Bill, Thank you for your response. I will try to clarify your further questions: Can you zip up the..\Siemens\WinCC\Diagnose folder and post it so I can look at it? - attached Are both servers connected to the PLCs and do they simultaneously lose the connection? - No, either, but both are doing it. How many tags are you reading from the PLCs and what cycle times are you using for the tags? - 13700 tags but mainly from S7s no more than 300 from the two 555s =, 2 s standard Do you have any information from the switch on the number of bad packets and retries for the ports the PLCs are on? - I have gone through this before and dismissed it, 0 errors, fragments and collisions on switches, the network is very solid. I can dig further if need be. AttachmentDiagnose.zip (713 Downloads) |
