wire

To minimize adverse effects from noise, twist the brown and blue wires of the power supply cable.

Power supply type

• To protect the system against erroneous voltage from the power supply line, use an insulated power
supply with an internal protective circuit.
• The regulator on the unit is a non-insulated type.
• If using a power supply device without an internal protective circuit, always make sure power is
supplied to the unit through a protective element such as a fuse.

Power supply voltage

Rated voltage 24V DC
Operating voltage range 21.6 to 26.4 V DC

5-8
Wiring system
Isolate the wiring systems to the control unit, input/output devices, and mechanical power apparatus.

Measures regarding power supply sequence (start up sequence)

• The power supply sequence should be set up so that power to the control unit is turned off before the
input/output power supplies.
• If the input/output power supplies are turned off before the power to the control unit, the control unit will
detect the input fluctuations and may begin an unscheduled operation.
• Be sure to supply power to a control unit and an expansion unit from the same power supply, and turn
the power on and off simultaneousl for both.

5-9
5.2.2 Grounding
In situations of excess noise
Under normal conditions, the inherent noise resistance is sufficient. However, in situations of excess
noise, ground the instrument to increase noise suppression.

Exclusive grounding
• The grounding connection should have a resistance of less than 100Ω.
• The point of grounding should be as close to the PLC unit as possible. The ground wire should be as
short as possible.
• If two devices share a single ground point, it may produce an adverse effect. Always use an exclusive
ground for each device.

Note:
Depending on the surroundings in which the equipment is used, grounding may cause problems.

[Example]
Since the power supply line of the FPΣ power supply connector is connected to the function earth
through a varistor, if there is an irregular potential between the power supply line and earth, the varistor
may be shorted.

Do not ground the FPΣ function earth terminal when grounding a plus (+) terminal of the power.
In some computers, the SG terminal of RS232C port and connector shieldingare connected. Also the
FPΣ tool port shielding is connected with the function earth terminal. Therefore, the GND terminal of FPΣ
and the function earth terminal are connected if the computer is connected. Especially when the FPΣ is
connected to a computer with a plus (+) terminal grounded, therefore, an FPΣ’s minus (-) terminal is
connected with the function earth terminal. As a result, short circuit occurs which may lead to the
breakage of FPΣ and its neighboring parts.

5.3 Wiring of Input and Output

5.3.1 Input Wiring

Connection of photoelectric sensor and proximity sensor
Relay output type NPN open collector output type

Voltage output type Two-wire output type

Precaution when using LED-equipped reed switch

When a LED is connected in series to an input
contact such as LED-equipped reed switch, make
sure that the on voltage applied to the PLC input
terminal is greater than 21.6V DC. In particular,
take care when connecting a number of switches
in series.

Precaution when using two-wire type sensor

If the input of PLC does not turn off because of
leakage current from the two-wire type sensor
“photoelectric sensor or proximity sensor”, the
use of a bleeder resistor is recommended, as
shown below.

The formula is based on an input impedance of

5.6kΩ. The input impedance varies depending on
the input terminal number.

5-11
Precaution when using LED-equipped limit switch
If the input of PLC does not turn off because of the
leakage current from the LED-equipped limit
switch, the use of a bleeder resistor is
recommended, as shown below.

5.3.2 Output Wiring
Protective circuit for inductive loads
 With an inductive load, a protective circuit should be installed in parallel with the load.
 When switching DC inductive loads with relay output type, be sure to connect a diod across the ends of
the load.

When using an AC inductive load

When using a DC inductive load

Precautions when using capacitive loads

When connecting loads with large in-rush currents, to minimize their effect, connect a protection circuit
as shown below.

About the short-circuit protective circuit

To prevent the output circuit from being damaged by a short-circuit or other electrical problems on the
output side, a transistor with short-circuit protection is provided.

5.3.3 Precautions Regarding Input and Output Wirings
• Be sure to select the thickness (dia.) of the input and output wires while taking into consideration the
required current capacity.
• Arrange the wiring so that the input and output wiring are separated, and these wirings are separated
from the power wiring, as much as possible. Do not route them through the same duct or wrap them up
together.
• Separate the input/output wires from the power and high voltage wires by at least 100mm/3.937 in.

5.6 Safety Measures

5.6.1 Safety Measures

Precautions regarding system design
In certain applications, malfunction may occur for the following reasons:

• Power on timing differences between the PLC system and input/output or mechanical power apparatus.
• Response time lag when a momentary power drop occurs.
• Abnormality in the PLC unit, external power supply, or other devices.

In order to prevent a malfunction resulting in system shutdown choose the adequate safety measures
listed in the following:

Interlock circuit
When a motor clockwise/counter-clockwise operation is controlled, provide an interlock circuit externally.

Emergency stop circuit

Provide an emergency stop circuit to the PLC externally to turn off the power supply of the output device.

Start up sequence
The PLC should be operated after all of the outside devices are energized. To keep this sequence, the
following measures are recommended:
• Turn on the PLC with the mode selector set to the PROG. mode, and then switch to the RUN mode.
• Program the PLC so as to disregard the inputs and outputs until the outside devices are energized.

Note) In case of stopping the operation of the PLC also, have the input/output devices turned off after
the PLC has stopped operating.

Grounding
When installing the PLC next to devices that generate high voltages from switching, such as inverters,
do not ground them together. Use an exclusive ground for each device.

5.6.2 Momentary Power Failures

Operation of momentary power failures
If the duration of the power failure is less than 3 ms, the FPΣ continues to operate. If the power is off for
3 ms or longer, operation changes depending on the combination of units, the power supply voltage, and
other factors. (In some cases, operation may be the same as that for a power supply reset.)

5-19
5.6.3 Protection of Power Supply and Output Sections
Power supply
An insulated power supply with an internal protective circuit should be used. The power supply for the
control unit operation is a non-insulated circuit, so if an incorrect voltage is directly applied, the internal
circuit may be damaged or destroyed. If using a power supply without a protective circuit, power should
be supplied through a protective element such as a fuse.

Protection of output
If current exceeding the rated control capacity is being supplied in the form of a motor lock current or a
coil shorting in an electromagnetic device, a protective element such as a fuse should be attached
externally.

5.7.2 Settings of Battery Error Alarm and Hold Area
Setting of the battery error alarm
- Setting the battery error alarm enables you to monitor the remaining backup battery level. By default,
the battery error alarm is set to off in the system register settings. For using the battery, check the box
of the system register No.4 "Alarm Battery Error" of the control unit.

Settings of Hold area/Non-hold area

- The settings of the operation memory area such as data regiters and system registers No.6 to No.14
are necessary.

Note:
- When "Battery Error Alarm" is not set, the ERR.LED will not flash even if a battery error is detected.
Note that data may be lost as the result of the battery shutoff.
- The setting of the system registers Nos. 6 to 14 are effective only when the backup battery is installed.
- Without the battery, use at the default settings. If changing the settings, the “Hold/Non-hold” operation
becomes unstable.

5-22
5.7.3 Replacement of Backup Battery
The procedure for replacing the backup battery is as follows.

Procedure
1. Supply power to the control unit for more than one minute.
Charge the built-in capacitor to retain the contents of the memory during the replacement of the battery.
2. Turn off the power supply.
Remove the battery cover using a tool such as a screwdriver.

4. Remove the used battery.

5. Install a new battery within two minutes after turning off the power.
Connect the connector, and place the battery between two tabs.

6. Install the expansion cover.

Note:
- If the power is not sufficiently supplied or it takes too much time to replace the battery, retained memory
data may be lost.

5-23
5.7.4 Lifetime and Time for Replacement of Backup Battery
Battery lifetime
Suggested Typical lifetime
Type of control unit Battery lifetime
replacement interval in actual use
Approx. 2.3 years
FPΣ control unit 220 days or more 1 year
(at 25 °C)
Note1) The battery lifetime is the value when no power at all is supplied.
Note2) Note that the lifetime in actual use may be shorter than the typical lifetime depending on the use
conditions.
Note3) The battery is used for the battery detection circuit even when power is supplied. The lifetime is
about twice as long as that when no power is supplied.

Detection of battery error and time for replacement

- Special internal relays R9005 and R9006 will go on if the battery voltage drops. Creaet a program to
announce errors to the outside as necessary. Two seconds after starting supplying power, the battery
voltage is checked. Therefore, an error is not announced in the first scan.
- When the system register No.4 "Battery Error Alarm" is enabled, the ERR.LED of the control unit will
flash.
- Although data will be retained for about a week after the detection of battery error without power, the
battery should be replaced as soon as possible.

Note:
- if a week has passed without power after the special internal relays R9005 and R9006 turned on or the
ERR.LED flashed, retained memory data may be lost.
- Regardless of how much time has passed after the detection of battery error, supply power to the
control unit for more than one minute when replacing the battery.
- Special internal relays R9005 and R9006 will be on when a batttery error is detected regardless of the
setting of system regisnter No.4.

High-speed counter, Pulse Output and
PWM Output functions
6.1 Overview of Each Functions

6.1.1 Three Functions that Use Built-in High-speed Counter

There are three functions available when using the high-speed counter built into the FPΣ.

High-speed counter function

The high-speed counter function counts external
inputs such as those from sensors or encoders.
When the count reaches the target value, this
function turns on/off the desired output.

Pulse output function

Combined with a commercially available motor
driver, the function enables positioning control.
With the exclusive instruction, you can perform
trapezoidal control, home return, and JOG
operation.

PWM output function

By using the exclusive instruction, the PWM output
function enables a pulse output of the desired duty
ratio.

6-2
6.1.2 Performance of Built-in High-speed Counter
Number of Channel
• There are four channels for the built-in high-speed counter
• The channel number allocated for the high-speed counter will change depending on the function being
used.

Counting range
• K-2, 147, 483, 648 to K+2, 147, 483, 647 (Coded 32-bit binary)
• The built-in high-speed counter is a ring counter. Consequently, if the counted value exceeds the
maximum value, it returns to the minimum value. Similarly, if the counted value drops below the
minimum value, it goes back to the maximum value and continues counting from there.

Note:
When the linear interpolation instruction F175 or the circular interpolation instruction F176 is used, the
value for the target value or the amount of travel should be set so that it is within the range indicated
below.
-8,388,608 to +8,388,607 (Coded 24-bit binary)
The F175 and F176 instructions can be used only with the C32T2, C28P2, C32T2H and C28P2H control
units.

Restrictions on I/O allocations

• The inputs and outputs allocated to the various functions listed in the table in the previous section
“6.2.1” cannot be allocated to more than one function.
• Except for the examples noted below, inputs and outputs that have been allocated to the various
functions cannot be allocated as normal inputs and outputs.

Example 1:
If no reset input is used in the high-speed counter function, X2 and X5 can be as normal inputs.
Example 2:
If no output is used to clear the differential counter in the pulse output function, Y2 and Y5 can be used
as normal outputs.

Restrictions on the execution of related instructions (F166 to F176)

• If an instruction related to the high-speed counter “F166 to F176” is executed, the control flag (special
internal relay: R903A to R903D) corresponding to the channel used turns on.

