Figure 20 NAM State Table
The state must be NAM_ATTACHED to send messages and scan I/O.
All other states are intermediate states as the MBCN becomes attached to
the network. An application should check the NAM state before it starts
accessing data.
Keeper State
On a ControlNet network, a keeper is a node that stores and distributes
the network parameters, as well as storing the network configuration
database.
Refer to the ControlNet specification, Part 10, Table 10-246 for detailed
information on Keeper object operating states.
An application can use the KeeperState register (9476) to determine the
current keeper operating state. The following table lists the possible
values.
