Hi guys! I have a network communication problem. Now, i am trying to connect WinCC server and S7-300 PLC through TCP/IP. * PLC1 : (IP)10.54.110.51 / (Subnet) 255.255.254.0 / (Gateway) 10.54.110.1 * PLC2 : (IP)10.54.111.51 / (Subnet) 255.255.254.0/ (Gateway) 10.54.110.1 * WinCC Server: (IP) 10.54.105.56 / (Subnet) 255.255.255.0/ (Gateway) 10.54.105.1 I can connect to PLC1, but NOT to PLC2. ***102 port is needed to be opened when we connect WinCC(v7.4 SP1) and PLC(S7-300) through S7 Protocol . -> I tried to command "TELNET" to check whether 102 port is opened in WinCC Server to PLC2, but it didn't answer. 1) WinCC server <-> PLC1 communication is OK - Ping to PLC OK - Telnet 102 OK 2) WinCC server <-> PLC2 communication is Bad - Ping to PLC OK - Telnet 102 X I need to know right Dynamic range of port in case of Multiple connection(Two different IP Ragne of PLC). Or, any other ports missing for configuration of firewall between WinCC Server and PLC? Pleas help me !! Regards -Christina_jin- |

Hi I don´t know where is the problem, but I suggest to open Channel Diagnosis and see what kind of error do you have. maybe this can help you to find what is happening. There is too the file to log all the drivers you have it, you can find it, C:\Program Files (x86)\Siemens\WinCC\diagnose Regards |
