Before You Start
Operating environment (Use the unit within the range of the general specifications when installing)
*Ambient temperatures:0 ~ +55 ℃
*Ambient humidity: 10% to 95% RH (at 25°C, non-condensing)
*Keep the height below 2000m.
*For use in pollution Degree 2 environment.
*Do not use it in the following environments.
- Direct sunlight
- Sudden temperature changes causing condensation.
- Inflammable or corrosive gas.
- Excessive airborne dust, metal particles or saline matter.
- Benzine, paint thinner, alcohol or other organic solvents or strong alkaline solutions such as ammonia
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.
(Min.100mm or less）

Static electricity
-Before touching the unit, always touch a grounded piece of metal in order to discharge static electricity.
-In dry locations, excessive static electricity can cause problems.

Wiring the Power Supply to the Control Unit

-Use a power supply wire that is thicker than 2 mm2 (AWG14), and twist it.
-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 an 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 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.

Operation procedure when using FPWIN GR Ver.2

Select “Online Edit Mode” on the FPWIN GR “On line” menu.
Select “Clear Program” on the “Edit” menu.
When the confirmation dialog box is displayed, click on “Yes” to clear the program.

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
password is forcibly bypassed, the program is deleted. When specifying the password, note it in the
specification manual or in another safe location in case it is forgotten at some point.
- Upload protection
When the upload protection setting is specified, programs will be disabled to be read out. If the setting
is cancelled forcibly, all programs and system registers will be deleted. Therefore, note that programs
and system registers should be managed on your own responsibility.

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

5-4
5.2 Expansion Method

5.2.1 How to Connect With FP-X Expansion Unit

The expansion unit is connected to the control unit with an exclusive expansion cable.
- The expansion cable (AFPX-EC08) is packaged with the expansion unit and expansion FP0 adapter.
The expansion cables (AFPX-EC30, AFPX-EC80) are sold separately.

How to connect
The procedure is as follows.
1 Remove the expansion cover.
○
2 Fit the expansion cable into the connectors of the control unit and expansion unit.
○
3 Fold the expansion cable to touch the units each other.
○
4 As for the expansion unit at the last position, turn on the terminator setting switch.
○
5 Install the expansion cover.
○

Note:
- The total length of the expansion cables should be within 160 cm.
- Keep the expansion cables away from the devices and wirings generating noises as much as possible.

5-5
5.3 Power Supply

5.3.1 AC Power Supply

Wiring of power supply

Allowable voltage Allowable frequency

Rated input voltage Rated frequency
amplitude range range
100 to 240 V AC 85 to 264 V AC 50/60 Hz 47 to 63 Hz

Note:
Using the power supply of the outlying voltage and frequency, or using inappropriate wires may cause
the fault of the power supply of the PLC.

Isolation of power supply systems

Isolate the wiring systems to the PLC, output devices and mechanical power apparatus.

Note: Power supply of the expansion units

Be sure to supply power to the expansion units and the control unit from the same power supply, and
turn the power on and off simultaneously for both.

5-6
To avoid the influence of noises
Use the power supply causing less noise. The inherent noise resistance is sufficient for the noise
superimposed on the power wires; however, the noise can be attenuated further by using the isolation
transformer.
Also, twist the power supply cables to minimize adverse effects from noise.

Grounding
Ground the instrument to increase noise suppression.

Exclusive grounding
• For grounding purposes, use wiring with a minimum of 2 mm2. 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.

5.3.2 Service Power Supply for Input (For L30, L40 and L60 types)
Service power supply for input
- Use it for input and the expansion FP0 adapter. (Use an external power supply for the FP0/FP0R
expansion unit.)
- When it is used for another device, confirm the consumption current of the device side before it is
connected. If excess current is being supplied for a long time, the power supply may be damaged.

5-7
5.4 Wiring of Input and Output

5.4.1 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 lead switch

When a LED is connected in series to an input

contact such as LED-equipped lead 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 several 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.

5-8
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.

5.4.2 Output Wiring

Do not connect a load that exceeds the maximum switching ability to the output terminal.

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 diode across the ends
of the load.
When using an AC inductive load

When using a DC inductive load

5-9
Precautions when using capacitive loads
When connecting loads with large in-rush currents, to minimize their effect, connect a protection circuit
as shown below.

5.4.3 Precautions Regarding Input and Output Wirings

Isolate input/output/power lines
• 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.
• Wirings other than the above specifications or incorrect wirings may cause the fault or malfunction.

Others
• Wiring should be carried out after the power supply to the PLC was turned off.
• Also turn of the power supply when the control unit, expansion units and various cassettes are
connected. If they are connected during the power supply is on, it may cause the fault or malfunction.

