Note 1. The Special I/O Unit DM Area words that are occupied by the Analog Input
Unit are set using the unit number switch on the front panel of the Unit. Re-
fer to 2-5-2 Unit Number Settings for details on the method used to set the
unit number switch.
2. If two or more Special I/O Units are assigned the same unit number, a
“UNIT No. DPL ERR” error (in the Programming Console) will be generat-
ed (A40113 will turn ON) and the PLC will not operate.
