CPM1A Programmable Controllers Operation Manual 1784470
Error Flags When the self-diagnosis function detects a hardware error, it will turn on the cor-
responding error flags in the SR and AR areas.
Error Code When an error is detected by the self-diagnosis function, the corresponding
error code is written to SR 25300 to SR 25307. (The error code is an 2-digit hex-
adecimal code.)
5-3-4 User-defined Errors
There are three instructions that the user can use to define his own errors or
messages. FAL(06) causes a non-fatal error, FAL(07) causes a fatal error, and
MSG(46) sends a message to the Programming Console or host computer con-
nected to the PC.
