Status Indicators

After you have completed the above steps and the controllers are listed in the Control Network, look for these indicators next to the nodes:

Indicates the downloading node (the workstation) does not have all the information about this node.
Indicates the node is not communicating. This indicator occurs if there is a bad connection, if the controller is not powered up, or if the controller is decommissioned. It also occurs for a few seconds after a controller is commissioned.
Indicates the node is communicating but has an integrity problem. Integrity problems can occur if there is a mismatch between the I/O configuration and the installed I/O or if the node is configured for network redundancy but does not have the necessary connections to support it.
Indicates that the node does not have a configuration. This can occur if the node has never been downloaded. For controllers, this can occur if there is a power failure and cold restart was not enabled for the node.
Note

If a node shows a status indicator, check for hardware faults shown in the Troubleshooting Guide before changing your configuration.

You can automate the comparison between the physical I/O and the configured I/O with the Auto-sense I/O cards command. To use the command, click on the I/O for the node, click the right mouse button, and then select Auto-sense I/O Cards. The Auto-sense Cards dialog lists the card sensed in the controller and the card listed in the database for each slot.

For example, if you add a card to the controller, the dialog displays:

Click OK to add the configuration to the database. (Clicking OK does not affect existing cards.) Click Cancel to decommission the controller and close the dialog.