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.

Dialog box of PLC Configuration setting

Settings of Hold area/Non-hold area

- The settings of the operation memory area such as data registers 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.

5-14
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 five minutes.
Charge the built-in capacitor to retain the contents of the memory during the replacement of the battery.
2. Turn off the power supply.
When the power is off, supply the power to the control unit for more than five minutes to charge the built-
in capacitor to back up the memory during the replacement of the battery.
3. Remove the expansion cover located at the surface of the control unit.
4. Remove the used battery.
5. Install a new battery within two minutes after turning off the power.
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.

5.7.4 Lifetime and Time for Replacement of Backup Battery

Battery lifetime
Type of control unit Battery lifetime Suggested replacement interval
L40, L60 4.6 years or more 7 years
Note1) The battery lifetime is the value when no power at all is supplied.
Note2) Note that the lifetime 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 if 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. Create a program to
announce errors to the outside as necessary.
- 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 five minutes before replacing the battery.
- Special internal relays R9005 and R9006 will be on when a battery error is detected regardless of the
setting of system register No.4.

5-15
5.8 Safety Measures

5.8.1 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.
Startup sequence
The PLC should be operated after all 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 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.
The terminal block cover must be used for preventing electric shock.

5.8.2 Momentary Power Failures

Operation of momentary power failures
- If the duration of the power failure is less than 10 ms, the FP-X0 control unit continues to operate. If the
power is off for 10 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.)
- Although the duration of the power failure for the expansion FP0 adapter is 10 ms, judge the
permissible time for the system after confirming the permissible duration of the power failure for the
DC power supply that supplies power to the expansion FP0 adapter. (Supply the power to it from the
service power supply for the input of the FP-X0 control unit.)
- When using the expansion unit with a built-in power supply (E30, expansion FP0 adapter), depending
on the duration of the momentary power failure, either one unit may be without electricity momentarily
and the I/O verify error may occur. In that case, turn off the power supply and then turn on again.

5.8.3 Protection of Output Sections

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.

PC(PLC) link COM port (RS485 port) L40MR, L60MR only
MODBUS RTU COM port (RS485 port) L40MR, L60MR only

6.1.2 Computer Link

- Computer link is used for communication with a computer connected to the PLC. Instructions
(command messages) are transmitted to the PLC, and the PLC responds (sends response messages)
based on the instructions received.
- A proprietary MEWNET protocol called MEWTOCOL-COM is used to exchange data between the
computer and the PLC.
- The PLC answers automatically to the commands received from the computer, so no program is
necessary on the PLC side in order to carry out communication.

6.1.3 General-purpose Serial Communication

- With general-purpose serial communication, data can be sent back and forth between an external
device connected such as an image processing device and a bar code reader.
- Reading and writing of data is done using a ladder program in the FP0R, while reading and writing of
data from an external is handled through the data registers.

6-2
6.1.4 PC(PLC) Link
- The FP-X0 supports the link system that connects the PC(PLC) link corresponding to the MEWNET-W0
(max. 16 units) with the twisted pair cables.
- 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).

6.1.5 Modbus RTU

Function overview
- The Modbus RTU protocol enables the communication between the PLC and other devices compatible
with Modbus RTU. (Such as our KT temperature control unit and FP-e)
- Communication is performed when the master unit sends instructions (command messages) to slave
units and the slave unit returns responses (response messages) according to the instructions.

6.4 Computer Link

6.4.1 Overview
- Computer link is used for communication with a computer connected to the PLC. Instructions
(command messages) are transmitted to the PLC, and the PLC responds (sends response messages)
based on the instructions received.
- A proprietary MEWNET protocol called MEWTOCOL-COM is used to exchange data between the
computer and the PLC.
- The PLC answers automatically to the commands received from the computer, so no program is
necessary on the PLC side in order to carry out communication.

- 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.

MEWTOCOL master function (For L40MR, L60MR types only)

- This function is to carry out the communication on the master side (side that 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. Example) PLC, temperature control unit, eco-power meter, image processor

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.

Note:
It is necessary to set the system register of the communication port to the computer link for using this
function.

6-7
6.4.2 MEWTOCOL Slave Function
Outline of operation

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. On the computer side, the execution result of the command can be confirmed by
the transmitted response.

MEWTOCOL-COM sketch
- Communication is performed based on the communication procedure of MEWTOCOL-COM.
- Data is sent/received 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.

6-8
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. The number of characters that can be sent in one frame differs depending on the start code.
Type of header No. of characters that can be sent in 1 frame Types
% Max. 118 characters FP-X0 all types
< Max. 2048 characters L40, L60
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. The unit number of the
PLC is specified by the system register.
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 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).