6-7
• Please be aware that the control flag “in progress” may change while a scan is being carried out. To
prevent multiple read access to this special internal relay, you should generate a copy of it at the
beginning of the program.
• When the control flag for a channel turns on, another instruction using that same channel cannot be
executed.
• Executing circular interpolation control instruction F176 sets the circular interpolation in progress flag
(special internal relay: R904E), and that state is maintained until the target value is achieved. During
this time, other pulse output instructions (F171 to F176) cannot be executed.

6.3 High-speed Counter Function

6.3.1 Overview of High-speed Counter Function

• The high-speed counter function counts the input signals, and when the count reaches the target value,
turns on and off the desired output.
• To turn on an output when the target value is matched, use the target value match ON instruction F166
(HC1S). To turn off an output, use the target value match OFF instruction F167 (HC1R).
• Preset the output to be turned on and off with the SET/RET instruction.

Setting the system register

In order to use the high-speed counter function, it is necessary to set system register numbers nos. 400
and 401.

6.3.2 Input Modes and Count

Setting the system register

When using the pulse output function, set the channels corresponding to system registers 400 and 401
to “Do not use high-speed counter”.

6-18
6.4.2 Types of Pulse Output Method and Operation Modes
Clockwise/counter-clockwise output method
Control is carried out using two
pulses: a forward rotation pulse and a
reverse rotation pulse.

Pulse/direction output method (forward: OFF/reverse: ON)

Control is carried out using one pulse
output to specify the speed and
another to specify the direction of
rotation with on/off signals. In this
mode, forward rotation is carried out
when the rotation direction signal is
OFF.

Pulse/direction output method (forward: ON/reverse: OFF)

Control is carried out using one pulse
output to specify the speed and
another to specify the direction of
rotation with on/off signals. In this
mode, forward rotation is carried out
when the rotation direction signals is
ON.

by executing the pulse output instruction with the target value +1000, and the current position will be
1000.

Home return
• When executing the F171 (SPDH) instruction, the pulse is continuously output until the home input (X2
or X5) is enabled.
• To decelerate the movement when near the home position, designate a near home input and set bit 4
of special data register DT90052 to off → on → off.
• The deviation counter clear output can be output when home return has been completed.

JOG operation
• Pulses are output from the specified channel while the trigger for F172 (PLSH) instruction is in the ON
state. Also, the pulse output can be stopped when the specified target value is matched.
• The direction output and output frequency are specified by F172 (PLSH) instruction.

Flag movement when command running

Action when the execution conditions turn OFF

• Differing from other pulse output instructions, circular interpolation instruction F176 executes the
execution conditions as continually ON.
• Circular interpolation instruction F176 stops pulse output when the execution conditions turn OFF.

Note:
• Right when the execution condition turn off, positioning instructions F171 to F176, other than the
currently running instruction F176, cannot be started up when the target value has not been reached.
• When restarting, use pulse output control instruction F0, below, to reset the pulse output instruction.
This operation resets the control flag for circular interpolation (R904E).

About composite speed setting

• The maximum composite speed setting is 20 kHz.

Use the range of the formula given below as a guide when setting the composite speed.

Fv (Hz) ≦ r (pulse) × 10/t (ms)

Fv : Composite speed (Hz)

R : Radius (pulse)
t : Scan time (ms)
Example: Radius r: 1000 (pulse), Scan time 5ms
Fv ≦ 1000 (p) × 10/5 (ms) = 2000 Hz

Note:
• The instruction calculates the component speed at each scan. Therefore, accuracy may be degraded if
the scan time exceeds 10 ms. If this should happen, execute circular interpolation instruction F176
using the periodical interrupt function with an interrupt time of around 0.5 ms.

6-42
Restrictions on positioning data setting
• Designate settings for the target position, pass position and center position so they are within the
following range.
Allowable range: -8,388,608 to +8,388,608
• When using in combination with other positioning instructions like F171, designate so the target value
is within the above range, even in those instructions.

Home return operation (Minus direction)
When XA turns on, the pulse is output from CCW output Y1 of the specified channel CH0 and CCW
output Y4 of the specified channel CH2, and the return to home begins.
In CH0, when X3 turns on, deceleration begins, and when X2 turns on, home return is completed. After
the return to home is completed, the elapsed value areas DT90044 and DT90045 are cleared to 0.
In CH2, when X6 turns on, deceleration begins, and when X5 turns on, home return is completed. After
the return to home is completed, the elapsed value areas DT90200 and DT90201 are cleared to 0.
When the operations in both CHs is completed, the return to home completes.

Communication Cassette
7.1 Functions and Types

7.1.1 Functions of Communication Cassette

With the optional communication cassette, the FPΣ offers three different communication modes:
computer link, general-purpose serial communication, and PC(PLC) link.

Computer link
• The computer link function is to communicate between a computer and PLCs or between PLC and
external devices connected. A proprietary MEWNET protocol called MEWTOCOL-COM is used for
communicating with the computer link. MEWTOCOL-COM is also used for the communication between
the tool software such as FPWIN-GR and the PLC.
• There are a MEWTOCOL master function and a MEWTOCOL slave function for the computer link. The
side that issues commands is called master, and the side that receives the commands, executes the
process and sends back responses is called slave.

Note:
It is necessary to set the system register of the communication port to the computer link for using this
function.
1. Only the slave function is available for the FPΣ 12k type.
2. Both the master and slave functions are available for the FPΣ 32k type, however, the master function
is not available for the TOOL port.

MEWTOCOL master function (32k type only)

• This function is to carry out the communication on the master side (side 0that issues commands) of the
computer link. It is executed with the PLC’s instruction F145(SEND) or F146(RECV). It is not necessary
to write the response process as a ladder, so the program is easier than the general-purpose
communication function.

The 1:1 or 1:N communication is available between our devices equipped with the computer link function
and the MEWTOCOL-COM.
[Our devices (e.g.)] : PLC, IPD, temperature control unit, eco-power meter

For the MEWTOCOL master function, communication is possible with COM1 port and COM2 port of the
32k type only. Do not execute the F145 (SEND) nor F146 (RECV) instructions when the unti is used as a
slave unit.

7-2
MEWTOCOL slave function
• This function is to receive commands from the computer link, execute the process and send back the
results. Any special ladder program is not necessary to use this function. (Set the communication
conditions in the system registers.) It enables the 1:1 or 1:N communication with a master computer or
PLC.
• The program for the computer side must be written in BASIC or C language according to the
MEWTOCOL-COM. MEWTOCOL-COM contains the commands used to monitor and control PLC
operation.

General-purpose serial communication

• With general-purpose serial communication, data can be sent back and forth between an image
processing device connected to the COM. port and an external device such as a bar code reader.
• Reading and writing of data is done using a ladder program in the FPΣ, while reading and writing of
data from an external device connected to the COM. port is handled through the FPΣ data registers.

7-3
PC(PLC) link
 In a PC(PLC) link, data is shared with all PLCs connected via MEWNET using dedicated internal relays
called link relays (L) and data registers called link registers (LD).
 If the link relay contact for one PLC goes on, the same link relay also goes on in each of the other
PLCs connected to the network. Likewise, if the contents of a link register are rewritten in one PLC, the
change is made in the same link register of each of the other PLCs connected to the network.
 The status of the link relays and link registers in any one PLC is fed back to all of the other PLCs
connected to the network, so control of data that needs to be consistent throughout the network, such
as target production values and type codes, can easily be implemented to coordinate the data, and the
data of all units are updated at the same time.

- Link relay
In the figure below, when link relay L0 of the master station (no.1) turns on, this signal is converted by
the programs of the other stations, and Y0 of the other stations is activated.

- Link register
In the figure below, if a constant of 100 is written to LD0 of the master station (no.1), the contents of LD0
in the other stations are also changed to a constant of 100.

7-4
MODBUS RTU (32k type only)
Function overview
• The MODBUS RTU protocol enables the communication between the FPΣ and other devices (including
our FP-e, Programmable display GT series and KT temperature control unit).
• Enables to have conversations if the master unit sends instructions (command messages) to slave
units and the slave units respond (response messages) according to the instructions.
• Enabels the communication between the devices of max. 99 units as the master function and slave
function is equipped.

About MODBUS RTU

• The MODBUS RTU communication is a function for the master unit to read and write the data in slave
units communicating between them.
• There are ASCI mode and RTU (binary) mode in the MODBUS protocol, however, the FPΣ is
supported with the RTU (binary) mode only.

Master function
Writing and reading data for various slaves is available using the F145 (SEND) and F146 (RECV)
instructions.
Individual access to each slave and the global transmission is possible.

Slave function
If the slave units receive a command message from the master unit, they send back the response
message corresponding to the content.
Do not execute the F145 (SEND) nor F146 (RECV) instructions when the unti is used as a slave unit.

7-5

Note1) When connecting a commercially available device that has an RS485 interface, please confirm
operation using the actual device. In some cases, the number of units, transmission distance,
and baud rate vary depending on the connected device.

7-10
Note2) The values for the transmission distance, baud rate and number of units should be
within the values noted in the graph below.

When using a baud rate of 2400 bps to 38400 bps, you can set up to a maximum of
99 units (stations) and maximum transmission distance of 1200 m.

Note3) Only 9600 bps or 19200 bps can be specified when the C-NET adapter is connected with the
RS485 interface.
Note4) The start code and end code can be used only in the general-purpose serial communication
mode.
Note5) The converter SI-35 manufactured by Lineeye Co., Ltd is recommendable for the RS485 at the
computer side. Adjust the response time for the FP-X by the SYS1 instruction if necessary.
Note6)Regarding the setting of unit numbers:
When the unit number setting switch is “0”, the system register is effective.
When the unit number setting switch is other than “0”, the unit number setting switch is effective,
and the unit number setting of the system register is ignored.
(Max. 31 units can be specified with the unit number setting switch.) (When the setting is specified
with the unit number setting switch, the COM1 port and the COM2 port has the same unit
number.
Note7)Connect the “−“ terminal and the “+” terminal with a lead wire to make the termination resistance
of the AFPG803 effective.
The termination resistance of the AFPG806 is specified by the dip switch in the communication
cassette.
There is no termination resistance at the RS232C port.
Note8) The RS485 port of the AFPG806 is either 19200 bps or 115200 bps only.
Also the baud rate must be identically set by the system register and the dip switch in the
communication cassette. The baud rate for the PC(PLC) link mode is fixed at 115200 bps.
The baud rate for the RS232C port of the AFPG806 can be set by the system register only.
Note9) The MEWTOCOL master function, MODBUS RTU master function and general-purpose serial
communication function at the TOOL port is available only for the FPΣ 32k type.

7-11
7.2.1 Precaution When Using RS485 Port
FPG-COM3 (AFPG803), FPG-COM4 (AFPG806)
SYS1 instruction is available for FPΣ, which enables to change the time after receiving a command until
a response is returned.
With the converter SI-35 manufactured by Lineeye Co., Ltd, adjust the response time by this instruction if
necessary.

SYS1 instruction: This is to delay a response for [n] scan time to be specified.

Example:

When R0 turns on, the response of COM1 port (RS485 port) delays for two scans. If the scan time is
500µs, it delays for 1 ms.

