I have a new 1211C to play with so I decided to test its Modbus TCP instruction.
I have followed the guide below but it seems that I can't establish connection.

I don't have a hardware client so use software modbus TCP client emulators like http://www.simplymodbus.ca/TCPclient.htm
http://www.modbustools.com/modbus_poll.html
I can download my program to the PLC but I have no connection through Modbus TCP.
What could be the problem?
