[PLC Program stops running]

Having discovered that the PLC has stopped because of an illegal operation, is it possible to discover which line caused the error, in a similar fashion to "list apc" for cooordinate systems, or otherwise?

[Sys->Time in a C Background Program]

[PowerNC?]

What is PowerNC please? We are new to PPMAC, I am hoping it is an RS274 implementation. Richard
