This hasn't become my problem yet, but it may soon...
Ancient PLC-3 (yeah, I know) has been humming along for decades. It now has some analog values that are moving and some have frozen in place. For example a watts transducer is reading 1056 kw when it should read 0.
That's all I know at this point. I've never been online with a PLC-3. I'm wondering if maybe the block transfers for certain modules have stopped executing for some reason.
Posting here on the off chance someone has seen this before.
