    When I'm testing connection (with command ./testISO_TCP -d -b 172.21.49.139) to PLC I get following output:

    openSocket: enter OpenSocketopenSocket: OpenSocket: socket is 3
    openSocket: setsockopt Success 1
    openSocket: Connected to host: 172.21.49.139
    openSocket: setsockopt Success 0
    send packet: : 03,00,00,16,11,E0,00,00,00,01,00,C1,02,01,00,C2,02,01,02,C0,01,09,
    timeout in ReadISOPacket.
    IF1 daveConnectPLC() step 1. got packet: :

    IF1 error in daveConnectPLC() step 1. retrying...Couldn't connect to PLC.
    Please make sure you use the -2 option with a CP243 but not with CPs 343 or 443.

    Anybody know what's wrong? My ethernet adapter is CP 443-1.

      I guess your CPU is in slot 3 in 4xx system. Default for testISO_TCP is 2, which is ok for 3xx systems. Try:
      testISO_TCP --slot=3 172.121.49.139
