Sumon Sadhukhan Posts: 1 Rating: (0)	Hi All, I am trying to establish a connection betweenCPU313C-2 DP with CP 343-1 Lean with ModScan 32. As per manual I configured the PLC as SERVER. But no communication happening and ModScan message shows "MODBUS MESSAGE TIMEOUT". In ONLINE mode the BUSY bit remains false everytime and in Netpro the connection always remains passive not established. I attached the programme backup. Please suggest what to do?
