Summary:
How do I set up CitectSCADA to talk to an AB MicroLogix 1200 PLC via an AB 1761-NET-ENI Module using RSLINX and CitectSCADA's ABRSLINX driver? 

Solution:
  1. Within RSLinx, add a new driver using the Ethernet Device Driver, and specify the IP Address of the remote ENI module (in our case, we used 192.168.1.213). This creates a new AB-ETH driver (typically named AB_ETH-1, however the driver in our example is called AB_ETH-2). The driver should appear within the RSWho window as follows:

 

 

  1. For a simple network, where the Citect server and ENI module are directly connected via Ethernet, and no routing via other PLCs is required, fill in the communications forms within your Citect project in a similar manner to the following (Note that the text in Special Options within the Ports form matches the name of the driver in RSLinx pictured above):

 

Note: The address field should be: 'AB:NAME,192.168.0.1' (without the surrounding quotes). Replace only the IP address with that of your device and leave the AB:NAME, prefix as is.

  1. Add variable tags to your project using the usual AB PLC addressing conventions (eg. N7:0 for the first integer in integer file 7).
  2. Compile your project
  3. Run Computer Setup from Citect Explorer to verify your INI settings for Server setups and selected project are correct.
  4. Run Project.
