Checking Module Operation
You must check to see that the module is configured in the
memory of the PLC. This is important because the module will
appear to be functioning regardless of whether it is communi
cating with the PLC. To view the PLC I/O configuration chart
listing all slots on the base and the inputs or outputs associat
ed with each slot, refer to your Programming Manual. An ex
ample chart is shown in the following figure.
I/O MODULE DEFINITION FOR CHANNEL . . . 1 BASE……….0

SLOT ADDRESS NUMBER OF BIT AND WORD I/O SPECIAL
X Y WX WY FUNCTION
01 ……… 0001 ……..1 6 ….. 00 ……. 00 …… 00…………….NO
02 ……… 0000 ………00 …… 00 ……. 00 …… 00…………….NO

I/O Configuration Chart
In this example, the 16-point discrete input module is inserted
in slot 1 in I/O base 0. Data appears as 16 “X” locations starting
at “X1”. For your particular module, look in the chart for the
number corresponding to the slot occupied by the module. If bit
locations appear on this line, then the module is registered in
the PLC memory and the module is ready for operation.
If the line is blank or erroneous, re-check the module to ensure
that it is firmly seated in the slots. Generate the PLC I/O config
uration chart again. If the line is still incorrect, contact your local
distributor or CTI at 1-800-537-8398 for further assistance.
