I am doing my first Control-Logix system. So far I am OK with it. What I typically would do with PLC-5 and SLC-500 systems is identify my wires by the plc address assigned to it. I am just curious, since the traditional I:00/00 or O:01/00 addressing does not really apply to the control logix PLC what are others doing for wire identification? A tag such as Local:2:I.DATA.0 seems a bit long for a wire ID.
