RTU request over RS-232 to Ethernet converter


  • Hello,
    I have a scenario where a RTU RS-232 modbus device is connected to PC using a RS-232 to Ethernet converter.
    I can only use TCP to comunicate to the device, via the RS-Ethernet converter.
    Which kind of ModbusMaster shall I use ?
    Is there any way to transparently issue RTU requestes over the TCP connection ?

    Thanks is advance.


  • I reply to myself.

    Simply set encapsulated to true when creating the IpParameters.

    
    IpParameters ip = new IpParameters();
    ip.setHost("192.168.15.30");
    ip.setEncapsulated(true);
    ip.setPort(4001);
    
    ModbusFactory factory = new ModbusFactory();
    ModbusMaster master = factory.createTcpMaster(ip, true);
