Module Error Collection Function

The errors that occurred in the flexible high-speed I/O control module are collected in the CPU module.
To hold errors even after the power is turned off or the CPU module is reset, save the errors in the memory that can hold data
during power failure in the CPU module.
Error history (CPU module including built-in I/O and built-in
CC-Link) and error log (intelligent function module) are
displayed on one screen.
Errors that occurred in the entire system can be
monitored in reverse chronological order.
