Reference Manual
00809-0100-4021, Rev GC
Status
Device is compliant to NAMUR NE 107, ensuring consistent, reliable and standardized device
diagnosti.c information.
The new standard is designed to improve the way device status and diagnostic information is
communicated to operators and maintenance personnel in order to increase productivity and
reduce costs
If self-diagnostics detect a sensor burnout or a transmitter failure, the status of the
measurement will be updated accordingly. The status may also send the PID output to a safe
value.

Schedule entries
Links
Virtual Communications Relationships (VCR)
Backup Link Active Scheduler (LAS)
The transmitter is classified as a device link master, meaning it can function as a Link Active
Scheduler (LAS) if the current link master device fails or is removed from the segment. The host
or other configuration tool downloads the schedule for the application to the link master device.
In the absence of a primary link master, the transmitter will claim the LAS and provide
permanent control for the H1 segment.
