Error History Function

This function monitors the QD73A1's error history stored in the buffer memory.
The error history of past 16 records can be monitored. Once 16 records are stored, the next record overwrites the
oldest record. Therefore, the latest 16 errors are stored at all times.
To check the error history, the QD73A1 needs to be registered in the intelligent function module monitor window. For
how to register the module in the intelligent function module monitor window and to display the details of the history,
refer to the following.
