Here are some quick trouble shooting answers:
• Power light on module is off: Check that the “Cable/External” switch is
set to “Cable” and that you are using the correct cable (see “Networking
instructions for the newer AB OS/OA Blender”). The module gets power
from the PLC.
• Fault light on module is on: Check to ensure that the DCOMM light on
the PLC is on, if not you need to enable DCOMM by removing the snap
cover on the PLC and holding in the COMMS button. Reboot after
changing:
• Power light on module is on, Fault light on module is off, but Link light
on module is off: This is a problem on the Ethernet side of the module
and not the PLC side. Check your cables and hubs (or switches) to
resolve the issue. You can bypass your network by using a crossed-
cable and a laptop or computer that has Ethernet. Plug the crossed-
cable directly from the module to the computer. If the Link light comes
on then the problem is within your network.
