I am getting a Fault 5h (retentive data is lost) on a ML1000 PLC
I clear the fault, and it comes back.. I don't really understand what the fault is, so its hard to fix it.
In the mean-time, I cleared the proc, re-uploaded the program.. Fault is still there.
Re-wrote the Ladder from scratch, and cleared the mem, re-uploaded, Fault is gone, but I need to verify that I didn't lose anything else important.
Any ideas? Is there anything important other than the ladder logic, node, and proc name? Everything seems to be working, but this is a very important project, and I want to make sure I didn't screw anything up.
