Clock Data Used By Intelligent Function Module - Mitsubishi Electric MELSEC Q Series User Manual

3.8.2 Clock data used by intelligent function module

Some intelligent function modules store an error code and time (clock data read from QCPU) into the buffer memory
when an error occurs.
The CPU No.1 time data will be stored as the time for the error regardless of whether the module concerned is a
control CPU or a non-control CPU.