Note: When writing

- The method for writing text segments in the message varies depending on the type of command.
- If there are many characters to be written, they may be divided and sent as several commands, if there
are many characters in the value that was loaded, they may be divided and several responses sent.

6-9
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 a "<" (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. If the processing is not completed
successfully, an error code will be stored here, so that the content of the error can be checked.

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: When reading

- 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 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 of computer link

- 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. No communication program is required on
the PLC side. (Specify the communication format only by the system register.)
- 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.

6.5 General-purpose Serial Communication

6.5.1 Overview
- In general-purpose serial communication, data is sent and received over the communication port 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 communication port by means of
PLC programs and 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 PLC and an external device.

Sending data Receiving data

Data to be transmitted from the PLC is stored in Data received from the communication port is
the data register used as the send buffer (DT). stored in the receive buffer specified in the system
When F159(MTRN) is executed, the data is output register, and the "reception done" flag goes on.
from the communication port. Data can be received whenever the "reception
done" flag is off.

- The terminator specified in the system register is - When data is being received, the "reception
automatically added to the data that has been done" flag is controlled by the F159(MTRN)
sent. instruction.
- No terminator is included in the stored data.

6-17
6.5.2 Programming Example of General-purpose Serial Communication
The F159(MTRN) instruction is used to send and receive data via the specified communication port.

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 (K0 and K1 only)

Sending 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 start code and end code automatically attached.
- 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 communication port.

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

Binary communication
- Selecting “STX not exist” for the header and “None” for the terminator in the general-purpose serial
communication enables the binary communication.
Sending data: Sends the data of bytes to be specified.
Receiving data: Check the No. of bytes received before the process. At that time, the reception done
flag does not work.

6-18
Data to be sent/received with PLC
Remember the following when accessing data in the 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. When the terminator has been set to “None”,
the “reception done” flag does not work.
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 again.
- 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 an external device.
1. Data sent using the F95 (ASC) instruction should be converted to ASCII code data.

2. If DT100 is being used as the start address of 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.

6-19
6.5.3 Sending Data
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 communication 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 the
communication 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 the communication port using the F159 (MTRN) instruction.
Explanatory diagram

6-20
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.

Operation when sending data

When the execution condition of the F159 (MTRN) instruction turns on and the “transmission done” flag
R9039 is on, operation is as follows:
1. [N] is preset in [S]. The "reception done" flag R9038 is turned off, and the reception data number is
cleared to zero.
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 turns off.
- If system register No.413 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 is automatically added to the end of the
data.

3. When all the specified quantity of data has been transmitted, the S value is cleared to zero and the
"transmission done" flag R9039 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 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, do not add the header
to the transmission data. The header is added automatically.

6-21
6.5.4 Receiving Data
Data input from the communication 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)

DT200 to DT204 are used as the receive buffer.
System register settings are as follows:
- System register 416: K200
- System register 417: K5

Sample program for receiving data

10-byte data received in the receive buffer through the communication port 1 are copied to DT0.

The program described above is executed in the following sequence.

1) The data sent from external devices is stored in the receive buffer.
2) The “reception done” contact R9038 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 clear the number of received bytes and to
turn off the reception done” contact R9038. The system is now ready to receive the next data.
(The data in the receive buffer is not cleared.)
Explanatory diagram

6-22
Data table
Data sent from an external device connected to the communication port is stored in the data registers
that have been set as the receive buffer.
- Data registers are used 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.

Operation when receiving data

When the “reception done” flag R9038 is off, operation takes place as follows when data is sent from an
external device. (The R9038 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 turns on. Reception of any
further data is prohibited. When the terminator has been set to “None”, the “reception done” flag does
not turn on. Check the number of received bytes to judge whether the reception has completed or not.
3. When an F159 (MTRN) instruction is executed, the “reception done” flag R9038 turns off (except the
case when the terminator has been set to “None”), 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: on, reception prohibited)
3. Process received data
4. Execute F159 (MTRN) (R9038: off, reception possible)
5. Receive subsequent data

Prepare for reception

- The “reception done” flag R9038 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.

Note:
Be aware that the “reception done” flag R9038 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.

6-23
6.5.5 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 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, the “reception done” flag R9038 and the
“transmission done” flag R9039 goes off.
- Duplex transmission is disabled while F159 (MTRN) is being executed. The “transmission done” flag
R9039 must be observed.
- Reception stops if the error flag R9037 goes on. To resume reception, execute the F159 (MTRN)
instruction, which turns off the error flag.

Note:
Be aware that the “reception done” flag R9038 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.
6-24
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 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 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.

