Hi everyone, I have a problem connecting Unistream and Siemens WinCC over Modbus TCP protocol. My equipment is: Unistream US5-B10-T30 WinCC Professional V15.1 Project on Unistream is example "Modbus_TCP_Slave.ulpr Two coils with address 40 and 50 Two holding registers 100 and 101 On the WinCC side, connection is defined as Modicon Modbus TCP CPU type Unity,PL7 Port 502 Server (IP address of panel) Remote slave address 1 (as in unistream) For the HMI Tags I try MW40, MW50, MW100, MW101 and meny other combinations (x4, x3, shift one bit,...). Can you point me to right direction.
