Using the ControlNet-to-FOUNDATION Fieldbus H1 Linking Device

Because existing programs may be using a configuration, the deletion of a
linkage from a Fieldbus network does not result in a renumbering of
ControlNet objects or a reordering of the assembly object offsets. If the
Fieldbus device is no longer present, Fieldbus and ControlNet status
indicates an error condition, and the object and assembly offset resources
continue to be in use. In order to remove existing objects from a
configuration, you must remove the existing configuration. To accomplish
this, select Download Configuration in the NI-FBUS Configurator, enable
the Clear Devices checkbox in the dialog box that appears, and download a
new configuration.

Trends and Alarms

The linking device can receive trends and alarms from connected Fieldbus
devices.

Use NI-FBUS configurator to connect trends and alarms to the linking
device. Within the function block application, drag the linking device icon
from the browse window. Connect trends and alarms as necessary from
Fieldbus devices to the trends or alarms inputs. Refer to the NI-FBUS
Configurator User Manual, publication 1788-6.5.2, for additional
information.
