4.32 Module Error History Collection Function
The errors and alarms occurred with the Q64TCN are collected into the CPU module.
The CPU module keeps the error information collected from the Q64TCN as a module error history in the memory
where data is maintained even at the time of the power failure. Therefore, the information of the errors occurred with
the Q64TCN can be kept even if the power is turned off and on or the CPU module is reset and the reset is cancelled.
