Analog I/O Modules - IDEC FC4A-C10R2 User Manual

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.

Data Register Allocation
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 con-
trolling analog I/O operation. These data registers are updated at every 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 macro is executed, so
analog I/O parameters 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.
