Hi everyone, had an odd occurence happen and wondering if its ever happened to anyone else in their field. Programming a GE RX3I with Quickpanel+. There is a stop button on the HMI tied to a momentary memory bit %M419. This stop button triggers multiple rung breaks and system stops throughout the program. It has been working fine for weeks. I recently added a new output to an area of the program and downloaded it touching no other pre-existing areas and suddenly when I press the stop button, it works in a few areas of the code and just refuses to read in other rungs. I can literally press the button and watch and certain rungs show the %M419 momentary input activate and the others just do not see it.
If I program a bypass in another area or overwrite that stop area, things read just fine, put it back...it does not work. I'm starting to wonder if memory corruption is a real situation here or not. Especially considering I did not change any of the original calls or stop functions...just downloaded a new edit elsewhere for myself and suddenly some rungs do not see the button activation (or pressing of it), and others do. Anyone ever witnessed anything like it?
I would hate to have to rewrite due to corruption...but starting to think this may be the case. Perhaps wiping the CPU memory entirely and a fresh download is possibly worthwhile.
