(3) SFC error history device
The error information for up to eight past errors after turning ON the CPU power
supply is stored as a history. The error information of #8056 to #8063 contains
newest error.
The error during SFC control, and conventional errors such as minor error, major
error, servo error, servo program error, mode select error, etc., are all integrated
in the history.
When an error occurs, the "SFC error detection signal M2039" is set at the same
time.
The error information is as shown below.