Reference: <FP series Programming manual>

The RS485 port of AFPG806 (COM4) occupies the communication line for a given time after transmitting
data. No transmission is available during this period.
When data is transmitted from FPΣ via the RS485 communication of AFPG806 (COM4), start the
transmission of the data to FPΣ after the time mentioned blow passes at a receiver.

7-12
Following adjustments are required depending on the types of connected equipment.
1. With FPΣ (when the connected equipment are also the combination of FPΣ and AFPG806)
• When PC(PLC) link mode: Adjustment is not required.
• When general communication mode: Adjust timing by ladder program.
• When computer link mode: Adjust timing by SYS1 instruction.

2. With other PLC

• When PC(PLC) link mode: Not used.
• When general communication mode: Adjust timing by ladder program.

3. With computer
• Adjust timing by wait instruction system.

4. With other equipment’s

• Confirm the time after receiving data until a transmission starts with makers.
• KT temperature controller and inverters (VF-7E and VF-8X) can be used without any adjustment, as
the time taken up to a response is more than 1 ms.
• GT series indicator cannot be used.
• With GV series indicator, set the transmission delay time (communication parameter) to 1 ms or more.

7.4 Communication Function 1: Computer Link

7.4.1 Computer Link

Overview

Computer link
• The computer link function is to communicate between a computer and PLCs or between PLC and
external devices connected. A proprietary MEWNET protocol called MEWTOCOL-COM is used for
communicating with the computer link. MEWTOCOL-COM is also used for the communication between
the tool software such as FPWIN-GR and the PLC.
• There are a MEWTOCOL master function and a MEWTOCOL slave function for the computer link. The
side that issues commands is called master, and the side that receives the commands, executes the
process and sends back responses is called slave.
•

Note:
It is necessary to set the system register of the communication port to the computer link for using this
function.
1. Only the slave function is available for the FPΣ 12k type.
2. Both the master and slave functions are available for the FPΣ 32k type, however, the master function
is not available for the TOOL port.

7-18
MEWTOCOL master function (32k type only)
• This function is to carry out the communication on the master side (side 0that issues commands) of the
computer link. It is executed with the PLC’s instruction F145(SEND) or F146(RECV). It is not necessary
to write the response process as a ladder, so the program is easier than the general-purpose
communication function.

The 1:1 or 1:N communication is available between our devices equipped with the computer link function
and the MEWTOCOL-COM.
[Our devices (e.g.)] : PLC, IPD, temperature control unit, eco-power meter

For the MEWTOCOL master function, communication is possible with the 32k-type COM1 and COM2
ports only. Do not execute the F145 (SEND) nor F146 (RECV) instructions when the unti is used as a
slave unit.

MEWTOCOL slave function

• This function is to receive commands from the computer link, execute the process and send back the
results. Any special ladder program is not necessary to use this function. (Set the communication
conditions in the system registers.) It enables the 1:1 or 1:N communication with a master computer or
PLC.
• The program for the computer side must be written in BASIC or C language according to the
MEWTOCOL-COM. MEWTOCOL-COM contains the commands used to monitor and control PLC
operation.

7-19
Outline of operation when using computer link (MEWTOCOL slave)
Command and response
• Instructions issued by the computer to the PLC are called commands. Messages sent back to the
computer from the PLC are called responses. When the PLC receives a command, it processes the
command regardless of the sequence program, and sends a response back to the computer.

MEWTOCOL-COM sketch
• Communication is carried out in a conversational format, based on the MEWTOCOL-COM
communication procedures.
• Data is sent in ASCII format.
• The computer has the first right of transmission. The right of transmission shifts back and forth
between the computer and the PLC each time a message is sent.

7-20
Format of command and response
Command message
All command-related items should be noted in the text segment. The unit number must be specified
before sending the command.

1. Header (start code)

Commands must always have a “%” (ASCII code: H25) or a “<” (ASCII code: H3C) at the beginning of a
message.

2. Unit number
The unit number of the PLC to which you want to send the command must be specified. In 1:1
communication, the unit number “01” (ASCII code: H3031) should be specified.

3. Text
The content differs depending on the command. The content should be noted in all upper-case
characters, following the fixed formula for the particular command.

4. Check code
BCC (block check code) for error detection using horizontal parity. The BCC should be created so that it
targets all of the text data from the header to the last text character. The BCC starts from the header and
checks each character in sequence, using the exclusive OR operation, and replaces the final result with
character text. It is normally part of the calculation program and is created automatically.
The parity check can be skipped by entering “* *” (ASCII code: H2A2A) instead of the BCC.

5. Terminator (end code)

Messages must always end with a “CR” (ASCII code: H0D).

7-21
 Note:
• The method for writing text segments in the message varies depending on the type of command.
• If there is a large number of characters to be written, they may be divided and sent as several
commands. If there is a large number of characters in the value that was loaded, they may be divided
and several responses sent.

Key Point:
• With the FPΣ, an expansion header “<” is supported to send single frames of up to 2048 characters as
well as general “%”.
Type of header No. of characters that can be sent in 1 frame
% Max. 118 characters
< Max. 2048 characters

Response message
The PLC that received the command in the example above sends the processing results to the computer.

1. Header (start code)

A “%” (ASCII code: H25) or “<” (ASCII code: H3C) must be at the beginning of a message. The response
must start with the same header that was at the beginning of the command.

2. Unit number
The unit number of the PLC that processed the command is stored here.

3. Text
The content of this varies depending on the type of command. The value should be read based on the
content. If the processing is not completed successfully, an error code will be stored here, so that the
content of the error can be checked.

7-22
4. Check code
BCC (block check code) for error detection using horizontal parity. The BCC starts from the header and
checks each character in sequence, using the exclusive OR operation, and replaces the final result with
character text.

5. Terminator (end code)

There is always a “CR” (ASCII code: H0D) at the end of the message.

Note:
• If no response is returned, the communication format may not be correct, or the command may not
have arrived at the PLC, or the PLC may not be functioning. Check to make sure all of the
communication specifications (e.g. baud rate, data length, and parity) match between the computer and
the PLC.
• If the response contains an “!” instead of a “$”, the command was not processed successfully. The
response will contain a communication error code. Check the meaning of the error code.
• Unit number and command name are always identical in a command and its corresponding response
(see below). This makes the correspondence between a command and a response clear.

Programming
• For a computer link, a program should be created that allows command messages to be sent and
response messages to be received on the computer side. The PLC automatically sends back a
response to a command. No communication program is required on the PLC side.
• Also, if a software program such as PCWAY is used on the computer side, PLC data can easily be
read and written without having to think about the MEWTOCOL-COM protocol

Connection to the computer <1:1 communication>
Overview
For a 1:1 computer link between the FPΣ and a computer, an RS232C cable is needed. Communication
is performed via commands from the computer and responses from the PLC.

7.4.3 1:N Communication (Computer Link)
Overview
For a 1:N computer link, the computer and the FPΣ are connected through a commercially available
RS232C-RS485 conversion adapter, and the respective PLCs are wired using an RS485 cable.
The computer and the PLC communicate via commands and responses: The computer sends a
command specifying the unit number, and the PLC with that unit number sends a response back to the
computer.

When data is transmitted from FPΣ via the RS485 communication of AFPG806 (COM4), start the
transmission of the data to FPΣ after the time mentioned blow passes at a receiver.
In case of 19200 bps: 1 ms In case of 115200 bps: 200µs

Note2) The RS485 port of the AFPG806 is either 19200 bps or 115200 bps only.
Also the baud rate must be identically set by the system register and the dip switch in the
communication cassette.
Note3) Setting the unit number setting switch to 0 makes the system register settings valid.
Note4) Connect the “−“ terminal and the “E” terminal with a lead wire to make the termination resistance
of the AFPG803 effective.
The termination resistance of the AFPG806 is specified by the dip switch located in the
communication cassette.

7-28
Setting of unit numbers
By default, the unit number for each communication port is set to 1 in the system register settings. There
is no need to change this for 1:1 communication, but if 1:N communication is used to connect multiple
PLCs to the transmission line (e.g. in a C-NET), the unit number must be specified so that the
destination of the command can be identified.
The unit number is specified either by using the unit number setting switch or the system register.

When the unit number setting switch is “0”, the system register is valid.
When the unit number setting switch is “other than 0”, the unit number setting switch is valid, and the unit
number setting of the system register is ignored. In this case, the same number is given to the port 1 and
port 2.

Note:
• Unit numbers set using the unit number setting switch are valid only for the communication port of the
communication cassette. Tool port unit numbers should be set using the system register.

7.5 Communication Function: General-purpose Serial
Communication

7.5.1 General-purpose Serial Communication

Overview
• In general-purpose serial communication, data is sent and received over the COM ports to and from an
external device such as an image processing device or a bar code reader.
• Data is read from and written to an external device connected to the COM port by means of an FPΣ
program and the FPΣ data registers.

Outline of operation
To send data to and receive it from an external device using the general-purpose serial communication
function, the data transmission and data reception functions described below are used. The F159
(MTRN) instruction and the “reception done” flag are used in these operations, to transfer data between
the FPΣ and an external device.

Sending data
Data to be transmitted from the PLC is stored in the data register used as the send buffer (DT). When
F159 (MTRN) is executed, the data is output from the COM port.
• The terminator specified in the system
register is automatically added to the data
that has been sent.
• The maximum volume of data that can be
sent is 2048 bytes.

7-35
Receiving data
Data received from the COM port is stored in the receive buffer specified in the system register, and the
“reception done” flag goes on. Data can be received whenever the “reception done” flag is off.

• When data is being received, the “reception

done” flag is controlled by the F159 (MTRN)
instruction.
• No terminator is included in the stored data.
• The maximum volume of data that can be
received is 4096 bytes.

7-36
Setting Baud rate, communication format
By default, the COM port is set to “Computer link”. System register settings should be entered for the
following items.
The settings for baud rate and communication format are made using the FPWIN GR programming tool.

data register area is defined as the receive buffer. To change this area, specify the starting address
using system register no. 416 (no. 418 for COM2 port) and the volume (number of words) using no. 417
(no. 419 for COM2 port). The receive buffer layout is shown below.

7-37
7.5.2 Communication with External Devices
Programming example of general-purpose serial communication
The F159 (MTRN) instruction is used to send and receive data via the specified COM port. F159 (MTRN)
is only used with the FPΣ. It is an updated version of F144 (TRNS) and allows multiple communication
ports to be accommodated.
F144 (TRNS) is not available with the FPΣ.

F159 (MTRN) instruction

Data is sent and received via the specified COM port .

Devices that can be specified for S: Only data registers (DT) can be specified as the send buffer.
Devices that can be specified for n: WX, WY, WR, WL, SV, EV, DT, LD, I (I0 to ID), K, H
Devices that can be specified for D: Only the K constants (only K1 and K2)

Transmission of data
The amount of data specified by n is sent to the external device from among the data stored in the data
table, starting with the area specified by S, through the COM port specified by D. Data can be sent with
the header and terminator automatically attached. A maximum of 2048 bytes can be sent. When the
above program is run, the eight bytes of data contained in DT101 to DT104 and stored in the send buffer
starting from DT100 are sent from COM1 port.

