Channel 1 Ethernet
In each MSG instruction setup screen, enter in RIx:y for the Routing
Information FIle, where x is an existing RI file number or an unused file
number, and y is an unused RI element number. Each Channel 1 Ethernet
MSG Instruction must have its own RIx:y. If the RIx:y entered in the MSG
setup screen does not yet exist, then the programming software will
automatically create it when the rung is verified.
