conditions of the external noise, it may be necessary to ground externally, or better not to ground the
shielding.
• Do not have the analog input wiring close to AC wires, power wires, or load wires from sources other
than the PLC.
• The terminals marked with a dot on the input and output terminal blocks are not to be used. However,
they may be connected to circuits internally, so be sure not to connect any wiring to them.

Setting I/O Range and I/O Allocation
4.1 I/O Allocation

4.1.1 Setting the Analog Input Range

How to set the input range
Set the range setting switch on backside of the unit as described in the table below. The range for all the
channels will be set at once.
If you use different input ranges together, then set the range setting switch to “Enable setting by
software” and set the ranges by the shared memory.

Setting of range setting switch

Note) The range setting switch for FP2-AD8VI is a octal switch. The switches No. 6 to 8 must be used
being switched off. If they are on, it does not operate properly.

Default setting
All the switches are off.

Especially note:
Do not set the range setting switch to “not used”. If setting to “not used”, the unit will not operate properly.

For setting different ranges for each input channel

Set the range for each channel respectively by ladder programs.
Always set the range setting switch as below.

Reference: <12.3.1 Shared Memory of Analog Input Unit>

4-2
4.1.2 Setting the Analog Output Range
How to set the output range
The analog output range setting can only be performed by the range setting switch. At the analog output
units, use the range setting switches 1 to 4 to set the range for each channel.

Default setting
All the switches are off.

Especially note:
For the analog output unit, be sure to have the range setting switches 5 and 6 set to off. If setting to on,
the unit will not operate properly.

4.2 I/O Allocation and Slot Numbers

4.2.1 Occupation I/O Areas and I/O Allocation

During sequence program processing with the FP2, the analog input and output data is allocated to the
I/O (X, Y) and refreshed.
The analog input signal for one channel is handled in units of 16 points of the X contact.
The analog output signal for one channel is handled in units of 16 points of the Y contact.
The I/O allocation for the analog input and output data is as shown in the table below.

Analog input unit Occupation number of points: 128 points (Input: 128 points)
Channel FP2 I/O number Programming tool software
Ch0 WX(n): X(n)0 to X(n)F
Ch1 WX(n+1): X(n+1)0 to X(n+1)F
Ch2 WX(n+2): X(n+2)0 to X(n+2)F
Ch3 WX(n+3): X(n+3)0 to X(n+3)F
Analog input 128SX
Ch4 WX(n+4): X(n+4)0 to X(n+4)F
Ch5 WX(n+5): X(n+5)0 to X(n+5)F
Ch6 WX(n+6): X(n+6)0 to X(n+6)F
Ch7 WX(n+7): X(n+7)0 to X(n+7)F

Analog output unit Occupation number of points: 64 points (Input: 64 points)

Channel FP2 I/O number Programming tool software
Ch0 WY(n): Y(n)0 to Y(n)F
Ch1 WY(n+1): Y(n+1)0 to Y(n+1)F
Analog output 64SY
Ch2 WY(n+2): Y(n+2)0 to Y(n+2)F
Ch3 WY(n+3): Y(n+3)0 to Y(n+3)F

Note:
• The I/O number shown by an “n” in the table above is determined according to the installed slot
position and the I/O allocation for other units.
• The occupation number of points remains unchanged even if the number of channels to use has been
reduced in the shared memory setting.

4-4
4.2.2 Confirmation of I/O No. Allocation
I/O numbers and slot numbers are necessary to generate programs. Those numbers vary depending on
the installation position to the backplane. Confirm they are as per design.
Confirm the occupation I/O areas for all the units installed between the CPU unit and the analog unit.
The next number is allocated for the analog unit as I/O area.

Example:
When installing the analog input unit next to three 16-point I/O units.

Example:
When installing the analog output unit next to three 16-point I/O units.

Note:
• If there are any blank slots between the CPU unit and the analog unit, confirm whether the I/O areas
have been allocated for the blank slots.
• The areas for 16 points are automatically allocated for each blank slots during “I/O mounting allocation”
or “automatic allocation”
• When using the two-module type CPU unit, also confirm the I/O area allocated by the unit built in the
CPU units.

4-5
4.2.3 Slot Numbers
Slot numbers are necessary to set various items by programs for the analog unit.

Analog input/output unit

The slot number for the unit is determined depending on the installation position on the backplane.

When installing on the backplane of the CPU side

The right-hand slot of the CPU unit is counted as “0”.

4-6
 Note:
When using the two-module type CPU unit, the slot No. “0” is allocated to the unit built in the CPU.

When installing on the backplane which the CPU unit with the S-Link is mounted, count the slot numbers
for the unit built in the CPU unit as “0, 1”.

When installing on the backplane of the expansion side

Count the right-hand slot number of the power supply unit on the backplane of the expansion side as
“16”.

• The preparation completion flag in the shared memory area No. 10 changes from off to on only when
the power supply turns on. The flag does not change when switching the RUN mode/PROG. mode.
• The values of the shared memory right after turning the power supply on are preset to the default
values specified for every memory area numbers.