Reception of data
Reception of data is controlled by turning the “reception done” flags R9038/R9048 on and off. The
received data is stored in the receive buffe specified in the system register. Data can be received when
F159 (MTRN) turns the “reception done” flag off. When the reception of the data is completed (the
terminator is received), the “reception done” flag turns on, and subsequently, receiving data is prohibited.
To receive the next data, execute the F159 (MTRN) instruction and turn the “reception done” flag off to
clear the number of received bytes to 0. To receive data continuously without sending data, clear the
number of transmitted bytes to 0 (set “n” to “K0”), and then execute the F159 (MTRN) instruction.

7-38
Sending data to external devices
Communication with external devices is handled through the data registers.
Data to be output is stored in the data register used as the send buffer (DT), and when the F159 (MTRN)
instruction is executed, the data is output from the COM port.

Data table for transmission (send buffer)

Sample program for sending data

The following program transmits the characters “ABCDEFGH (Hex)” to an external device using COM1
port.

The program described above is executed in the following sequence.

1) “ABCDEFGH” is converted to an ASCII code and stored in a data register.
2) The data is sent from COM1 port using the F159 (MTRN) instruction.

Explanatory diagram

7-39
Explanation of data table
The data table for transmission starts at the data register specified in S.

• Use an F0 (MV) or F95 (ASC) instruction to write the data to be transmitted to the transmission data
storage area specified in S.

Transmission process
When the execution condition of the F159 (MTRN) instruction turns on and the “transmission done” flag
R9039/R9049 is on, operation is as follows:
1. N is preset in S. The “reception done” flag R9038/R9048 is turned off, and the reception data number
is cleared to 0.
2. The set data is transmitted in order from the lower-order byte in S+1 of the table.
• During transmission, the “transmission done” flag R9039/R9049 turns off.
• If system register 413 or 414 is set to header (start code) with STX, the header is automatically added
to the beginning of the data.
• The terminator (end code) specified in system register 413 or 414 is automatically added to the end of
the data.

3. When all of the specified quantity of data has been transmitted, the S value is cleared to 0 and the
“transmission done” flag R9039/R9049 turns on.

When you do not wish to add the terminator (end code) during transmissions:
• Specify the number of bytes to be transmitted using a negative number.
• If you also do not wish to add a terminator to received data, set system register 413 or 414 to
“Terminator - None”.

Programming example:
The following program transmits 8 bytes of data without adding the terminator.

Key Point:
• Do not include the terminator (end code) in the transmission data. The terminator is added
automatically.
• When “STX exist” is specified for the header (start code) in system register 413 or 414, do not add the
header to the transmission data. The header is added automatically.
• When using the 1-channel RS232C type communication cassette, transmission does not take place
until CS (Clear to Send) turns on. If you are not going to connect to the other device, connect to RS
(Request to Send).
• The maximum number of transmission bytes n is 2048.
• The contact numbers in parentheses refer to COM2 port.
7-40
Receiving data from external devices
Data input from the COM port is stored in the
receive buffer specified by the system register,
and the “reception done” flag goes on. If the
“reception done” flag is off, data can be received
at any time.

Data table for reception (receive buffer)

This is the state when the above program is executed.
• DT200 to DT204 are used as the receive
buffer. System register settings are as follows:
- System register 416: K20
- System register 417: K5

Sample program for receiving data

10-byte data received in the receive buffer through COM1 port are copied to DT0.

The program described above is executed in the following sequence.

1) Data is received from the RS232C device to the receive buffer.
2) The “reception done” contact R9038 (R9048) is turned on.
3) The received data is sent from the receive buffer to the area starting with data register DT0.
4) The F159 (MTRN) instruction is executed with no data to reset the buffer writing point and to turn off
the reception done” contact R9038 (R9048).
The system is now ready to receive the next data.
(The data in the receive buffer is not cleared.)

Note:
• Be aware that the “reception done” flag R9038 or R9048 changes even while a scan is in progress
(e.g., if the “reception done” flag is used multiple times as an input condition, there is a possibility of
different statuses existing within the same scan.) To prevent multiple read access to the special internal
relay you should generate a copy of it at the beginning of the program.

Explanatory diagram

7-41
Explanation of data table
Data sent from an external device connected to the RS232C port is stored in the data registers that have
been set as the receive buffer.
• Specify the data registers in system register 416 to
419.
• The number of bytes of data received is stored in the
starting address of the receive buffer. The initial value
is 0.
• Received data is stored in the received data storage
area in order from the lower -order byte.

Reception process
When the “reception done” flag R9038 (R9048) is off, operation takes place as follows when data is sent
from an external device. (The R9038 (R9048) flag is off during the first scan after RUN).
1. Incoming data is stored in order from the lower-order byte of the 2nd-word area of the receive buffer.
Header and terminator (start and end codes) are not stored.

2. When the terminator (end code) is received, the “reception done” flag R9038 (R9048) turns on.
Reception of any further data is prohibited.
3. When an F159 (MTRN) instruction is executed, the “reception done” flag R9038 (R9048) turns off, the
number of received bytes is cleared, and subsequent data is stored in order from the lower-order byte.
For repeated reception of data, perform the following steps:
1. Receive data
2. Reception done (R9038/R9048: on, reception prohibited)
3. Process received data
4. Execute F159 (MTRN) (R9038/R9048: off, reception possible)
5. Receive subsequent data

Prepare for reception

• The “reception done” flag R9038 (R9048) turns on when
data reception from the external device is completed.
Reception of any further data is prohibited.
• To receive subsequent data, you must execute the F159
(MTRN) instruction to turn off the “reception done” flag
R9038 (R9048).

Key Point:
• The contact numbers in parentheses refer to COM2 port.

7-42
Data to be sent/received with FPΣ
Remember the following when accessing data in the FPΣ send and receive buffers:
• If a header has been chosen in the communication format settings, the code STX (H02) will
automatically be added at the beginning of the data begin sent.
• The data without the Code STX at the reception is stored in the receive buffer, and the “reception
done” flag turns on when the terminator (end code) is received.
However, if the code STX is added in the middle of the data, the number of received byte is cleared to
0, and the data is stored from the beginning of the receive buffer.
• A terminator is automatically added to the end of the data being sent.
• There is no terminator on the data stored in the receive buffer.

Sending data:
Data written to the send buffer will be sent just as it is.

Example:
The data “12345” is transmitted as an ASCII code to a device with RS232C port.
1. Data sent using the F95 (ASC) instruction should be converted to ASCII code data.

2. If DT100 is being used as the send buffer, data will be stored in sequential order in the data registers
starting from the next register (DT101), in two-byte units consisting of the upper and the lower byte.

Receiving data:
The data of the receive area being read is ASCII code data.

Example:
The data “12345CR” is transmitted from a device with RS232C port.
• If DT200 is being used as the receive buffer, received data will be stored in the registers starting from
DT201, in sequential order of first the lower byte and then the upper byte.

7-43
Flag operation in serial communication
Header: No-STX, Terminator: CR
Receiving data:
The “reception done” flag, the “transmission done” flag, and the F159 (MTRN) instruction are related as
follows:

• For general-purpose serial communication, half-duplex transmission must be used.

• Reception is disabled when the “reception done” flag R9038 or R9048 is on.
• When F159 (MTRN) is executed, the number of bytes received is cleared, and the address (write
pointer) in the receive buffer is reset to the initial address.
• Also, when F159 (MTRN) is executed, the error flag R9037 or R9047, the “reception done” flag R9038
or R9048 and the “transmission done” flag R9039 or R9049 goes off.
• Duplex transmission is disabled while F159 (MTRN) is being executed. The “transmission done” flag
R9039 or R9049 must be observed.
• Reception continues even if the error flag R9037 turns on. To resume reception, execute the F159
(MTRN) instruction, which turns off the error flag.

Note:
• Be aware that the “reception done” flag R9038 or R9048 changes even while a scan is in progress
(e.g., if the “reception done” flag is used multiple times as an input condition, there is a possibility of
different statuses existing within the same scan.) To prevent multiple read access to the special internal
relay you should generate a copy of it at the beginning of the program.

Key Point:
• The contact numbers in parentheses refer to COM2 port.

7-44
Header: STX, Terminator: ETX
Receiving data:
The “reception done” flag, the “transmission done” flag, and the F159 (MTRN) instruction are related as
follows:

• The data is stored in the receive buffer in sequential order. When the header is received, the number of
bytes received is cleared, and the address (write pointer) in the receive buffer is reset to the initial
address.
• Reception is disabled while the “reception done” flag R9038 or R9048 is on.
• Also, When F159 (MTRN) is executed, the number of bytes received is cleared, and the address (write
pointer) in the receive buffer is reset to the initial address.
• If there are two headers, data following the second header overwrites the data in the receive buffer.
• The “reception done” flag R9038 or R9048 is turned off by the F159 (MTRN) instruction. Therefore, if
F159 (MTRN) is executed at the same time the terminator is received, the “reception done” flag will not
be detected.

7-45
Sending data:
The “reception done” flag, the “transmission done” flag, and the F159 (MTRN) instruction are related as
follows:

• Header (STX) and terminator (ETX) are automatically added to the data being transmitted. The data is
transmitted to an external device.
• When the F159 (MTRN) instruction is executed, the “transmission done” flag R9039 or R9049 goes off.
• Duplex transmission is disabled while F159 (MTRN) is being executed. The “transmission done” flag
R9039 or R9049 must be observed.

Key Point:
• The contact numbers in parentheses refer to COM2 port.

7-46
Changing communication mode of COM port
An F159 (MTRN) instruction can be executed to change between general-purpose serial communication
mode and computer link mode. To do so, specify H8000 for n (the number of transmission bytes) and
execute the instruction.

Changing from “general-purpose” to “computer link”

Changing from “computer link” to “general-purpose”

The RS232C port selection flag in R9032 or R9042 turns on when general-purpose serial communication
mode is selected.

Note:
• When the power is turned on, the operating mode selected in system register no. 412 takes effect.

7.5.4 1:N Communication (General-purpose Serial Communication)
Overview
The FPΣ and the external units are connected using an RS485 cable. Using the protocol that matches
the external units, the F159 (MTRN) instruction is used to send and receive data.

When data has been sent from FPΣ via the RS485 communication of AFPG806, start sending data to
FPΣ side after the time mentioned below passed at the receiver.
In case of 19200 bit/s: 1 ms In case of 115200 bit/s: 200µs

7.6 Communication Function 3: PC(PLC) link

7.6.1 PC(PLC) link

Overview
• The PC(PLC) link is an economic way of linking PLCs, using a twisted-pair cable.
• Data is shared between the PLCs using link relays (L) and link registers (LD).
• The statuses of the link relays and link registers of one PLC are automatically fed back to the other
PLCs on the same network.
• PC(PLC) link is not the default setting. Therefore, the setting of system register no. 412 must be
changed to “PC(PLC) link” in order to use this function.
• Unit numbers and link areas are allocated using the system registers.

7-50
Operation of PC(PLC) link
• Turning on a link relay contact in one PLC turns on the same link relay in all other PLCs on the same
network.
• Likewise, if the contents of a link register in one PLC are changed, the values of the same link register
are changed in all PLCs on the same network.

