OFF

The module has not been configured for link operation.

Note

If a CPU is powered up for the first time after being received from the factory (or for the first time after its configuration has been cleared or its battery has been removed), and there is an I/O Link Interface Module present in one of the racks of the PLC, a ªLoss of Moduleº diagnostic is generated in the PLC.

To proceed, clear the fault and download a configuration to the CPU. See chapter 3 for configuration instructions. Once the CPU has been configured, the ªLoss of Moduleº diagnostic will only occur if the module subsequently fails or is removed.

Removing the I/O Link Interface Module from the Rack

1.Remove power from the rack.

2.Squeeze the rack clips on the back of the cover to disengage the clips from the rack rail.

3.Pull the module firmly to remove it from the backplane connector.

4.Slide the board along the card guide and remove it from the rack. Avoid contact with neighboring boards and wiring.
