strategy database configuration through the Control Builder. You may also have to create
a new block type for the device and/or upgrade the device's firmware. Please refer to the

Guidelines for adding fieldbus device to "live"/operating Link
CAUTION
Be sure to observe the following guidelines when adding a fieldbus device
that is Link Master capable to a "live"/operating Link to avoid possible loss of
control and view.
In Experion R300.1 or greater, you can choose to enable the safe handling
option for the CIOM-A FIM instead. See the following Using optional safe
handling for new devices section for more information.
The following guidelines are provided to avoid a rare operating circumstance where a
newly added uncommissioned fieldbus device takes over the Link Active Scheduler role
due to a CIOM-A FIM failure. Since this uncommissioned fieldbus device has not been
loaded with the proper backup link schedule, it will render the link inoperative by
disrupting the periodic publication of device data over the link.
Assign and configure the appropriate block type for the new fieldbus device to the
Link in Project.
Configure the fieldbus device function blocks into the Control Strategy in Project.
Set the address for the device in the range of 248 to 251 decimal or clear the device's
address setting, so it assumes a default address in the high range when it is added to
the Link.
Inactivate the CEE and its CMs to put the CPM in its IDLE mode while the
uncommissioned fieldbus device is commissioned and loaded with the proper link
schedule.
Add the fieldbus device to the link, use the match function through the Monitoring
tab in Control Builder to match the device with its block type, and load the device
from Project.
Load the Control Strategy to CEE from Project.
Activate the CEE and its CMs to put the CPM in its RUN mode.