7-51
7.6.2 Setting Communication Parameters
Setting of communication mode
In the default settings, the COM port is set to computer link mode.
Set the communication mode using the FPWIN GR programming tool. Select “PLC Configuration” under
“Options”, and then select “COM1 port” tab. (The PC(PLC) link is available for COM1 port only.)

The termination resistance of the AFPG806 is specified by the dip switch located in the
communication cassette.
Note2) The baud rate of the AFPG806 must be identically set to 115200 bps by the system register and
the dip switch located in the communication cassette.

7-52
Setting of unit numbers
By default, the unit number for the communication port is set to 1 in the system registers.
In a PC(PLC) link that connects multiple PLCs on the same transmission line, the unit number must be
set in order to identify the different PLCs.

The unit number is specified either by using the unit number setting switch, SYS1 instruction or the
system register.

Note1) The priority order for station number settings is as follows:

1. Unit number settings switch
2. SYS1 instruction
3. System registers
Note2) Station numbers should be set sequentially and consecutively, starting from 1, with no breaks
between them. If there is a missing station number, the transmission time will be longer.
Note3) If fewer than 16 units are linked, the transmission time can be shortened by setting the largest
station number in system register no. 47.

Unit numbers are the numbers to identify the different PLCs on the same network. The same number
must not be used for more than one PLC on the same network.

If unit number setting switch is 0, SYS1 instruction and the system register Is valid.
If unit number setting switch is a number other than 0, the unit number setting switch is valid, and the
unit number setting with the system register is ignored. The same unit number is given to both COM1
port and COM2 port.

Note:
When using the PC(PLC) link with the RS232C, the number of units is 2.

7-53
Setting unit numbers with the setting switch
The unit number setting switch is located underneath the cover on the leftside of the FPΣ control unit.
The selector switch and the dial can be used in combination to set a unit number between 1 and 16.
(With the RS232C, a maximum of 2 unit number can be set.

Table of switch settings and related unit numbers

• The numbers in a range of 1 to 16 can
be set using the unit number setting
switch. With the RS232C, set it to 1 or 2.

• Set the unit number setting switch to 0 to

make the system register setting valid.
(Individual settings are possible using the
system register setting.)

Setting with the system register

Setting the unit number setting switch to 0 makes the system register settings valid.
Set the unit numbers using the FPWIN GR programming tool. Select “PLC Configuration” under
“Options”, and then select “COM1 port” tab.

Link area allocation
• The link relays and link registers to be used in the PC(PLC) link are allocated in the link area of the
CPU unit. Link area allocations are specified by setting the system registers of the CPU unit.

Note:
The PC(PLC) link 1 is available for the FPΣ 32k type only.
Set the system register 46 to “Reverse” to use the PC(PLC) link 1.

Link area configuration

• Link areas consist of link relays and link registers, and are divided into areas for PC(PLC) link 0 and
PC(PLC) link 1 and used with those units.
• The link relay which can ben used in an area for either PC(PLC) link 0 or PC(PLC) link 1 is maximum
1024 points (64 words), and the link register is maximum 128 words.

Note:
The PC link 1 can be used to connect with the second PC link W0 of the FP2 Multi Communication Unit
(MCU). At that time, the link relay number and link register number for the PC link can be the same
values as the FP2 (from WL64, from LD128).

 Note: Precautions for link area allocation
A mistake in the link area allocation will cause an error, and communication will be disabled.

Avoid overlapping send areas

When sending data from the send area to receive area of another FPΣ, send and receive areas must
match. In the example shown below, there is an overlapping area between units no. 2 and 3, and this will
cause an error, so that communication cannot be carried out.

Setting the largest unit number for a PC(PLC) link
The largest unit number can be set using system register no. 47 (using system register no. 57 for
PC(PLC) link 1 (for FPΣ 32k type only)).

[Sample setting]
No. of units linked Setting contents
2 1st unit: Unit no. 1 is set
2nd unit: Unit no. 2 is set
A largest unit no. of 2 is set for each.
4 1st unit: Unit no. 1 is set
2nd unit: Unit no. 2 is set
3rd unit: Unit no. 3 is set
4th unit: Unit no. 4 is set
A largest unit no. of 4 is set for each.
n Nth unit: Unit no. n is set
A largest unit no. of n is set for each.

Note:
• Unit numbers should be set sequentially and consecutively, starting from 1, with no breaks between
them. If there is a missing unit number, the transmission time will be longer.
• For all PLCs which are linked, the same value should be set for the largest unit number.
• If there are fewer than 16 units linked and the largest unit number has not been set (default=16), or the
largest unit number has been set but the unit number settings are not consecutive, or the unit number
settings are consecutive but there is a unit for which the power supply has not been turned on, the
response time for the PC(PLC) link (the link transmission cycle) will be longer.

Reference: <7.6.5 PC(PLC) Link Response Time>.

Setting PC(PLC) link switching flag (For FPΣ 32k type only)
PC(PLC) link switching flag can be set using system register no. 46.
If it is set to 0 (default value), the first half of the link relays and registers are used. If it is set to 1, the
second half of the loink relays and registers are used.

7-60
7.6.3 Monitoring
When using a PC(PLC) link, the operation status of the links can be monitored using the following relays.

Transmission assurance relays

For PC(PLC) link 0: R9060 to R906F (correspond to unit no. 1 to 16)
For PC(PLC) link 1: R9080 to R908F (correspond to unit no. 1 to 16) (For FPΣ 32k type only)
If the transmission data from a different unit is being used with the various PLCs, check to make sure the
transmission assurance relay for the target unit is on before using the data.

Operation mode relays

For PC(PLC) link 0: R9070 to R907F (correspond to unit no. 1 to 16)
For PC(PLC) link 1: R9090 to R909F (correspond to unit no. 1 to 16) (For FPΣ 32k type only)
The operation modes (RUN/PROG.) can be checked for any given PLC.

PC(PLC) link transmission error relay R9050

This relay goes on if a problem is detected during transmission.

Key Point: Monitoring the PC(PLC) link status

In FPWIN GR, the PC(PLC) link status items, such as the transmission cycle time and the number of
times that errors have occurred, can be monitored by selecting the PC(PLC) link switch on the FPWIN
GR Status Monitor screen.

Note:
Remote programming of the linked PLCs is not possible.

7.6.5 PC(PLC) link Response Time
The maximum value for the transmission time (T) of one cycle can be calculated using the following
formula.

The various items in the formula are calculated as described below.

← Ts (transmission time per station)

Ts = scan time + Tpc (PC(PLC) link sending time)
Tpc = Ttx (sending time per byte) x Pcm (PC(PLC) link sending size)
Ttx = 1/(baud rate x 1000) x 11 ms …. Approx. 0.096 ms at 115.2 kbps
Pcm = 23 + (number of relay words + number of register words) x 4

↑ Tlt (link table sending time)

Tlt = Ttx (sending time per byte) x Ltm (link table sending size)

Ttx = 1/(baud rate x 1000) x 11 ms …. Approx. 0.096 ms at 115.2 kbps

Ltm = 13 + 2 x n (n = number of stations being added)

→ Tso (master station scan time)

This should be confirmed using the programming tool.

↓ Tlk (link addition processing time) …. If no stations are being added, Tlk = 0.
Tlk = Tlc (link addition command sending time) + Twt (addition waiting time) + Tls (sending time for
command to stop transmission if link error occurs) + Tso (master station scan time)

Tlc = 10 x Ttx (sending time per byte)

Ttx = 1/(baud rate x 1000) x 11 ms …. Approx. 0.096 ms at 115.2 kbps
Twt = Initial value 400 ms (can be changed using SYS1 system register instruction)
Tls = 7 x Ttx (sending time per byte)
Ttx = 1/(baud rate x 1000) x 11 ms …. Approx. 0.096 ms at 115. 2 kbps
Tso = Master station scan time

Calculation example 1
When all stations have been added to a 16-unit link, the largest station number is 16, relays and
registers have been evenly allocated, and the scan time for each PLCs is 1 ms.
Ttx = 0.096 Each Pcm = 23 + (4 + 8) x 4 = 71 bytes Tpc = Ttx x Pcm = 0.096 x 71 ≒ 6.82 ms
Each Ts = 1 + 6.82 = 7.82 ms Tlt = 0.096 x (13 + 2 x 16) = 4.32 ms
Given the above conditions, the maximum value for the transmission time (T) of one cycle will be:
T max. = 7.82 x 16 + 4.32 + 1 = 130.44 ms

7-66
Calculation example 2
When all stations have been added to a 16-unit link, the largest station number is 16, relays and
registers have been evenly allocated, and the scan time for each PLC is 5 ms
Ttx = 0.096 Each Pcm = 23 + (4 + 8) x 4 = 71 bytes Tpc = Ttx x Pcm = 0.096 x 71 ≒ 6.82 ms
Each Ts = 5 + 6.82 = 11.82 ms Tlt = 0.096 x (13 + 2 x 16) = 4.32 ms
Given the above conditions, the maximum value for the transmission time (T) of one cycle will be:
T max. = 11.82 x 16 + 4.32 + 5 = 198.44 ms

7-67
Calculation example 3
When all but one station have been added to a 16-unit link, the largest station number is 16, relays and
registers have been allocated evenly, and the scan time for each PLC is 5 ms.
Ttx = 0.096 Each Ts = 5 + 6.82 = 11.82 ms
Tlt = 0.096 x (13 + 2 x 15) ≒ 4.13 ms
Tlk = 0.96 + 400 + 0.67 + 5 ≒407 ms
Note: The default value for the addition waiting time is 400 ms.

Given the above conditions, the maximum value for the transmission time (T) of one cycle will be:
T max. = 11.82 x 15 + 4.13 + 5 + 407 = 593.43 ms

Calculation example 4
When all stations have been added to an 8-unit link, the largest station number is 8, relays and register
have been evenly allocated, and the scan time for each PLC is 5 ms.
Ttx = 0.096 Each Pcm = 23 + (8 + 16) x 4 = 119 bytes
Tpc = Ttx x Pcm = 0.096 x 119 ≒ 11.43 ms
Each Ts = 5 + 11.43 = 16.43 ms Tlt = 0.096 x (13 + 2 x 8) ≒ 2.79 ms

Given the above conditions, the maximum value for the transmission time (T) of one cycle will be:
T max. = 16.43 x 8 + 2.79 + 5 = 139.23 ms

Calculation example 5
When all stations have been added to a 2-unit link, the largest station number is 2, relays and registers
have been evenly allocated, and the scan time for each PLC is 5 ms.
Ttx = 0.096 Each Pcm = 23 + (32 + 64) x 4 = 407 bytes
Tpc = Ttx x Pcm = 0.096 x 407 ≒ 39.072 ms
Each Ts = 5 + 39.072 = 44.072 ms Tlt = 0.096 x (13 + 2 x 2) ≒ 1.632 ms

Given the above conditions, the maximum value for the transmission time (T) of one cycle will be:
T max. = 44.072 x 2 + 1.632 + 5 = 94.776 ms

Calculation example 6
When all stations have been added to a 2-unit link, the largest station number is 2, 32 relays and 2
register words have been evenly allocated, and the scan time for each PLC is 1 ms.
Ttx = 0.096 Each Pcm = 23 + (1 + 1) x 4 = 31 bytes
Tpc = Ttx x Pcm = 0.096 x 31 ≒ 2.976 ms
Each Ts = 1 + 2.976 = 3.976 ms Tlt = 0.096 x (13 + 2 x 2) ≒ 1.632 ms

Given the above conditions, the maximum value for the transmission time (T) of one cycle will be:
T max. = 3.976 x 2 + 1.632 + 1 = 10.584 ms

Note:
• In the description, “stations that have been added” refers to stations which are connected between
station no. 1 and the largest station number and for which the power supply has been turned on.
• Comparing examples 2 and 3, the transmission cycle time is longer if there is one station that has not
been added to the link. As a result the PC(PLC) link response time is longer.
• The SYS1 instruction can be used to minimize thte transmission cycle time even if there are one or
more stations that have not been added to the link.

