C.3
PLC non-fatal error SM flags
Overview
Non-fatal errors are those that may degrade some aspect of PLC performance, but do not
render the PLC incapable of executing the user program and updating I/O. To help you in
debugging your program, information associated with error conditions is stored in Special
Memory (SM) locations (Page 799), which can be accessed by the user program. For
example, if you do not want to continue in RUN mode with certain non-fatal error conditions,
you can have the user program force a transition to STOP mode when the undesirable
condition occurs.
The following table lists and describes the Special Memory non-fatal error information.
