Publication 1756-UM523F-EN-P - December 2006
Configure and Program the Controller 99
Check the Keepers
To check the keepers, perform this procedure.
On a ControlNet network, each keeper must:
• take over the keeper duties if the current keeper drops off the
network.
• use the same configuration regardless of which keeper first
comes online after a major network disturbance, such as a cable
short or system power cycle.
After you schedule your ControlNet networks:
1. Make sure the network shows all keeper capable nodes.
2. Make sure that each node is a valid keeper.
For more information, see Update a Keeper Signature on page 107.
Save the Project for Each Controller
To save the project for each controller, perform this procedure.
After your schedule your ControlNet networks, save the online project
of each controller. This lets you download a project in the future
without having to reschedule the networks.
For each controller (redundant and nonredundant) on a ControlNet
network:
1. Go online to the controller.
2. Save the project.