When turning the power on to off

The value set in the shared memory of the unit is cleared.

5.1.2 Analog Output Operation

When turning the power off to on
• The voltage (approx. –10V) may be output momently (for approx. 200 ms) from the output terminal of
the analog output unit when the power supply of FP2/FP2SH turns on/off.
If it becomes a problem on the system, take appropriate measures, such as delaying the timing of the
power activation of connected external devices from the power activation of the PLC.
• The values of the shared memory right after turning the power supply on are preset to the default
values specified for every memory area numbers. Program to execute the initial setting program after
turning the power on if necessary.
• The analog output values are output according to the values written in the output relay area (WY). After
turning the power on, the program is executed and the values equivalent to zero for WY are output until
the data is written in the output relay area (WY).

Example: For the range of 0 to 20 am

The value 0 [am] equivalent to the digital value K0 is output.

When turning the power on to off

The value set in the shared memory of the unit is cleared.

Basics of the analog input operation
1) The data read into the input part are converted to the digital values within the analog unit successively.
Note) The converted digital values differ depending on the range settings.
2) The converted digital values are stored in any desired area by the user program of the CPU unit
reading appropriate input relay area WX.
Note) The area numbers differ depending on the installation positions.

7.2 Timing for Reading Data
Input conversion processing time for input unit
Conversion time differs depending on the used ranges and number of channels.
The conversion time can be shorten for the number of channels where the conversion is not executed by
using the execution/no execution setting.

When specified to execute the conversion for four channels

Converts in order of base processing→ch0→ch1→ch2→ch3→base processing→….
The base time is fixed at 400 µs regardless
of the number of conversion channels.

Timing for reading data in the CPU unit

• The digital value converted in the analog unit is read into the CPU unit at the time the I/O is refreshed.
• Since the conversion within the analog unit is not synchronized with the I/O refresh for the CPU unit,
The latest data will be read into the memory for operation of the CPU unit at the time the I/O refresh is
performed.

• The converted digital values can be offset in programs using the incremental or decremental instruction

Note:
• The ranges for the converted values differ depending on the used ranges.
• The number of input contacts and specified slot numbers differ depending on the installation positions
of the units.
• Set offset values for each channel. The offsets may differ for each channel even if the analog input

For the input channels of the thermocouple input range and R.T.D (resistance thermometer device) input
range, you can detect broken wires in the input wiring of the temperature sensor for each channel using
the broken-wire detection flag.
Once a broken wire detected, a relevant bit in the shared memory address 42 for the unit turns on, and
the analog input data becomes 20000.
The shared memory address 42 is read and used by the user program as necessary.

Note:
For the broken wire detection in the three-wire resistance thermometer device input wiring, depending on
which wire breaks as shown below, there are situations where the broken wire detection cannot be
performed.

• Wire (A) connected to the A/+ terminal is broken: Broken wire detection is possible.
• Wire (B) and (C) connected to the B/- terminal and the V/b terminal are broken together: Broken wire
detection is possible.

• Only wire (B) connected to the B/- terminal is broken: Broken wire detection is not possible.
• Only wire (D) connected to the b terminal is broken: Broken wire detection is not possible.

Timing for analog output from analog unit

• Data is written into the analog unit as a data in the output relay area at the time the I/O for the CPU unit
is refreshed.
• Since the conversion within the analog unit is not synchronized with the operation of the CPU unit, the
latest data written from the CPU unit will be converted to the analog value and output.
The time taken for the analog unit to convert digital data differs depending on the used number of
channels and the used ranges.

 Address Conditions
When the PROG. mode changes to the RUN mode, all preparation completion flags for
all channels turn on as the setting has been done to execute conversion for all
channels. Once the no execution setting has been specified for each channel, the
10 applied bits in address 10 are in preparation.
If setting the range setting switch to “Enable setting by software”, the analog input
preparation completion flag for the address 10 does not turn on as the conversion will
not be performed until completing the range setting.
Writing by user program is not available.
10, 38, 42
Reading is always available.
16, 17, After changing the mode from the PROG to the RUN mode, writing by program is
22 to 37,39 available any number of times.
Writing by user program is available only once after the RUN mode.

12.3 Analog I/O Conversion Cycle Time
When setting the range for each analog I/O channel, the analog I/O conversion cycle time can be
calculated by the formula below.

• Analog input conversion cycle time (FP2-AD8VI)

Conversion cycle time
=conversion speed (0.5 ms) x number of input channels used + base time (0.4 ms)
(number of input channels set for execution of conversion
processing)

• Analog input conversion cycle time (FP2-AD8X,FP2-RTD)

Conversion cycle time
=conversion speed x number of input channels used
(number of input channels set for execution of conversion processing)

Note1) The total time of all channels set for execution of conversion processing.
Note2) When the thermocouple range and the R.T.D. range are mixed, the conversion cycle time for the
voltage range will get longer.

• Analog output conversion cycle time (FP2-DA4)

Conversion cycle time
=conversion speed (0.5 ms) x number of output channels used
(number of output channels set for execution of conversion
processing)