6-25
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 goes off.
- Duplex transmission is disabled while F159 (MTRN) is being executed. The “transmission done” flag
R9039 must be observed.

6-26
6.5.6 Changing Communication Mode Using F159(MTRN) Instruction
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”

R9032: The COM port mode flag turns on when general-purpose serial communication mode is selected.

6.6 PC(PLC) link Function (For L40MR, L60MR types)

6.6.1 Overview
PC(PLC) link function
- The FP-X0 supports the link system that connects the PC(PLC) link corresponding to the MEWNET-W0
(max. 16 units) with the twisted pair cables.
- 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).
- 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.
- The status of the link relays and link registers in any one PLC is fed back to all 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.

Operation of PLC link
Turning on a link relay contact in one PLC turns on the same link relay in all other
Link relay
PLCs on the same network.
Changing the contents of a link register in one PLC changes the values of the
Link register
same link register in all other PLCs on the same network.

Link relay
If the link relay L0 in unit No.1 is turned on, the status change is fed back to the ladder programs of other
units, and Y0 of the other units is output.

Link register
A constant of 100 is written to link register LD0 of unit no.1.
The contents of LD0 in the other units are also changed to a constant of 100.

6-32
6.6.2 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 SYS1
instruction or the system register.

Precautions on the unit number settings

- 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.
- 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.
- If fewer than 16 units are linked, the transmission time can be shortened by setting the largest unit
number in system register no. 47.
- The priority order for unit number settings is as follows;
1. SYS1 instruction
2. System registers

link.

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 be 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).

6-35
Example of allocation
The areas for PC(PLC) link are divided into send areas and receive areas. The link relays and link
registers are sent from the send area to the receive area of a different PLC. Link relays and link registers
with the same numbers as those on the transmission side must exist in the receive area on the receiving
side.

(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).

6-37
Partial use of link areas
In the link areas available for PC(PLC) link, link relays with a total of 1024 points (64 words) and link
registers with a total of 128 words can be used. This does not mean, however, that it is necessary to
reserve the entire area. Parts of the area which have not been reserved can be used as internal relays
and internal registers.

6-38
 Note: Precautions When Allocating Link Areas
If a mistake is made when allocating a link area, be aware that an error will result, and communication
will be disabled.

Avoid overlapping send areas

- When sending data from a send area to the receive area of another PLC, there must be a link relay and
link register with the same number in the receive area on the receiving side.
- In the example shown below, there is an area between No.2 and No.3 which is overlapped, and this will
cause an error, so that communication cannot be carried out.

6.6.5 Setting the Largest Unit Number for 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).

[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.
- If fewer than 16 units are linked, the transmission time can be shortened by setting the largest unit
number in system register no.47 (in system register no.57 for PC(PLC) link 1).
- 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.

Setting PC(PLC) link switching flag

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 link relays and registers are used.

6.6.6 Monitoring When Using PC(PLC) Link
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)
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.
Relay no. R906F R906E R906D R906C R906B R906A R9069 R9068 R9067 R9066 R9065 R9064 R9063 R9062 R9061 R9060

Key Point: Monitoring the PC(PLC) link status

Using a programming tool, the PC(PLC) link status items, such as the transmission cycle time and the
number of times that errors have occurred, can be monitored.

Using FPWIN GR: Select [Status Display] under [Online] in the menu. Click the [PC link] button after the
[Status Display] screen is shown.

Using FPWIN Pro: Select [PLC Link Status] under [Online] in the menu.

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

6-41
6.6.7 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.

○1 Ts (transmission time per station)

Ts = scan time + Tpc (PC(PLC) link sending time)

Tpc = Ttx (sending time per byte) x Pcm (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

○2 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)

○3 Tso (master station scan time)

This should be confirmed using the programming tool.

○4 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

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
6-42
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 the transmission cycle time even if there are one or
more stations that have not been added to the link.

6-43
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)

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:
If there are any units that have not been added to the link, the setting should not be changed if 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.)

6-44
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)

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:
The setting should not be changed if 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 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.)

6.7 MODBUS RTU Communication (For L40MR, L60MR
types)

6.7.1 Overview of Functions

- The MODBUS RTU protocol enables the communication between the FP-X0 and other devices
(including our FP-X, FP-e, Programmable display GT series and KT temperature control).
- 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.
- Enables the communication between the devices of max. 255 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 FP-X0 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 unit is used as a slave unit.

High-speed Counter, Pulse Output and
PWM Output Functions

7-1
7.1 Overview of Each Functions

7.1.1 Three Pulse Input/Output Functions

There are three pulse I/O functions built into the FP-X0.

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.

7-2
7.1.2 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.

Setting the system register

For using the pulse output function, it is necessary to set the system register No. 402.

