Common Practice Commands
34 Write damping value for
primary process variable
Access = write
Bytes 0-3: Damping value of the primary
process variable in seconds
Factory setting:
Primary process variable = Volume flow
Displays the current damping value in the
device:
Bytes 0-3: Damping value in seconds
35 Write measuring range of
primary process variable
Access = write
Write the desired measuring range:
– Byte 0: HART unit code of the primary
process variable
– Bytes 1-4: upper range, value for 20 mA
– Bytes 5-8: lower range, value for 4 mA
Factory setting:
Primary process variable = Volume flow
! Note!
• You can set the assignment of device varia-
bles to process variables using Command
51.
• If the HART unit code is not the correct one
for the process variable, the device will con-
tinue with the last valid unit.
The currently set measuring range is displayed
as a response:
– Byte 0: HART unit code for the set measuring
range of the primary process variable
– Bytes 1-4: upper range, value for 20 mA
– Bytes 5-8: lower range, value for 4 mA
! Note!
Manufacturer-specific units are represented
using the HART unit code “240”.
38 Device status reset (Configu-
ration changed)
Access = write
none none
40 Simulate output current of
primary process variable
Access = write
Simulation of the desired output current of the
primary process variable. An entry value of 0
exits the simulation mode:
Bytes 0-3: Output current in mA
Factory setting:
Primary process variable = Volume flow
! Note!
You can set the assignment of device variables
to process variables using Command 51.
The momentary output current of the primary
process variable is displayed as a response:
Bytes 0-3: Output current in mA
42 Perform master reset
Access = write
none none
Command No.
