Introduction
About the Analog I/O Modules
END Refresh Type and Ladder Refresh Type
This chapter describes general information and specifications of the FC4A series MicroSmart 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.

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 con-
trolling 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 macro is executed, so analog I/O parame-
ters can be changed while the CPU is running.

At the end processing
When M8025 (maintain outputs while CPU
stopped) is on, output data is refreshed.
When off, output is turned off.
