It can work random time and then it just freezes. I attached some screen captures from online situation. What I can do with this? Attachment Problem2.jpg (305 Downloads)

MPJR Posts: 8 Rating: (1)	Yes it is multi instance, but the FB is just called once. The cycle time of this project is 11-15ms.

MPJR Posts: 8 Rating: (1)	Yes, the timer is at STATIC are. The firmware is V3.0.2. I have contacted to local Siemens tech support and they sended our code to Germany. Answer from Germany was that there is nothing wrong with our code but not answer how to solve this. Now I generated the new timer, instead of that old and hope that that works. But there are still one weird thing. Why the timer (new) ST value isT#23D_5H_28M_16S_387MS right after download?

MPJR Posts: 8 Rating: (1)	Thanks. I haven't notice that update, cause I was waiting the V13. I will test that. I also put V13 to download and try that also.

MPJR Posts: 8 Rating: (1)	I updated TiaPortal with update 4. This is strange. Now the FBs DB (looking db directly online) shows only (ST, PT, ET) 0ms values of the timer. If I look the FB at online, we have T#5s at PT value. Also tt earlier ST did showT#23D_7H_15M_54S_604MS and now its 0ms. Any ideas? Change Siemens to Codesys?? ;-)
