8-10 Connecting CompactLogix Controllers on Ethernet
Configuration Via Ladder Logic
Rungs 2 through 8, on page 8-10, and the rungs 0 and 1 shown on
page 8-5 in this application example, make up the ladder program for
the CompactLogix controller. Details of each MSG instruction follow.
Figure 8.11 ENI #2 Configuration - RSLogix 5000 Ladder Program
In the above program, Rung 2 initiates the string of configuration
messages with input instruction ‘Reconfig_ENI’. This could be an alias
to an input connected to a pushbutton for example, for quick
configuration of the ENI/ENIW module.
In an actual user application, additional logic should be included to
handle MSG error conditions (not shown in Figure 8.11).
