Using an Ethernet Card

Ethernet is one of the most popular methods of communicating with a number of I/O Devices at high speed. It is certainly one of the easiest to configure. You can typically connect to Ethernet capable I/O Devices using a standard Ethernet card, or integrated Ethernet port.

To set up CitectSCADA to use your computer's Ethernet card:

  1. Make sure that your Ethernet card is installed correctly and working under Windows.
  2. Make sure that the Boards configuration has TCP/IP as the Type, and the Address set to 0. The I/O Port, Interruptand Special Opt can be left blank.
  3. In the Ports form, use the Special Opt field to enter the destination IP address using the following format:
  4. -Ia -Pn -T


    a = the destination IP address in standard Internet dot format. (For example

    n = the destination Port number. Often one physical port has several virtual ports, used for different purposes. Use this option only if you want to override the default of 2222.

    T = forces the driver to use TCP (the default), rather than UDP (-U).

    (See TCP/IP driver special options reference for more information)

    Leave other fields blank. You can now define your I/O Device units.

Note: You only need to define the TCP/IP board once. You can then add several ports that use the same CitectSCADA board.
