3-5-2 Unit Number Settings
The Special I/O Unit Area and Special I/O Unit DM Area word addresses that
each Analog Input Unit occupies are set by the unit number switch on the front
panel of the Unit.
Note 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 generated (A40113
will turn ON) and the PLC will not operate.
3-5-3 Special I/O Unit Restart Bits
To restart the Unit operations after changing the contents of the data memory
or correcting an error, turn ON the power to the PLC again or turn the Special
I/O Unit Restart Bit ON and then OFF again.
Note If the error is not corrected by restarting the Unit or turning the Special I/O
Unit Restart Bit ON and then OFF again, replace the Analog Input Unit.