7-68
Reducing the transmission cycle time when there are stations that have not been added
If there are stations that have not been added to the link, the Tlk time (link addition processing time) and
with this the transmission cycle time will be longer.

With the SYS1 instruction, the link addition waiting time Twt in the above formula can be reduced. Thus,
SYS1 can be used to minimize the increase in the transmission cycle time.

<Programming example of SYS1 instruction>

(SYS1, M PCLK1T0, 100) Noe)

Function:
Setting SYS1 to change the waiting time for a link to be added to the PC(PLC) link from the default value
of 400 ms to 100 ms.
Keywords:
Setting for key word no. 1: PCLK1T0
Permissible range for key word no. 2: 10 to 400 (10 ms to 400 ms)
Note) Enter one space after M and then enter 12 characters to be aligned to the right.
If the second keyword is 2 digits, put 2 spaces, and if it is 3 digits, put one space.

Note:
If there are any stations that have not been added to the link, the setting should not be changed
as long as a longer link transmission cycle time does not cause any problem.
• The SYS1 instruction should be executed at the beginning of the program, at the rise of R9014. The
same waiting time should be set for all linked PLCs.
• The waiting time should be set to a value of at least twice the maximum scan time for any of the PLCs
connected to the link.
• If a short waiting time has been set, there may be PLCs that cannot be added to the link even if their
power supply is on. (The shortest time that can be set is 10 ms.)

7-69
Error detection time for transmission assurance relays
The power supply of any given PLC fails or is turned off, it takes (as a default value) 6.4 seconds for the
transmission assurance relay of the PLC to be turned off at the other stations. This time period can be
shortened using the SYS1 instruction.

<Programming example of SYS1 instruction>

(SYS1, M PCLK1T1, 100) Note)

Function:
Setting SYS1 to change the time that the PC(PLC) link transmission assurance is off from the default
value of 6400 ms to 100 ms.
Keywords:
Setting for key word no. 1: PCLK1T1
Permissible range for key word no. 2: 100 to 6400 (100 ms to 6400 ms)
Note) Enter one space after M and then enter 12 characters to be aligned to the right.
If the second keyword is 3 digits, put 2 spaces, and if it is 4 digits, no space is needed.

Note:
The setting should not be changed as long as a longer transmission assurance relay detection
time does not cause any problems.
• The SYS1 instruction should be executed at the beginning of the program, at the rise of R9014. The
same time should be set for all linked PLCs.
• The time should be set to a value of at least twice the maximum transmission cycle time when all of the
PLCs are connected to the link.
• If short time has been set, the transmission assurance relay may not function properly. (The shortest
time that can be set is 100 ms.)

7.7 Communication Function 4: MODBUS RTU
Communication

7.7.1 MODBUS RTU Communication

Function overview
• This function is available for the 32k type only.
• The MODBUS RTU protocol enables the communication between the FPΣ and other devices (including
our FP-e, Programmable display GT series and KT temperature control unit).
• Enables to have conversations if the master unit sends instructions (command messages) to slave
units and the slave units respond (response messages) according to the instructions.
• Enabels the communication between the devices of max. 99 units as the master function and slave
function is equipped.

About MODBUS RTU

• The MODBUS RTU communication is a function for the master unit to read and write the data in slave
units communicating between them.
• There are ASCII mode and RTU (binary) mode in the MODBUS protocol, however, the FPΣ is
supported with the RTU (binary) mode only.

Master function
Writing and reading data for various slaves is available using the F145 (SEND) and F146 (RECV)
instructions.
Individual access to each slave and the global transmission is possible.

Slave function
If the slave units receive a command message from the master unit, they send back the response
message corresponding to the content.
Do not execute the F145 (SEND) or F146 (RECV) instructions when the unti is used as a slave unit.

Security Functions
8.1 Type of Security Functions
There are mainly two functions as the security function of the FPΣ.
It is possible to rewrite data during any of these functions is being used.

1: Password protect function

It is used to restrict the access to the programs in the FPΣ from the programming tool by setting
a password. Writing and reading ladder programs or system registers will be unperformable by
setting a password and setting to the protect mode.
There are two types of passwords as below.

• 4-digit password: 4 characters of 16 characters that are “0” to “9” and “A” to “F” can be used.
• 8-digit password: A maximum of 8 English one byte characters (case-sensitive) and symbols
can be used.
Note) 8-digit password is available for FPΣ 32k type only.

2: Upload protection (Available for FPΣ 32k type only)

Ladder programs or system registers cannot be uploaded from the FPΣ by setting that the
program is not uploaded. As transferring programs to the master memory cassette as well as the
programming tool will be unperformable, it ensures higher security.

3: Password protect function and upload protection for FP memory loader

Those functions are available only when using the 32k-type FPΣ V3.2 or later, FP memory loader
V2.0 or later and FPWIN GR V2.8 or later and when setting a 8-digit password.

Reference: <8.4 Setting Function for FP Memory Loader>

The state of the security can be checked at two displays of the programming tool FPWIN GR.
1. Select [Online Edit Mode] under the [Online] on the menu bar, or press the [CTRL] and [F2] keys at
the same time, to switch to the [Online] screen.

9.2 Sampling Trace Function 32k Type Only

9.2.1 Overview
The FPΣ control unit Ver3.10 and later versions support the sampling trace function.
Using this function enables to take samplings and record (accumulate) the state of artibrary data of 16
bits + 3 data registered in the PLC at an arbitrary timing, and to examine the changes in the bit and data
in details after stopping sampling at an arbitrary timing.

The sampling trace function is used in the time chart monitor function under the online menu of the
FPWIN GR.

The instructions, functions, special relays and special registers related to the sampling trace
function are as below.
F155(SMPL) sampling instruction
F156(STRG) sampling stop trigger instruction
Time charge monitor of FPWIN GR

R902C : Sample point flag OFF=Sampling by instruction

ON=Sampling at regular time intervals

9.2.2 Details of Sampling Trace Function

No. of data collectable at one sampling: 16 bits +3 data
Sampling capacity (No. of samples accumulable) : 1000 samples
Types of sampling timing (When an instruction is exected, or at regular time intervals)
1: Sampling at regular time intervals From 10 ms
2: Sampling by F155(SMPL) instruction

Sampling for every scan can be executed by the instruction.

Also, more than one samplings can be executed in one scan.
Timing for the execution of the F155(SMPL) instruction can be set by the ladder sequence.

Note: It is not possible to activate the sampling at regular time intervals and the sampling by the
F155(SMPL) instruction simultaneously.

How to stop sampling

Methods of the stop trigger (request): Following two methods are available.

1. Deactivate request by the tool software

2. Deactivate request by the F156(STRG) instruction

If the stop trigger activates, the PLC will continue to take samplings for the specified No. of delay, and
then stop the sampling operaton. Once the sampling operation stops, the data will be automatically
retrieved by the tool software and will be indicated in a time chart.
It is possible to adjust whether to see before or after the trigger point by the setting of the No. of delay.

10.2 Troubleshooting

10.2.1 If ERROR/ALARM LED is Flashing

Condition: The self-diagnostic error occurs
Procedure 1
Check the error contents (error code) using the programming tool.

Using FPWIN GR
With the FPWIN GR Ver. 2, if a PLC error occurs during programming or debugging and the RUN mode
is changed to the PROG. mode, the following status display dialog box is displayed automatically.
Check the contents of the self-diagnosed error.

Status display dialog box

If the error is an operation error, the error
address can be confirmed in this dialog
box.

After correcting the error, click on the

“Clear Error” button to clear the error.

Key Point:
To display the status display dialog box, select “Status Display” under “Online” on the menu bar.

Procedure 2
<For error code is 1 to 9>
• Condition
There is a syntax error in the program.
• Operation 1
Change to PROG. mode and clear the error.
• Operation 2
Execute a total-check function using FPWIN GR to determine the location of the syntax error.

10-3
<For error code is 20 or higher>
• Condition
A self-diagnostic error other than a syntax error has occurred.
• Operation 1
Use the programming tool in PROG. mode to clear the error.
Using FPWIN GR
Click on the “Clear Error” button in the “Status display dialog box”. Error code 43 and higher can be
cleared.
• In the PROG. mode, the power supply can be turned off and then on again to clear the error, but all of
the contents of the operation memory except hold type data arecleared.
• An error can also be cleared by executing a self-diagnostic error set instruction F148 (ERR).

Key Point:
When an operation error (error code 45) occurs, the address at which the error occurred is stored in
special data registers DT90017 and DT90018. If this happens, click on the “Operation Err” button in the
“Status display dialog box” and confirm the address at which the error occurred before cancelling the
error.

10.2.2 If ERROR/ALARM LED is ON

Precautions During Programming
11.1 Use of Duplicated Output

11.1.1 Duplicated Output

What is duplicated output?
• Duplicated output refers to repeatedly specifying the same output in a sequence program.
• If the same output is specified for the “OT” and “KP” instructions, it is considered to be duplicated
output.
(Even if the same output is used for multiple instructions, such as the SET, RST instruction or high-
level instruction (such as data transfer), it is not regarded as duplicated output.)
• If you enter RUN mode while the duplicated output condition exists, it will be normally flagged as an
error. (The ERROR/ALARM LED will flash and the self-diagnostic error flag R9000 will go on.)

How to check for duplicated use

You can check for duplicated outputs in the program using the programming tool, by the following
method.
- Using the tool software
Select the “Debug” → “Totally Check Program” in the menu bar, and click “Execute”. If there are any
duplicated outputs, an error message and the address will be displayed.

Enabling duplicated output

• If you need to use output repeatedly due to the content of the program, duplicated output can be
enalbed.
• In this case, change the setting of system register 20 to “enable”.
• When this is done, an error will not occur when the program is executed.

11.1.2 When Output is Repeated with an OT, KP, SET or RST Instruction
Condition of internal and output relays during operation
• When instructions are repeatedly used which output to internal and output relays such as transfer
instructions and OT, KP, SET and RST instructions, the contents are rewritten at each step during
operation.
<Exmaple>
Processing when SET, RST and OT instructions are used (X0 to X2 are all on).

11-2
The output is determined by the final operation results
• If the same output is used by several instructions such as the OT, KP, SET, RST or data transfer
functions, the output obtained at the I/O update is determined by the final results of the operation.
<Exmaple>
Output to the same output relay Y0 with OT, KP, SET and RST instructions.

