If I guess correctly, you did a change of SFC and download changes. But you did not do an OS compilation with SFC visualization ticked. So, to resolve the problem, do an OS compilation and download OS. The issue will be resolved. |

Dear Jaz Tai, l didn't change anything from Sfc. Today our worker come to me and said " SFC do not work". so l observed SFC in Engineering station . So l saw 2 conditional didn't okey in Sfc. So l made okey this conditional. then l started SFC from Engineering Station. İt worked. But l can't run this Sfc from Client and OS. l sent u photos.zip. 1. photo is online Sfc programme. 2. Photo is all conditional okey but Sfc didn't go to next step. 3. Photo is Valve must be open( When SEI=1) but valve didn't open. Best Regards AttachmentPhotos.zip (41 Downloads) |

Dear Yellowbeard, I see. Then I think still program issue. The SFC running from ES or Client, they are all the same. The SFC is a program that running in the PLC. When the program is stuck at somewhere, did not go through, probably that steps condition was not fulfilled during that point of time. Yes, when you execute yourself and test it in ES, it works. But you gotta ask more details on the operation, how they execute it in a real plant. is it some places is waiting for too long? is it the valve opened too early? Make more assumption in each of the steps in your SFC. May I know which blocks got the problem with the condition unable to go through? Any pulse logic in front of the block? Or flip flop? or And Gate? |