7.4.2 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 (sign) 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 (sign) signals are ON.

7.4.5 Forced Stop, Deceleration Stop (F0) Instruction
Pulse output control instruction (F0)
- Forced stop and deceleration stop is executed by F0(MV) instruction in combination with the special
data register DT90052. Once this instruction is executed, the settings will remain until this instruction is
executed again.
[Example] Performing the forced stop of pulse output.
For CH0 For CH1

Note:
- Performing a forced stop may cause the elapsed value at the PLC output side to differ from the elapsed
value at the motor input side. Therefore, you must execute a home return after pulse output has
stopped.
- When executing the forced stop (pulse output stop) with the pulse output control instruction (F0), the
operations being executed with various instructions are cancelled and the pulse output is immediately
stopped. When the forced stop request flag (bit3 of DT90052) is on, instructions cannot be executed.
- When executing the deceleration stop with the pulse output control instruction (F0), the operations
being executed with various instructions are cancelled and the deceleration operation starts. When the
deceleration stop request flag (bit5 of DT90052) is on, instructions cannot be executed. As for the data
table control instruction (F174), the operation is like that of the forced stop.
- After the execution of the forced stop or deceleration stop, pulses are not output unless the execution
condition of each pulse output instruction (F171 to F177) changes from OFF to ON.

7-19
7.4.6 Elapsed Value Read and Write (F1) Instruction
Elapsed value read and write instruction (F1)
- This instruction is used to read and write the pulse number counted by the pulse output control.
- Specify this F1 (DMV) instruction in combination with the pulse output elapsed area after the special
data register DT90400.
- When executing the F1 (DMV) instruction with DT90400, the elapsed value is stored as 32-bit data in
the combined area of the special data registers DT90400 and DT90401.
- The elapsed values can be read or written with this F1 (DMV) instruction only.

Example 1: Writing the elapsed value

Set the initial value K3000 in the pulse output
CH0.

Example 2: Reading the elapsed value

Read the elapsed value of the pulse output
CH0 to DT100 and DT101.

Elapsed value area

Channel No. Pulse output elapsed value area
CH0 DT90400 to DT90401
CH1 DT90410 to DT90411

Note:
The elapsed value area varies during scanning. Replace it with an arbitrary data register at the beginning
of the program as necessary in cases such as using it several times in the program.

7.4.7 JOG Operation Instruction (F172)
- This instruction is used to output pulses according to a specified parameter when the trigger (execution
condition) is on.
- When the trigger (execution condition) turns off, deceleration is performed within a specified
deceleration time. However, if the trigger turns on again, acceleration is performed up to the target
speed again.
- When the deceleration stop is requested by the F0 instruction during the pulse output, the deceleration
stop is performed.
- There are two kinds of control method, which are type 0 and type 1.

Operation modes of JOG operation

There are two operation modes for the JOG operation, which are type 0 and type 1. Those operation
specifications for the specified target value differ.

Type 0
Regardless of the settings for the target value, the JOG operation is performed when the trigger is on.

Type 1
Even if the trigger is on, the deceleration stop is performed according to the settings of the target value.

7-21
The explanation below shows the case that pulses are output from Y0 when using forward rotation and
Y1 when using reverse rotation with the following conditions; Initial speed: 1 kHz, Target speed: 7kHz,

7.4.8 Home Return Instruction (F177)
- When the trigger (execution condition) turns on, the home return is performed according to a specified
data table.
- On the completion of the home return, the elapsed value area is reset to "0".
- When the deceleration stop is requested by the F0 instruction during the pulse output, the deceleration
stop is performed.
- Even when the home input is on, the pulse output starts by the execution of this instruction.
- When the near home input turns on during acceleration, the deceleration operation starts.
- There are two kinds of control method, which are type 0 and type 1.

Operation modes of Home return operation

There are two kinds of operation modes, which are type 0 and type 1.

Type 0
The home input is effective regardless of whether there is a near home input, whether deceleration is
taking place, or whether deceleration has been completed. Also, the home return can be performed
without the near home input.

Type 1
In this mode, the home input is effective only after deceleration (started by near home input) has been
completed. If the leading edge of home input (off to on) is detected during the operation at a creep speed
after the deceleration operation, the pulse output stops.

7-24
The explanation below shows the case that home return is performed with the following conditions; Initial
speed: 1 kHz, Target speed: 5 kHz, Creep speed: 500Hz, Acceleration time: 300 ms, Deceleration time:

Precautions during programming
- Specify the composite speed to make the component speed of each axis be 6Hz or more.
- Set the composite speed (Initial speed) to be 30 Hz or less.
- For the linear interpolation instruction (F175), specify the same value for the acceleration time and
deceleration time.
- To perform the operation only to the negative direction in the incremental mode, set the target value to
zero.
- To perform the operation only to the negative direction in the absolute mode, set the target value to the
same as the current value.