When X0 to X2 are all on, Y0 is output as off at I/O update.

• If you need to output a result while processing is still in progress, use a partial I/O update instruction
(F143).

11-3
11.2 Handling BCD Data

11.2.1 BCD Data

BCD is an acronym for binary-coded decimal, and means that each digit of a decimal number is
expressed as a binary number.
<Example> Expressing a decimal number in BCD:

11.2.2 Handling BCD Data in the PLC

• When inputting data from a digital switch to the PLC or outputting data to a 7-segment display (with a
decoder), the data must be in BCD form. In this case, use a data conversion instruction as shown in the
examples at below.
• BCD arithmetic instructions (F40 to F58) also exist which allow direct operation on BCD data, however,
it is normally most convenient to use BIN operation instructions (F20 to F38) as operation in the PLC
takes place in binary.

Input from a digital switch

Use the BCD-to-BIN conversion instruction F81.

Output to a 7-segment display (with decoder)

Use the BIN-to-BCD conversion instruction F80.

11-4
11.3 Handling Index Registers

11.3.1 Index Registers

• Like other registers, index registers have 14 points, I0 to ID, for reading and writing 16-bit data.
• Use an index register to indirectly specify a memory area number. (This is also called index
modification.)

<Example>
Transferring the contents of data register DT100 to the number specified by the contents of an
index register.

In this example, the number of the destination data register varies depending on the contents of I0 with
DT0 acting as a base. For example, when I0 contains K10, the destination will be DT10, and when I0 is
K20, the destination will be DT20.

• In this way, index registers allow the specification of multiple memory areas with a single instruction,
and thus index registers are very convenient when handling large amounts of data.

11.3.2 Memory Areas Which can be Modified with Index Registers

• Index registers can be used to modify other types of memory areas in addition to data registers DT.
<Example> I0WX0, I0WY1, I0WR0, I0SV0, I0EV2, I0DT100
• Constants can also be modified.
<Example> I0K10, I0H1001
• An index register cannot modify another index register.
<Example> I0I0, I0I1
• When using index modification with an instruction which handles 32-bit data, specify with I0. In this
case, I0 and I1 are handled together as 32-bit data.

11-5
11.3.3 Example of Using an Index Register
Repeatedly reading in external data
<Example>
Writing the contents of input WX3 to a sequence of data registers beginning from DT0.

When R0 turns on, 0 is written to index register I0.

When the R1 turns on, the contents of input WX3 is transferred to the data register specified by
I0DT0.
Add 1 to I0. In this case, the contents of I0 will change successively, and the destination data register
will be as follows.
Input times of R1 Contents of I0 Destination data register
1st 0 DT0
2nd 1 DT1
3rd 2 DT2
: : :

Inputting and outputting data based on a number specified by an input

<Example 1> Setting a timer number specified by a digital switch

Convert the BCD timer number data in WX1 to binary and set it in index register I0.
Convert the BCD timer set value in WX0 to binary and store in the timer set value area SV specified
by contents of I0.

<Example 2>
Taking external output of the elapsed value in a timer number specified by a digital switch

Convert the BCD timer number data in WX1 to binary and set it in index register I0.
Convert the elapsed value data EV in the timer specified by I0 to BCD, and output it to output relay
WY0.
11-6
11.4 Operation Errors

11.4.1 Outline of Operation Errors

• An operation error is a condition in which operation is impossible when a high-level instruction is
executed.
• When an operation error occurs, the ERROR/ALARM LED on the control unit will blink and the
operation error flags (R9007 and R9008) will turn on.
• The operation error code “E45” is set at special data register DT90000.
• The error address is stored in special data registers DT90017 and DT90018.

Types of operation error

1. Address error
The memory address (number) specified by index modification is outside the aera which can be used.
2. BCD data error
Operation is attempted on non-BCD data when an instruction handling BCD is executed, or BCD
conversion is attempted on data which is not within the possible conversion range.
3. Parameter error
In an instruction requiring the specification of control data, the specified data is outside the possible
range.
4. Over area error
The data manipulated by a block instruction exceeds the memory range.

11.4.2 Operation Mode When an Operation Error Occurs

• Normally, the operation stops when an operation error occurs.
• When you set system register 26 to “continuation”, the control unit operates even if an operation error
occurs.

Using programming tool software

1. Set the mode of the CPU to PROG.
2. Select the “Option” in “PLC Configuration” option from the menu bar.
3. On the “PLC Configuration” menu, select “Action on error”. This displays system registers 20 to 26.
4. Remove the check of system register 26.
5. Press the “OK” to write the setting to the PLC.

11.4.3 Dealing with Operation Errors

<Procedure>
1. Check the location of the error.
Check the address where the error occurred, which is stored in DT90017 and DT90018, and make sure
the high-level instruction for that address is correct and appropriate.
2. Clear the error.
Use a programming tool to clear the error.
• Select “Online” → “Status Display” in the menu bar. Execute “Clear Error”.

• An error can be cleared by turning the power off and on in PROG. mode, however, the contents of the
operation memory except the hold type data will be cleared.
• An error can also be cleared by executing a self-diagnostic error set instruction (F148).
• If the mode selector is set to “RUN”, RUN will resume as soon as the error is cleared. So if the cause of
the error is not removed, the error may seem not to be cleared.
11-7
11.4.4 Points to Check in Program
1. Check if an extraordinarily large value or negative value was stored in the index register.
<Example> When a data register is modified using an index register

In this case, index register modifies the address of data register DT0. If data in I0 is too large, it will
exceed the addressable range of the data register. The last address of the data register is DT32764, so
if the contents of I0 exceeds 32764, an operation error will occur. The same is true when the contents of
I0 are a negative value.

2. Is there any data which cannot be converted using BCD ↔ BIN data conversion?
<Example> When BCD-to-BIN conversion is attempted

In this case, if DT0 contains a hexadecimal number with one of the digits A through F such as 12A4,
conversion will be impossible and an operation error will result.

<Example> When BIN-to-BCD conversion is attempted

In this case, if DT1 contains a negative value or a value greater than K9999, an operation error will occur.

3. Check if the divisor of a division instruction is “0”.

<Example>

In this case, if the content of DT100 is “0”, an operation error will occur.

11.5 Instruction of Leading Edge Detection Method

11.5.1 Instructions of Leading Edge Detection Method

Instructions using the leading edge detection operation
1. DF (leading edge differential) instructions
2. Count input for CT (counter) instructions
3. Count input for F118 (UDC up-down counter) instructions
4. Shift input for SR (shift register) instructions
5. Shift input for F119 (LRSR left-right shift register) instructions
6. NSTP (next step) instructions
7. Differential execution type high-level instruction (P13)

Leading edge detection method

• An instruction with a leading edge detection method operates only in the scan where its trigger
(execution condition) is detected switching from off to on.

(1) Standard operation

(2) Leading edge detection operation

How to perform leading edge detection

The condition of the previous execution and the condition of the current execution are compared, and the
instruction is executed only if the previous condition was off and the current condition is on. In any other
case, the instruction is not executed.

Precautions when using an instruction which performs leading edge detection

• When RUN begins, for example when the system is powered on, the off → on change of the execution
condition (trigger) is not detected. The instruction is not executed. Execution of the instruction will take
place as explained on the next page.
• When used with one of the instructions indicated in instructions 1 to 6 below which change the order of
execution of instructions, the operation of the instruction may change depending on input timing. Take
care regarding this point.

Be careful when using leading edge detection type instructions with control instructions, such
as:
1. MC and MCE instructions
2. JP and LBL instructions
3. LOOP and LBL instructions
4. CNDE instruction
5. Step ladder instructions
6. Subroutine instructions

11-9
11.5.2 Operation and Precautions When RUN Starts
Operation of first scan after RUN begins
• The leading edge detection instruction is not executed when the mode has been switched to the RUN
mode, or when the power supply is booted in the RUN mode, if the trigger (execution condition) is
already on.

• If you need to execute an instruction when the trigger (execution condition) is on prior to switching to
RUN mode, make a program as below using R9014 (initial pulse off relay). (R9014 is a special internal
relay which is off during the first scan and turns on at the second scan.)

<Example 1> DF (leading edge differential) instruction

<Example 2> CT (counter) instruction

11-10
11.5.3 Precautions When Using a Control Instruction
• If a leading edge detection instruction is in a control instruction, it will be executed only under the
following condition: The leading edge detection instruction was off when the execution condition of the
previous control instruction was reset, and the leading edge detection instruction is on when the
execution condition of the current control instruction becomes on.
• When a leading edge detection instruction is used with an instruction which changes the order of
instruction execution such as MC, MCE, JP or LBL, the operation of the instruction may change as
follows depending on input timing. Take care regarding this point.

<Example 1> Using the DF instruction between MC and MCE instructions

11-11
<Example 2> Using the CT instruction between JP and LBL instructions

11-12
11.6 Precautions for Programming
Programs which are not executed correctly
Do not write the following programs as they will not be executed correctly.
<Example 1>

• When X1 was on prior to X0, Y0 will not be on even if X0 becomes on.

<Example 2>

• TMX will activate if X1 becomes on whether X0 is on or off.

<Example 3>

• When X2 was on prior to X0, Y1 will not be on even if X0 becomes on.

When a combination of contacts are set as the trigger (execution condition) of a differential instruction
(DF) or timer instruction, do not use an AND stack (ANS) instruction, read stack (RDS) instruction, or
pop stack (POPS) instruction.

Examples in which the above programs are rewritten

<Program in which the example 3 is rewritten>

11-13
11.7 Rewrite Function During RUN

11.7.1 Operation of Rewrite During RUN

How operation of rewrite during RUN
Rewriting programs can be executed even in RUN mode. When a rewrite is attempted during RUN, the
tool service time is temporarily extended, program rewriting is performed, and operation is resumed
without the need to change the mode. For this reason, the time of the scan during the RUN rewrite
extends from several ms to several hundreds of ms.

Operation during rewrite

External output (Y) is held.
External input (X) is ignored.
The timer (T) stops the clock.
Rise and fall changes in the inputs of differential instructions (DF), counter instructions (CT), and
left/right shift registers are ignored.
Interrupt functions are stopped.
Internal clock relays (special internal relays) are also stopped.
Pulse output is stopped during the rewrite.

Set values for timer/counter instructions

All set values specified with decimal constants (K) in timer and counter instructions are preset in the
corresponding set value areas (SV). Values in the elapsed value area (EV) do not change.

Operation of rewrite during RUN completed flag

The rewrite during RUN completed flag (R9034) is a special internal relay that goes on for only the first
scan following the completion of rewriting in the RUN mode. It can be used instead of the initial pulse
relay following a change in the program.

11-14
11.7.2 Cases Where Rewriting During Run is not Possible
When the timeout error message is indicated:
Even if the timeout error message is indicated, it is highly possible that the program in PLC has been
already rewritten. Carry out the following operations.

1. When ladder symbol mode

As a ladder editing is left, set it to the offline edit mode. Complete the program conversion in the tool
software, and then change to the online edit mode to check.
2. When boolean mode
A ladder editing is cleared.
Set it to the offline edit mode and carry out the editing operation again. After the operation, change to the
online edit mode to check.

