Set the Node Address
(ControlNet only)
Every ControlNet network requires at least one module that can store parameters
and configure the network with those parameters upon startup. The
CompactLogix controller is called a keeper because it keeps the network
configuration.
The CompactLogix controller can keep the network parameters at any legal node
address (01…99). Multiple devices on any one network can act as the network
keepers. Each device capable of being the network keeper acts to back up the
current keeper. This back-up function is automatic and requires no action on
your part.
Node address switches are set to the 99 position at shipment, as shown in the
figure.
Use these steps to set the node address.
