Once the PLC successfully initiates the Start Network Services command, the module will begin using the IP
parameters specified in the command and will enable all module network services. The MSD should display the IP
address and subnet mask (in CIDR format) specified by the PLC logic. The NS LED should be S

for troubleshooting instructions.
Entering the Module into the PLC I/O Configuration
If you want to use PLC logic to monitor and/or control the module operation, you must enter the 2572-B into the PLC
I/O configuration using your PLC programming application. The 2572-B is configured as a Special Function module with
2 WX and 6 WY words. In the following example, the 2572-B module is installed into slot 1 on I/O base 0 (local base)
and will be logged in starting at address 1.
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 CTI customer support.
NOTE:
The module must be configured in the I/O table before you can use PLC logic to start the module, monitor
the module status, or control the module operation.
Storing Network Parameters in Flash
If you have selected the AutoStart option (SW4), you will need to manually set the IP parameters to correspond to
your networking requirements.
The 2572-B IP Parameters can be set using the embedded web server. Point your browser to the main Product
Information page by entering the IP address of the 2572-B module in the browser URL field. From the list of pages on
the left hand side of the page, select the M
