Hi all,
Just got a call from one of my clients, there has been a ton of lightning around me they got hit. Turns out the SLC 5/05 was faulted. Now in previous years, said client has had an issue where if you try to download a program to the PLC it can fault, you guys helped me figure that out (pull off battery, short terminals to erase memory, then reflash). Trying that this time, however, sounds like it's not working. I can't remote into the system since their internet is down, but I'm going to have the lead operator do the memory clearing procedure one more time and then take a look myself. If the fault is still not cleared, my guess is that either the power supply, CPU module, or both have been damaged. I don't want the client having to buy replacement parts unnecessarily since they're not cheap, so I was wondering if anyone here has some suggestions for how to troubleshoot this system and be able to confidently tell the client what's wrong and how to best fix it, instead of just throwing parts at it until it works again.
Any suggestions would be highly appreciated, thanks guys!
