9.11 Event History Function
The "event history function" is used to save the error information and the operation for the module as an event in the data
memory or an SD memory card of the CPU module. The saved event information can be displayed with an engineering tool
and the occurrence history can be checked in chronological order. The detail information of the error also can be checked by
referring to "Optional information" in event history.
*1 Displays a value set by the clock function of the CPU module.
