Introduction
This chapter describes general information and specifications of the FC4A series MicroSmart analog I/O modules.
About the Analog I/O Modules
Analog I/O modules are available in 3-I/O types, 2-, 4-, and 8-input types, and 1- and 2-output types. The input channel
can accept voltage and current signals, thermocouple and resistance thermometer signals, or thermistor signals. The output
channel generates voltage and current signals.

END Refresh Type and Ladder Refresh Type
Depending on the internal circuit design for data refreshing, analog I/O modules are categorized into two types.
END Refresh Type
Each END refresh type analog I/O module is allocated 20 data registers to store analog I/O data and parameters for controlling
analog I/O operation. These data registers are updated at ever y end processing while the CPU module is running. WindLDR has
ANST macro to program the analog I/O modules.
The CPU module checks the analog I/O configuration only once at the end processing in the first scan. If you have changed the
parameter while the CPU is running, stop and restart the CPU to enable the new parameter.
Ladder Refresh Type
Each ladder refresh type analog I/O module can be allocated any data registers to store analog I/O data and parameters for controlling analog I/O operation. The data registers are programmed in the ANST macro. Analog I/O data are updated at the ladder
step following the ANST macro. Analog I/O parameters are updated when the ANST macr o is executed, so analog I/O parameters can be changed while the CPU is running.

Power Supply for Analog I/O Modules
When supplying power to the analog I/O modules, take the following considerations.
• Power Supply for END Refresh Type Analog I/O Modules
Use separate power supplies for the MicroSmart CPU module and END refresh type analog I/O modules. Power up the
analog I/O modules at least 1 second earlier than the CPU module. This is recommended to ensure correct operation of the
analog I/O control.
• Power Supply for Ladder Refresh Type Analog I/O Modules
Use the same power supply for the MicroSmart CPU module and ladder refresh type analog I/O modules to suppress the
influence of noises.
After the CPU module has started to run, ladder refresh type analog input modules perform initialization for a maximum
of 5 seconds. During this period, the analog input data have an indefinite value. Design the user program to make sure that
the analog input data are read to the CPU module after the analog input operating status has changed to 0 (normal operation). For the analog input operating status, see page 4-13.
Wiring Analog I/O Lines
Separate the analog I/O lines, particularly resistance thermometer inputs, from motor lines as much as possible to suppress
the influence of noises.

Data Register Allocation Numbers for Analog I/O Modules
Analog I/O modules are numbered from 1 through 7, in the order of increasing distance from the CPU module. Data registers are allocated to each analog I/O module depending on the analog I/O module number. END refresh type analog I/O
modules and ladder refresh type analog I/O modules have different data register allocation.
END Refresh Type Analog I/O Modules
Each END refresh type analog I/O module is automatically allocated 20 data registers to store parameters for controlling
analog I/O operation, starting with D760 through D779 for analog I/O module No. 1, up to D880 through D899 for analog
I/O module No. 7. When a maximum of seven analog I/O modules are not used, data registers allocated to the unused analog I/O module numbers can be used as ordinary data registers.
When a maximum of seven END refresh type analog I/O modules are mounted, data registers D760 through D899 are
allocated to analog modules 1 through 7 as shown below. The ANST macro is used to program data registers for the analog
I/O module configuration. The CPU module checks the analog I/O configuration only once when the CPU starts to run. If
you have changed the parameter while the CPU is running, stop and restart the CPU to enable the new parameter.
The END refresh type analog I/O module number starts with 1 next to the CPU module up to a maximum of 7.
The run-time program download and test program download cannot be used to change analog I/O parameters.
Note: Data registers allocated to the unused analog I/O module numbers can be used as ordinar y data registers.

