I have a SLC5/03 with 6 I/O cards and a communication card. I get a math overflow fault every time I:1.3 or I:3.12 is turned on then off. This has not happended in the past. I can force the inputs on or jump them out and get the error. I changed both input cards with known good cards. Any ideas on where to look for that problem. The program is about 400 rungs long with no comments and uses alot of MVM and Copy to write the inputs and outputs. No direct reference is made to the inputs or outputs. My thought is it is in the processor or backplane... That's the only parts we didn't switch out.