When the timeout error occurs using the through mode in GT series programmable display.
Extend the timeout time of the programmable display using the GTWIN.
(The default setting is 5 seconds.)

Select “Transfer” from “File” in the menu bar. The

“transfer data” screen will open. Select “Condition” to
open “Communication Setting” screen.
Change the value for “Timeout”.
Click “OK” button to complete the change of setting.

11-15
Cases where rewriting is not possible during RUN
1. When the result of rewriting is a syntax error.
<Example>
When executing the rewriting which does not form the following pair of instructions.
1. Step ladder instructions (SSTP/STPE)
2. Suroutine instructions (SUB/RET)
3. Interrupt instructions (INT/IRET)
4. JP/LBL
5. LOOP/LBL
6. MC/MCE

Also, rewritng is not possible during RUN in case of other syntax errors.

2. During the forced input/output operation

Interrupt restrictions
When using interrupt, high-speed counter, pulse output or PWM output functions, do not perform a
rewrite during RUN.
If a rewrite during RUN is executed, the operation as below will be performed. Exercise caution.

1. Interrupt programs will be disabled. Enable by executing an ICTL instruction once again.
<Example> Using R9034 (rewrite during RUN completed flag)

2. The high-speed counter will continue to count.

Target value match on/off instructions (F166/F167) will continue.
Coincidence interrupt programs will be disabled when the F166/F167 instruction is running.

3. The pulse output/PWM output stops when the rewriting is performed.

The operation after the completion of the rewriting during RUN varies depending on each instruction.
Instruction Name Operation after the completion of
number rewriting during RUN
F171 (SPDH) Pulse output (Trapezoidal control) The operation before rewriting continues.
F171 (SPDH) Pulse output (Home position return) The operation before rewriting continues.

11.8 Processing During Forced Input and Output

11.8.1 Processing when forced input/output is initiated during RUN

1. Processing of external input (X)

• Regardless of the state of the input from the input device, forced on/off operation will take precedence
at a contact specified for forced input/output in the above procedure B. At this time, the input LED will
not blink, however, the area of input X in the operation memory will be rewritten.
• Contacts not specified will read in the on/off state according to the condition of the inptu from the input
device.

2. Processing of external output (Y)

• Regardless of the result of operation, forced on/off will take precedence at a contact specified for
forced input/ouput in the above procedure A. At this time, the area of output Y in the operation memory
will be forcedly rewritten. External output will take place according to the input/output update timing in
the above diagram.
• The on/off state of contacts not specified will be determined by the operation result.

3. Processing of Timer (T) and Counter (C)

• Regardless of the timer/counter input condition, forced on/off operation will take precedence at a
contact specified for forced input/output. At this time, the contact of the timer (T) or counter (C) in the
operation memory will be rewritten. Timing and counting will not take place during control.
• The on/off state of contacts not specified will be determined by the operation result.

Operation during operation

For small-sized PLCs FP0, FP1, FPΣ and FP-X
The internal relay R or output Y specified by OT or KP instruction is rewritten according to the results of
operation. However, as the R or Y is set/reset again right before the peripheral service (as the above
procedure C), the monitoring value with the tooling software or the output to external devices is forcibly
rewritten to a specified value.

For medium-sized PLCs FP2 and FP2SH

For the internal relay R and output Y specified by OT or KP instruction, the value of the forced
processing has a priority. When rewritten by a high-level instruction, the result of the instruction has a
priority.

Note1) When connecting a commercially available device that has an RS485 interface, please confirm
operation using the actual device. In some cases, the number of units, transmission distance,
and baud rate vary depending on the connected device.

12-10
Note2) The values for the transmission distance, baud rate and number of units should be
within the values noted in the graph below.

When using a baud rate of 2400 bps to 38400 bps, you can set up to a maximum of
99 units (stations) and maximum transmission distance of 1200 m.

Note3) Only 9600 bps or 19200 bps can be specified when the C-NET adapter is connected with the
RS485 interface.
Note4) The start code and end code can be used only in the general-purpose serial communication
mode.
Note5) The converter SI-35 manufactured by Lineeye Co., Ltd is recommendable for the RS485 at the
computer side. Adjust the response time for the FP-X by the SYS1 instruction if necessary.
Note6)Regarding the setting of unit numbers:
When the unit number setting switch is “0”, the system register is effective.
When the unit number setting switch is other than “0”, the unit number setting switch is effective,
and the unit number setting of the system register is ignored.
(Max. 31 units can be specified with the unit number setting switch.) (When the setting is specified
with the unit number setting switch, the COM port 1 and the COM port 2 has the same unit
number.
Note7)Connect the “−“ terminal and the “+” terminal with a lead wire to make the termination resistance
of the AFPG803 effective.
The termination resistance of the AFPG806 is specified by the dip switch in the communication
cassette.
There is no termination resistance at the RS232C port.
Note8) The RS485 port of the AFPG806 is either 19200 bps or 115200 bps only.
Also the baud rate must be identically set by the system register and the dip switch in the
communication cassette. The baud rate for the PC(PLC) link mode is fixed at 115200 bps.
The baud rate for the RS232C port of the AFPG806 can be set by the system register only.
Note9) The MEWTOCOL master function, MODBUS RTU master function and general-purpose serial
communication function at the TOOL port is available only for the FPΣ 32k type.

14.1 System Registers / Special Internal Relays / Special
Data Registers
Precation for System Registers

What is the system register area

• System registers are used to set values (parameters) which determine operation ranges and functions
used. Set values based on the use and specifications of your program.
• There is no need to set system registers for functions which will not be used.

Type of system registers

The registers to be used depend on each PLC.

(1) Allocation of timers and counters (System register 5)

The number of timers and counters is set by specifying the starting counter number.
(2) Hold/non-hold type setting (System registers 6 to 13)
When these registers are set to “hold type”, the values in the relays and data memory will be retained
even if the system is switched to PROG. mode or the power is turned off. If set to “non-hold type”, the
values will be cleared to “0”.
(3) Operation mode setting on error (System registers 4, 20 to 26)
Set the operation mode when errors such as battery error, duplicated use of output, I/O verification error
and operation error occur.
(4) Time settings (System registers 31 to 34)
Set time-out error detection time and the constant scan time.
(5) MEWNET-W0 PLC link settings (System registers 40 to 47, 50 to 57)
These settings are for using link relays and link registers for MEWNET-W0 PC(PLC) link communication.
Note) The default value setting is “no PC(PLC) link communication”.
(6) Input settings (System registers 400 to 403)
When using the high-speed counter function, pulse catch function or interrupt function, set the operation
mode and the input number to be used for the function.
(7) Tool and COM. ports communication settings (System registers 410 to 421)
Set these registers when the Tool port,and COM1 and COM2 ports are to be used for computer link,
general-purpose serial communication, PC(PLC) link, and modem communication.Note that
the default setting is computer link mode.

14-2
Checking and changing the set value of system register
If you are going to use a value which is already set(the value which appears when read),
there is no need write it again.

Using programming tool software

Produce:
1. Set the control unit in the PROG mode.
2.Option ->PLC Configuration
3.When the function for which setting are to be entered is selected in the PLC Configuration
dialog box,the value and setting status for the selected system register are displayed.
To change the value and setting status,write in the new value and /or select the setting status.
4.To register these settings,choose OK

Precautions for system register setting

-System register settings are effective from the time they are set.
However, input settings,tool port,COM port,and modem connection settings become effective when the
mode is changed from PROG. to RUN. With regard to the modem connection setting, when the power
is turned off and on or when the mode is changed from PROG. to RUN, the controller sends a
command to the modem which enables it for reception.
-When the initialized operation is performed, all set system register values (parameters) will be initialized

invalid in part2 of system register 401.
Note2) If reset input settings overlap, the CH1 setting takes precedence in system register 400 and the
CH3 setting takes precedence in system register 401.
Note3) The settings for pulse catch and interrupt input can only be specified in system registers 402 and

Note4) If system register 400 to 403 have been set simultaneously for the same input relay,the follwing
precedence order is effective: [High-speed counter]→[Pulse catch]→[Interrupt input].
<Example>
When the high-speed counter is being used in the addition input mode, even if input X0 is
specified as an interrupt input or as pulse catch input, those settings are invalid, and X0

14.3 Table of High-level Instructions
The high-level instructions are expressed by the prefixes “F” or “P” with numbers. For most of the high-level
instructions, “F” and “P” types are available. The differences between the two types are explained as follows:
- Instructions with the prefix “F” are executed in every scan while its trigger is in the on.
- Instructions with the prefix “P” are executed only when the leading edge of its trigger is detected.
For the FP0/FP0R/FPΣ/FP-X, the P type high-level instructions are not available.

Error Confirmation When ERROR Turns ON

When the “ERROR” on the control unit (CPU unit) turns on or flashes, a self-diagnostic error or syntax
check error has occurred. Confirm the contents of the error and take the appopriate steps.

-Error Confirmation Method

Procedure:1.Use the programming tool software to call up the error code.
By executing the “STATUS DISPLAY”, the error code and content of error are
displayed.
2.Check the error contents in the table of error codes using the error code
ascertained above.

-Syntax check error

This is an error detected by the total check function when there is a syntax error or incorrect setting
written in the program. When the mode selector is switched to the RUN mode, the total check function
automatically activates and eliminates the possibility of incorrect operation from syntax errors in the
program.

When a syntax check error is detected

-ERROR turns on or flashes.
-Operation will not begin even after swirching to the RUN mode.
-Remote operation cannot be used to change to RUN mode.

Clearing a syntax check error

By changing to the PROG.mode, the error will clear and the ERROR will turn off.

Steps to take for syntax error

Change to the PROG. mode, and then execute the total check function while online mode with the
programming tool connected. This will call up the content of error and the address where the error
occurred.
Correct the program while referring to the content of error.

14-61
-Self-diagnostic Error
This error occurs when the control unit (CPU unit) self-diagnostic function detects the occurrence of an
abnormality in the system. The self-diagnostic function monitors the memory abnormal detection, I/O
abnomal detection, and other devices.

When a self-diagnostic error occurs

- The ERROR turns on or flashes.
- The operation of the control unit (CPU unit) might stop depending on the contect of error and the
system
register setting.
- The error codes will be stored in the special data register DT9000(DT90000).
- In the case of operation error, the error address will stored in the DT9017(DT90017) and
DT9018(DT90018).

Clearing the self-diagnostic error

At the “STATUS DISPLAY”, execute the “error clear”. Error codes 43 and higher can be cleared.
-You can use the initialize/test switch to clear an error. However, this will also clear the contents of
operation memory.
-Errors can also be cleared by turning off and on the power while in the PROG.mode.
However, the contents of operation memory, not stored with the hold type data, will also be cleared.
-The error can also be cleared depending on the self-diagnostic error set instruction F148(ERR).

Steps to take for self-diagnostic error

The steps to be taken will differ depending on the error contents. For more details, use the error code
obtained above and consult the table of aself-diagnostic error codes.

MEWTOCOL-COM Transmission Errors

These are error codes from a PC or other computer device that occur during an abnormal response
when communicating with a PLC using MEWTOCOL-COM.
