kodbegemod, are you using failsafe I/O? F channel drivers have an acknolegement option that can be enabled/disabled on the block. |

No, we use usual modules. I attach two screenshots.

I have exactly same problem (mentioned here: https://support.industry.siemens.com/tf/ww/en/posts/addfem-uncertain-inputs-problem/190376/?page=0&pageSize=10 ) just with different I/O module. But in my case generating @plans didn't help.... Looks like this problem is related with more than one PCS7 version |

Hi all, I faced similar issue as well. This is quite weird. I believe my hardeare config and redundancy IM module do not problem, but the mode showed 16#4xxxxxxx. This caused a bad signal generated and cause the mon block to have bad communication. My solution was 1. Download hardware again (sometimes solve the issues. But sometimes not) 2. Set the "mode" input to forcing active. Force good signal 16#8xxxxxx (i lazy to troubleshoot siemens' bugs). 100% working. (Forcing available after v8.0 or 8.1 i guess. To enable, full compulacomp needed. Go to component view, s7 program folder, chart, right click, tick support forcing) Hope it helps. |
