Hey guys,
Been having an issue with a AB CPU 1756 L62S (red safety) randomly losing the program while in run.
Things i have tried or replaced.
Replace backplane
Added more chasis grounds
Replace 24V source to backplane Ps
Replace L62S and slave
Replace all local I/O
Issue happens randomly machine could run for months without happening or sometimes will happen 2 days in a row
Faults present when downloading the program again
Type 14 safety task fault
Code 9 - a non recoverable fault has occurred in Safety Partner
If anyone can help will be highly appreciated.
Thanks in advance.