7-33
7.4.12 Pulse Output Instruction Flag
- Note that there are the following restrictions on using each function of the pulse output
Allocation and role of pulse output instruction flag
- When a pulse output instruction (F171/F172/F174/F175/F177) or PWM output instruction (F173) is
executed and pulses are being output, the pulse output instruction flag of the corresponding channel is
ON. No other pulse output instructions can be executed if this flag is ON.
- The pulse output instruction flags are allocated to each channel.

Channel Pulse output instruction flag

CH0 R9120
CH1 R9121
Operation of pulse output instruction flag
- The pulse output instruction flags vary even during scanning. Replace them with internal relays at the
beginning of the program when using them several times in the program.

7.4.13 Common Precautions for Pulse Output Instructions

- Note that there are the following restrictions on using each function of the pulse output
Precautions when using instructions in PULSE+SIGN mode (Common to F171, F172, F175, F177)
- When each instruction is executed, pulses are output approx. 300µs after the direction signal has been
output; the motor drive characteristics are simultaneously taken into consideration.
Stop by pulse output control instruction (F0) (Common to F171, F172, F174, F175, F177)
- Performing a forced stop may cause the output count value in the elapsed value area to differ from the
input count value at the motor side. Therefore, you must execute a home return after pulse output has
stopped.
- When executing the emergency stop (pulse output stop) with the pulse output control instruction (F0),
the operations being executed with various instructions will be cancelled and the pulse output will be
immediately stopped. When the emergency stop request flag (bit 3 of DT90052) is on, instructions
cannot be executed.
- When executing the deceleration stop with the pulse output control instruction (F0), the operations
being executed with various instructions will be cancelled and the deceleration operation will start.
When the deceleration stop request flag (bit 5 of DT90052) is on, instructions cannot be executed. As
for the data table control instruction (F174), the operation is like that of the emergency stop.
- After the execution of the emergency stop or deceleration stop, pulses are not output unless the
execution condition of each pulse output instruction (F171 to F177) changes from OFF to ON.
Specification of initial speed and speed error (Common to F171, F172, F174, F175, F177)
- Note that there are the following characteristics according to the initial speed specified with each
instruction.
(1) When the initial speed is 1 Hz or higher, and lower than 46 Hz, the control can be performed up to 10
kHz.
(2) When the initial speed is 46 Hz or higher, and lower than 184 Hz, the control can be performed up to
the maximum frequency.
(3) When the initial speed is 184 Hz or higher, the control can be performed up to the maximum
frequency. The speed error will be smallest.
Control code and quick start (Common to F171, F172, F175)
- When "Calculation only" is specified in the digit to set the output of the control code of each instruction,
the pulse output is not performed.
- Instructions can be quickly started when executing them for the same channel and with the same
parameter after executing calculation only. The quick start is enabled when the parameters are the
same except output.
Duty cycle of pulse output (Common to F171, F172, F174, F175, F177)
- Pulses are output with a 25% duty cycle.

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 it matches the appointed time.

9.2 Sampling Trance Function (For L40 and L60 types)

9.2.1 Overview
- The sampling trace function is available for the FP0R. Using this function enables to take samplings
and record (accumulate) the state of arbitrary 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 by [Time chart monitor] 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.
Number Name Operation
F155 (SMPL) sampling instruction
F156 (STRG) Sampling stop trigger instruction
R902C Sample point flag OFF = Sampling by instruction
ON = Sampling at regular time intervals
R902D Sampling trace end flag When sampling trace starts = 0 stops = 1
R902E Sampling trigger flag Turns on when sampling stop trigger is on.
R902F Sampling enable flag Turns on when sampling operation starts.
DT90028 Interval of sampling trace K0 = For sampling by instruction
K1 to K3000 (10 ms to 30 seconds) For
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 executed, 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 sampling can be
executed in one scan.
- Timing for the execution of the F155 (SMPL) instruction can be set by the ladder sequence.
- 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 number of delays,
and then stop the sampling operation.
- Once the sampling operation stops, the data will be automatically retrieved by the tool software and will
be indicated in a time chart.
- For the initial settings (number of samples: 1000, number of delays: 100), the number of samples
before and after the trigger point is 900 and 1000 respectively.

9.2.3 How to Use Sampling Trace

1. Sampling at regular time intervals

1) Register the bit/word device to be monitored by the time chart monitor function of FPWIN GR.
2) Specify the sampling configurations.
Set the mode of the sampling configurations to "TRACE".
Set the sampling rate (time).

