Module Error Collection Function

Errors that occurred in the QD73A1 are collected into the CPU module.
The error information of the QD73A1 module is held in a CPU module memory as a module error history, even when
the power is turned off or the CPU module is reset.
Error history (CPU module) and error log
(intelligent function module) are displayed on
one screen.
Errors that are detected in the entire base
system can be monitored in chronological order.
