*1 Those are values when the second error (control mode change error) occurs at 13:30:50, September 1st, 2012.
*2 The clock information of the error that occurred is based on the clock information acquired from the CPU module of the
master station. When an error has occurred before the clock information is acquired from the CPU module, the error time
is not recorded.
Error history 2 to Error history 15 (address: A10H to AEFH) are stored in the same format as that of Error history
1 (address: A00H to A0FH).
For the error code, refer to the following.
