PLCforEver Posts: 99 Rating: (3)	Today, my plc decided it does not want to respond to my Field PG. I have: Simatic Field PG Step7 V5.5 + SP2 TCP/IP -> Network card PLC: CPU 314C-2DP CP343-1 Lean 6GK7 343-10X10-0XE0 / V2.2 Result: I have no accessible nodes. I can ping the CP343-1. But on a laptop with the same software, I have accessible node: pn-io. And with the original project file I can do compare, visualisation etc... With Simatic Net Diagnostic: Access point using this parameter -> S7 online SRMD_Set (..) OK[only on the laptop] SRMD_Reset (..) OK [only on the laptop] DLL Version: 8.1.2003.4124 [laptop] 8.1.2003.4274 [Simatic Field PG] Any hints or suggestions to correct this situation?
