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.
