In the uninitialized state, a fieldbus device has neither a physical device tag nor a node
address assigned by a master configuration device. The only access to the device is
through system management, which permits identifying the device and configuring the
device with a physical device tag.
In the initialized state, a fieldbus device has a valid physical device tag, but no node
address has been assigned. The device is ready to be attached to the network at a default
system management node address. Only system management services for assigning a
node address, clearing the physical device tag, and identifying the device are available.
In the operational state, a fieldbus device has both a physical device tag and an assigned
node address. Its application layer protocols are started to allow applications to
communicate across the network. Additional network management configuration and
application configuration may be needed for the device to become fully operational.
Fieldbus device matching rules
Th
e CIOM-A FIM initiates the following matching rules depending upon whether or not
the device identification (DEV_ID) is specified, when a device is loaded from Control
Builder.
If the Device
ID is . . .
And, the Device
State Is . . .
Then, the matching rule is . . .
Specified. Uninitialized
The device ID (DEV_ID) must match. If the
desired physical device tag (PD_TAG) and
node address (ADDR) are available, FIM will
assign them to the device.
Initialized
The device ID (DEV_ID) and physical device tag
(PD_TAG) must match. If the desired address is
not in use, FIM will assign it to the device.
