Issue

Why do I get error 79 from SYMATE PLUS when I try to insert rungs into my running SY/MAX controller from online?

Product Line

SY/MAX

Environment

SYMATE Plus

Resolution

This is due to the program using timed interrupts. As timed interrupts could not be guaranteed to be maintained during insertion, the operation is not allowed while the controller is in RUN mode. You will either need to do the operation off-line, or you need to halt the controller.
