  2. Hello everyone, we have started to use a new Schneider PLC M238 and we have some problems with Modbus communication. We are reading holding registers (%MW49=400050) and writing to this modbus register. This work's OK. Now we need to write a coil. On the M340 this was done like this: %M100= modbus register 000101. How can we write a single coil to the M238? best regards

    Hi, I am going to use xCP Modbus slave driver for CP340 Now I have another problem. How to configure CP340 communication paramateres (baudrate, data bits, parity,..), because in the HW Config, where I can configure CP340 the button Parameters (Properties - CP340 RS232C...) is not enabled.

  7. Siemens S7-313C and CP340

    Hello everyone! I have just recived a CPU S7-313C with DI/DO modules, CP340 communication card and MD720-3 gprs modem. This is a water plant wich I need to put into scada iFix. I have a few experience with simatic plc but not very much with communication protocols with S7. I know this CP340 card does not support modbus protocol (driver). What protocol does this card support so I can linked to iFix scada. Is this SI7 or something else and how do I do it? Best regards

  10. Hello! How can I see if I have the same project wich is on the PLC (Micro) with Modsoft software if I go online to PLC? Please help

    The twido port 1 is set to Modbus and not to Remote link. And yes I have PIN5 and PIN7 on the MINIDIN together and connected to COM on the coverter from the start. I think Henrique is wright. Twido has a limitation in comm. packet.

    I don´t know what else to try. Please help.

    I am using Mb1 opc server from geFanuc for modbus serial communication. My communication parameters are 9600,8,1,N (RTU) and Twido has modbus address 2. I am reading registers 400001 to 400008. I am using a coverter from RS485 to RS232, because Twido has RS485 port. If I connect Modicon momentum to this OPC server it work´s OK. What am I doing wrong?
  14. Hello! I am trying to communicate with TWIDO TWDLCAA10DRF trough modbus OPC server. The server doesen´t poll the data from TWIDO. If I poll the same data with modscan, it work´s OK. Are there any additional settings to make in the Twdio so it will communicate with opc server? This standard modbus OPC server communicate´s fine with any other PLC´s. Have a nice day
  15. I think the cable is OK. The dialog table on the XBTH is configured. What do I have to configure on the Twido PLC? Do you mean with the EXCH function? Best regards
