CPU Error Log

The system stores CPU error messages in the memory card whenever the quantity of the error messages
reached to 20. You can also use special flag SM36 and special device SR36 to read the CPU error messages
and state change logs. If there is error logs recorded in the memory card, the memory card keeps storing the
error logs. You can change the file path to store other error logs or change the file name to store other error
logs.
