Hello,
I have S7-417-4H CPU having Modbus TCP/IP communication with Schneider PLC. Modbus TCP/IP communication was working. But since S7-417-4H powered OFF and ON, from that moment communication is loss. Before power ON-OFF cycle of S7-417-4H CPU communication was ok.
I am using FB909 Block i.e. "MB_REDCL" in OB1 for Communication and same Block used in OB 100 for Initialization. In S7-417-4H CPU rack there is CP443-1 Module used for TCP/IP Communication.
For S7-417-4H CPU 0 port address is 2000 and IP is 172.16.107.0. For S7-417-4H CPU 1 port address is 2000 and IP is 172.16.107.1. Port address for Schneider CPU 0 is 502 and for CPU 1 port address is 503.
Error status code of FB909 is AOFF i.e. "Connection is not ready for communication". I have checked physically the Ethernet cable and related connection but found that all connections are ok.
Please find the attachment of screen shot of simatic manager netpro TCP/IP communication fail status.
Please help me to resolve this communication problem..
Thanks
