Ladder Instructions for Loop Back Diagnostics Test

This rung is used to test the loopback information. Command should
equal feedback when the move is complete. The Module is shown in
slot 1 for this example.

EQU
EQUAL
I:1.2 Source A

NOTE: In the above rung, use of the EQU (equal) test means that
source A equals the command in both the MSW and LSW words;
source B in both cases, is the value reported by the loop back
diagnostic.
