Thanks everyone you have ALL been great help and I really appreciate it .. I’ll have a power supply this evening and a backplane Thursday

Ok thank you I know the plc had them so I wants sure I hate to keep beating this dead horse but here’s what I’ve found out … the program seems to be fine BUT after I install about 4 input cards it always resorts back to slot one isn’t empty even tho it is … it’s fine until I got over 4 cards … after 4 cards it doesn’t matter what position they are in or if I mix and match cards … so I don’t think it’s a card because I can do 4 different cards same result … my question is does this seem like a power supply issue or backplane? … I think I have one of each coming just wanna make sure I’m on the right path

Also does anyone know where the test points are for the psu?

Let me try it now

Is there a way to bypass it searching for the card in slot 1? Or force run with the error of a card was in the slot when it’s really not?

So I’ve got this far … I pointed my program at slot 7 … transferred all the inputs .. now it faults with error and says slot 1 is detected as having an io card but the user program doesn’t require it … however there is no card at all in slot 1 but it thinks there is

I have another identical … I wouldn’t think both went bad at the same time … I slid it in slot one same issue

Yes

So I just stumbled on this … keep in mind this has ran for years so maybe my psu low voltage is the issue?

Ok I do believe I have found a saved copy of the program (latest) version it does exactly the same “rack data error check slot 1) … is it possible I could change everything that’s pointed at slot 1 to an empty slot? .. my psu only about 22v and not 24 is that enough to cause the issue? do I need to go line by line to delete all the io as Chris suggested? Or is there an easy way to do this? is a 5/03 rack and power supply the same? If so I’ll go ahead and eBay one and get it headed this way just in case … I have no spare parts for slc only plc sorry it’s been a really long time for me

Ok working on it now thank You all so much

It’s been a while since I used an slc but I right click on “controller properties” I believe it is and looked at what card was assigned to which position and it appears to be correct … it’s in a very very clean cabinet but that doesn’t mean a chassis or card didn’t go bad it’s in a climate controlled building… I’ve had plenty go bad on a plc5 in a mining environment … is there a way to trouble shoot the card vs chassis? …. I feel like there’s just something I’m missing since it loaded from eeprom when that battery went dead however it might have been multiple things failed at once

So the bad news is I inheairted this plant … I do not have the original file .. I can download the program from the SLC but it doesn’t include any details … this plant was on and working and just shut down if that means anything?

Also I tried another input card and seems to do the same thing … I believe the battery went dead and loaded from eeprom but ice loaded from eeprom before with no issues

16 Channel input card … slot 0 is the slc5