3) Start monitoring. Start with the button.

9-5
2. Sampling by instruction
1) Register the bit/word device to be monitored by the time chart monitor function of FPWIN GR.
2) Specify the sampling configurations.
Set the mode of the sampling configurations to " TRACE ".
Set the sampling rate (time) to 0.

3. Read data by trigger

1) Stop sampling by stopping monitoring the trace that has been started in the above procedure 1 or 2
on the time chart display of FPWIN GR. The data will be indicated in the time chart.
Stop monitoring. (Stop with the button, stop by the "Trigger Break" in the menu, or stop by the F156
instruction.)

9-6
9.3 Time Constant Processing
The input time constants for 16 points of the CPU input X0 to XF can be set by the system registers 430
to 437.
If this setting is specified, an operation like the equivalent circuit below will be performed.
By the setting, the noises or chattering of input will be removed.

CXn = Input signal of Xn contact

Xn = Image memory of input Xn

Note:
- The input signal of X contact is retrieved at the timing of the normal I/O update.
- If the partial update instruction is executed for the input in the time constant processing, the time
constant processing will be invalid, and the input status at the time will be read out and set.
- The time constant processing can be performed for the input other than X0 to XF (add-on cassettes or
expansion units) by the F182 (FILTR) instruction.
- The timer instruction is not used for the timer processing in this equivalent circuit.
- The time constant processing is invalid when the high-speed counter, pulse catch or interrupt has been
specified.

9.4 P13 (PICWT) Instruction
Data registers of 32765 words can be stored and used in the built-in ROM (F-ROM data area)
control unit using the P13 (PICWT) instruction.

Note the followings for the use:

1. Restrictions on the number of writings

Writing can be performed within 10000 times. If writing continues for more than that, the correct
operation cannot be guaranteed.

2.The power supply turns off when the P13 (PICWT) instruction is being executed.
If the power supply turns off during this instruction is being executed, the hold type area may not be kept.
(Also, when the power is shut off during rewriting in the RUN mode, the same event may occur.)

an error.

10-2
10.2 Troubleshooting

10.2.1 If ERROR LED is Flashing

Condition: The self-diagnostic error occurs
Procedure 1
- Check the error contents (error code) using the programming tool.
- With the FPWIN GR, 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.
- To display the status display dialog
box again, select “Status Display”
under “Online” on the menu bar.

Note) The above screen shows the case when using the FP0R.

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.

<For error code is 20 or higher>

- Condition
A self-diagnostic error other than a syntax error has occurred.
- Operation
Use the programming tool in PROG. mode to clear the error.

<For error code is 42 (1)>

- Condition
The expansion unit that had been connected when the power supply of the control unit was turned on is
disconnected or the expansion unit has powered off.
- Operation 1
Turn off the power supply of the control unit, and connect the expansion unit and add-on cassette.
- Operation 2
Turn on the power supply of the expansion unit.

10-3
<For error code is 42 (2)>
- Condition
A temporary blackout such as a momentary power off occurred and the power supply of the expansion
unit was turned off.
- Operation 1
Once the power supply of the expansion unit is restored, the control unit will be automatically reset and
restarted.

<For error code is 43>

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 the
contents of the operation memory except hold type data will be cleared.
- 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 ERR. LED is ON

Condition: The system watchdog timer has been activated and the operation of PLC has been
activated.

Procedure 1
Set the mode selector of PLC from RUN to PROG. mode and turn the power off and then on.
- If the ERR. LED is turned on again, there is probably an abnormality in the control unit. Please contact
your dealer.
- If the ERR. LED flashes, refer to chapter 10.2.1.

Procedure 2
Set the mode selector from PROG. to RUN mode.
- If the ERR. LED is turned on; the program execution time is too long. Check the program.

10.3 Operation Errors

10.3.1 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 area 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.

10.3.2 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 FPWIN GR
1. Set the mode of the CPU to RPOG.
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.
Using FPWIN Pro
1. Change the mode to offline.
2. Select "Action on error" from the system register table of the project navigator.
3. Change the setting of No. 26.

10-7
10.3.3 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.
- When using FPWIN GR, select "Online" -> "Status Display" in the menu bar.
Execute "Clear Error".
- When using FPWIN Pro, select "Monitor" -> "PLC Status". Press the "Error Clear" button.
- 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.

10.3.4 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. However, it may exceed the
addressable range of the data register depending on the data in I0. If the value exceeds the range, 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 devisor of a division instruction is “0”.

<Example>
In this case, if the content of DT100 is "0", an operation error will occur.

