r.suriaga Posts: 32 Rating: (0)	Hi Everybody, I have got a SIMOTION D425, in the first DP port it has two encoders as slaves and in the second DP port it has a S7-315 PN/DP as Master. The machine works normally from monday to friday. On weekend my customer turn off the machine cutting off the power supply to SIMOTION D. When he turns ON the machine on monday, the SIMOTION stays in STOP U, and the customer must move the rotatory switch from 0 to 1 and to 0 again for that SIMOTION goes to RUN. I put a blank program in the tasks Technological Fault Task, Peripherial fault task and Execution fault task. Is this normal? What can I do to avoid that this happen? What do I need to do for that SIMOTION D goes to RUN when it is energized? Thanks for your help.

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine

I've changed the system variable of Simotion _startupData.operationMode from "LAST STATE" to "RUN", it help to avoid the change from 0 to 1 and 0 again, it worked for two times, and again the same problem. The diagnostic file from IT DIAG is attached to this reply. Regards, Erwin Attachment DIAGARCHIVE.ZIP (740 Downloads)

"Error occurred while reading a system or I/O variable" (IpoSynchronousTask) In Line 91 you have a station failure on DP2 (node1). Check you peripherie , i think you read a not available I/O Point in you program, in this case the D425 go to stop. You can define a strategy for you I/O variables in Scout or a substitution value to solve this problem. Regards Christoph

You have to define the strategy for every input you have , for example in the i/o, select the byte(s) ofyour inputs and select the appropriate strategy at startup. This is definetly one of the most sad things of siemens, hehe

P.Hyldgaard Posts: 2 Rating: (1)	I had the same problem just resently with D425 v.4.3 - solved the problem by creating a startup task just with a delay timer set for 20sec. I think it helped as the profinet system thereby had sufficient time to wake-up - so to speak! I think the problem came as the new version 4.3 has much faster boot sequence than v. 4.2
