Module Error Collection Function

Collects the errors and alarms that occurred in the A/D converter module, into the CPU module. By holding the module
errors in a memory that can hold data in the event of power failure, the errors can be held even after power-off or reset.
Error history (CPU module) and error log (intelligent
function module) are displayed in one screen.
Errors that occurred in the entire system (base units)
can be monitored in reverse chronological order.