Chapter 11
Precautions During Programming

11-1
11.1 Use of Duplicated Output (Double Coil)

11.1.1 Duplicated Output (Double Coil)

What is duplicated output (double coil)?
- 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 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 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
enabled.
- 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.
<Example> 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 results of the operation.
<Example> 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 Instructions of Leading Edge Detection Method

11.2.1 Instructions of Leading Edge Detection Method

Instructions using the leading-edge detection operation
1. DF (leading edge differential) instruction
2. Count input for CT (counter) instruction
3. Count input for F118 (UCD up-down counter) instruction
4. Shift input for SR (shift register) instruction
5. Shift input for F119 (LRSR left-right shift register) instruction
6. NSTP (next step) instruction
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
cases, 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. 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

11-4
11.2.2 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

11-5
<Example 2> CT (counter) instruction

11-6
11.2.3 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

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

11-7
11.3 Precautions for Programming
Programs which are not executed correctly
When combinations 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.

<Example 1> When X1 was on prior to X0, Y0 will not be on even if X0 becomes on.

<Example 2> TMX5 will activate if X1 becomes on regardless of 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.

Examples in which the above programs are rewritten correctly

<Program in which the example 1 is rewritten>

<Program in which the example 2 is rewritten>

<Program in which the example 3 is rewritten>

11-8
11.4 Rewrite Function During RUN

11.4.1 Operation of Rewrite During RUN

How operation of rewrite during RUN is performed
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

1. External output (Y) is held.
2. External input (X) is ignored.
3. The timer (T) stops the clock.
4. Rise and fall changes in the inputs of differential instructions (DF), counter instructions (CT), and
left/right sift registers are ignored.
5. Interrupt functions are stopped.
6. Internal clock relays (special internal relays) are also stopped.
7. 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 complete flag

The rewrite during RUN complete 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.

11-9
11.4.2 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.

11-10
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. Subroutine instructions (SUB/RET)
3. Interrupt instructions (INT/IRET)
4. JP/LBL
5. LOOP/LBL
6. MC/MCE
Also, rewriting is not possible during RUN in case of other syntax error.

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.
Operation after the completion of
Instruction No. Name

11.5 Processing During Forced Input and Output

11.5.1 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.
- As for contacts not specified, the on/off state will be read according to the input status from the input
device.

2. Processing of external output (Y)

- Regardless of the state of the result of operation, forced on/off will take precedence at a contact
specified for forced input/output in the above procedure A. At this time, the area of output Y in the
operation memory will be forcibly 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

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.

14.1 System Registers / Special Internal Relays / Special
Data Registers

14.1.1 System Registers

Precaution 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 registers 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 14) (For L40 and L60 types only)
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 20, 23 and 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 PC(PLC) link settings (System registers 40 to 47, 50 to 55, and 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 405)

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 415, 420, 421)
Set these registers when the Tool port and COM ports are to be used for computer link, general-purpose
serial communication, PC(PLC) link, and modem communication.

8. Input time constant settings (System registers 430 to 437)

Changing the input signal width to be loaded enables to prevent the malfunctions caused by chattering
or noises.

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, the system registers after No. 400 become effective when the mode is changed from PROG.
mode to RUN. Regarding 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

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.

14.4 Table of Error codes
 Difference in ERROR display
There are differences in the way errors are displayed depending on the model.
Model Display Display method
FP2, FP2SH LED ERROR Continually lit
FPΣ,FP0, FP0R, FP-X LED ERROR/ALARM Flashes/continually lit
FP-e Screen display ERR. Continually lit

 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 appropriate 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 switching 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.

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
abnormal 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 content of error and the
system register setting.
- The error codes will be stored in the special data register DT90000.
- In the case of operation error, the error address will be stored in the DT90017 and 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 self-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.

Order Placement Recommendations and Considerations

  The Products and Specifications listed in this document are subject to change (including

  Panasonic Industrial Devices SUNX is consistently striving to improve quality and reliability.
  However, the fact remains that electrical components and devices generally cause failures
  at a given statistical probability. Furthermore, their durability varies with use environments
  or use conditions. In this respect, check for actual electrical components and devices under
  actual conditions before use. Continued usage in a state of degraded condition may cause the
  deteriorated insulation. Thus, it may result in abnormal heat, smoke or fire. Carry out safety
  design and periodic maintenance including redundancy design, design for fire spread prevention,
  and design for malfunction prevention so that no accidents resulting in injury or death, fire
  accidents, or social damage will be caused as a result of failure of the Products or ending
  life of the Products.

  sure standards, laws and regulations in case the Products are incorporated to machinery, system,
  apparatus, and so forth. With regard to the mentioned above, confirm the conformity of the
  Products by yourself.
