Link-Master Capable
A Link-Master-Capable device can take over control of a link.
When FIM first encounters a new uncommissioned device, it
checks to see if it is configured as a Link-Master capable device
and re-configures it as a Basic device. (When the device is
commissioned, it can be changed back to Link-Master capable,
since it will be loaded with the correct backup link schedule.)
Binding of Fieldbus Devices
to the Experion database
The three most important identification parameters for a
fieldbus device are its:
Device_ID,
PD_Tag, and
Link Address.
The Device_ID is required by Fieldbus Foundation
specifications to be device-unique and unchangeable. But, if
either the Physical Device Tag (PD_Tag) or the Link Address is
changed while the device is off the network, the device is de-
commissioned and will have to be re-commissioned when it is
returned to the link.
If a device is removed from the link and another device is
placed on the link at the same address (second device will have
different Device_ID and possibly different PD_Tag), the original
device will appear de-commissioned upon return to the link.
To recover, the (now uncommissioned) device must be re-
commissioned or matched again to its device object and then
re-loaded.
