Hello! I can't solve my problem. Some times I can't connect to my PLC 416-2 (6ES7 416-2XK04-0AB0, fw 4.0.2) with Step7 via TCP/IP. If I try to go online from any part of my program, I get message "Online: Connection could not be established. Connection partner not responding". When I repeat my attempts 10-20 times I sucsessfully go online. Also I open "Diagnostic" window only after many-many attempts... In my network there are about 10 PLCs with S7-400 CPUs, but I have trouble only with one. I try to increase "Cycle load due to communication" from 20% to 25% but this can't solve my problem. I attached diagnostic screens and buffer in zip-archive. Thanks for your help! AttachmentDiagnose.zip (272 Downloads) |
