Hello Siroosh; Forcing I/Os is a debugging function, and there are limitations on S7-400H CPUs on debugging functions while operating: you cannot run and debug at the same time. See this document on the subject: https://support.industry.siemens.com/cs/ww/en/view/88867645 Hooe this helps, |

Hi All, Add on - > CFC is a tool for PCS 7 My way of doing forcing is 1. CFC , Enable support forcing You MUST enable support forcing in order to use forcing feature in CFC. To enable , go to Component View -> Under S7 Program -> Chart Folder -> Right Click Chart Folder -> Properties -> Look for Support Forcing and Enable it. Perform a chart compilation after that. Done~ 2. SIMIT - link program to Simit, simulate hardware address via SIMIT. Hope this is helpful. |

Hi Soroosh, 1. There is no Forced LED in CPU410. You may check the Forced input in Cross reference of CFC editor. When forced IO activated, you will always get reminded when you open CFC and close CFC chart. 2. For SIMIT, we bought SIMIT VC under company for program device level testing and factory acceptance test purpose. Of course, we always suggest customer to invest on SIMIT, but with two options: Option 1 - low cost: use it only device level testing - Can be achieved within 10k to 100k usd depending on licenses size. Control engineer (Owner) can use it to get familiar on the project without affecting plant operation. Integrator can use it for testing purpose and fix bug. Option 2 - high cost: develop operator training simulator: This is expensive. It consists of PLC-OS-Simit integration and Process Modeling engineering. The most expensive part is modeling. Hope this is helpful for you. |
