ControlLogix Tag names & wire#'s
ControlLogix Tag names & wire#'s
(OP)
Need to know how others are coming up with their I/O wire#'s when using Rockwell ControlLogix PLC's. We're starting to do more of these systems and need a wire # that is easily searchable in the program and also works for as a wire label (it's hard to print more than 9 characters on most wire tags).
We tried to # wires similar to a PLC-5 (example: I00114 - input-rack-slot-bit) but that didn't work because we started to have duplicate #'s. We had I/O modules in the rack with the ControlLogix PLC and also a DeviceNet rack in another panel. We ended up with two rack 1's, two slot 1's,etc.

"Local:3:I.Data.7" would have a wire tagged as L:3:I.07