Analog Input Minimum/Maximum Values
For analog input values, when Optional range is selected for the Data Type, designate the analog input data minimum and
maximum values which can be –32,768 through 32,767.
In addition, when using resistance thermometers (Pt100, Pt1000, Ni100, or Ni1000) with the Celsius or Fahrenheit Data
Type and the ×100 scale, select the analog input data minimum value from 0 or another value in the pull-down list. The
maximum value is changed automatically according to the selected minimum value.
Filter Value
The filter function is available for the ladder input type FC4A-J4CN1, FC4A-J8C1, and FC4A-J8AT1 only. Filtering
ensures smooth input of analog data into the CPU module. For the filtering function of analog input signals, see page 4-4.
Valid values are 0 through 255.
Thermistor Parameter
Thermistor parameters are enabled when selecting NTC thermistor for the analog input type of the FC4A-J8AT1. The
same parameters are specified for four channels: CH0 to CH3 and CH4 to CH7.
For NTC type thermistors, analog input data can be calculated from the following formula:
For PTC type thermistors, linearize the analog input data using the XYFS instruction.
Analog Input Data
The analog input signal is converted into a digital value within the range specified by the analog input data type and applicable parameters, and is stored to a data register allocated to analog input data. The analog input data register number is
shown under Data in the Configure Parameters dialog box.
END Refresh Type
The analog input signal is converted into a digital value and stored to a data register, such as D760 or D766, allocated to
analog input channel 1 or 2 on analog module number 1 through 7 depending on the mounting position.
The analog input data stored in the allocated data register is updated whether the CPU module is running or stopped. When
the CPU module is running, the update occurs at the END processing of every scan or 10 ms, whichever is longer. When
the CPU module is stopped, the update occurs every 10 ms.
Ladder Refresh Type
The analog input signal is converted into a digital value and stored to a data register determined by the data register number selected in the Configure Parameters dialog box of the ANST macro. The analog input data stored in the allocated data
register is updated when the RUNA instruction contained in the ANST macro is executed.
When a certain channel of a ladder refresh type analog input module is not used, data registers allocated to the unused
channel will store indefinite values if the values are read out of the analog input module. Do not use the allocated data registers for other purposes.
Only when the analog input status code is 0, the analog input data is assured. Make sure that a user program reads analog
input data only when the analog input status code is 0.
Analog Input Operating Status
The operating status of each analog input channel is stored to a data register allocated to analog input operating status.
While the analog input is operating normally, the data register stores 0. The analog input operating status data register
number is shown under Status in the Configure Parameters dialog box.

Analog Output Parameters
Analog output parameters include the analog output signal type, analog output data type, analog output minimum and
maximum values, analog output data, and analog output operating status. This section describes these parameters in detail.
Analog Output Signal Type
A total of three analog output signal types are available, depending on the analog I/O or analog output module. Select an
analog output signal type for each analog output channel. When a channel is not used, select the default value or Not used
for the channel.
Analog Output Data Type
A total of two analog output data types are available, depending on the analog I/O or analog output module. Select an analog output data type for each analog output channel.
Analog Output Minimum/Maximum Values
For analog output values, when Optional range is selected for the Data Type, designate the analog output data minimum
and maximum values which can be –32,768 through 32,767.
Analog Output Data
The analog output data is converted into an analog output signal within the range specified by the analog output data type
and applicable parameters. The analog output data register number is shown under Data in the Configure Parameters dialog box.
END Refresh Type
The analog output data stored in a data register, such as D772, is converted into an analog output signal of voltage output
(0 to 10V DC) or current output (4 to 20 mA) as designated by the value stored in the data register allocated to analog output signal type, such as D774.
While the CPU module is running, the analog output data stored in the allocated data register is updated at the END processing of every scan or 10 ms, whichever is longer. While the CPU module is stopped, the analog output data remains at 0
or the designated analog output data minimum value, so the generated analog output signal remains at the minimum value
of 0V DC or 4 mA DC.
Ladder Refresh Type
While the CPU module is running, the analog output data stored in the allocated data register is updated when the RUNA
instruction contained in the ANST macro is executed. While the CPU module is stopped, the analog output data is not
updated. But the analog output signal can be changed by using the STPA instruction. For details, see page 4-21.
Analog Output Operating Status
The operating status of each analog output channel is stored to a data register allocated to analog output operating status.
While the analog output is operating normally, the data register stores 0. The analog output operating status data register
number is shown under Status in the Configure Parameters dialog box.
END Refresh Type
The operating status of each analog output is stored to a data register, such as D773. While the analog output is operating
normally, the data register stores 0. The analog output operating status data is updated whether the CPU module is running
or stopped. The update occurs at the END processing of every scan or 10 ms, whichever is longer.

As shown in the ladder diagram below, when initialize pulse special internal relay M8120 is used for the ANST macro in
parallel with another instruction, load M8120 again for the other instruction.

M8120 is the initialize pulse special internal relay.
When the CPU starts to run, ANST stores parameters to
data registers to configure analog I/O modules and Q30
is turned on.
When I0 is turned on, analog input data is moved from
D676 to D1000.
The temperature is compared with the alarm temperature of 100°C.
When the temperature is higher than 100°C, Q30 is
turned off.
When the temperature is not higher than 100°C, Q30 is
turned on.
Analog input data of –500 to +1500 is converted to 0 to
2000.
Analog input data of 0 to 2000 is converted to 0 to
4000.
Analog input data of 0 to 4000 is moved to D772 (analog output data) of the analog output module.

Changing Analog Output While CPU is Stopped
When using the FC4A-K2C1 analog output module, the analog output value can be changed while the CPU module is
stopped. To change the analog output value, store a required output value to the memory addresses allocated to the analog
output data.
Example: Memory Allocation of Ladder Refresh Type Analog Output Module FC4A-K2C1
STPA instruction when FC4A-K2C1 is mounted on slot 4

Precautions for Programming ANST Macro
When using the ANST macro, do not make a branch from the ladder line of the ANST macro.
Delete the branch from the ANST macro, and start another line by inserting a LOD instruction.
