Hello, 1. It will be better if you send you logic here. Or even make screen shots of FC1 and OB1. 2. I guess that you may called FC1 in OB1 and then you have assigned inputs and outputs to the FC1 out of the data area of the CPU312. Please note that CPU312 works with memory areas between MB0 and MB255. 3. Or may be you have assigned bits in a DB without defining it in the software. Please check and tell us. Hope this helps, |

Hello alibb have a look into the Diganostic Buffer which will tell you what the problem is. You can find it in the PLC menu under "Diagnostic/Setting" --> "Module information" (or use "CTRL+D" as a shortcut). I hope this helps P.S: Could it be that"forgot" todownload FC1? |
Cheers |
