NOTE:
If you are using the PLC Start Option, you must log the module into the I/O configuration before PLC
logic can be used to start the module network server.
2.9. Entering the Module into the PLC I/O Configuration
To enter the module into the PLC I/O configuration, you will need to use your PLC programming
application. The 2572-A is configured as a Special Function module with 2 WX and 6 WY words. In
the example below, the 2572-A module is installed into slot 1 on I/O base 0 and will be logged in
starting at address 1. Your configuration may differ.

Figure 8. Sample I/O Configuration
After you read the I/O base, if the number of WX and WY words are the same as those shown in the
example above and Special function = YES, then the PLC can recognize the module. Change the
address as required by your application and save the result. If the line is blank or erroneous, re-check
the module to ensure that it is firmly seated in the I/O base slot. Generate the PLC I/O configuration
chart again by reading the I/O base. If the problem persists, contact your distributor or contact CTI.
NOTE:
The module must be configured in the I/O table before you can use PLC logic to start the module or
control the module operation from the PLC.
