Proline Prowirl 72 5 Operation
E Hauser 35
Common practice commands
34 Write attenuation constant for
primary process variable
Access = Write
Byte 0-3: attenuation constant of the primary
process variable in seconds
Factory setting:
Primary process variable = flow
Displays the current attenuation constant in the device:
Byte 0-3: attenuation constant in seconds
35 Write measuring range of the
primary process variable
Access = Write
Write the desired measuring range:
– Byte 0: HART unit ID for the primary process
variable
– Byte 1-4: end of measuring range, value for
20 mA
– Byte 5-8: start of measuring range, value for
4 mA
Factory setting:
Primary process variable = volume flow
!
Note!
If the HART unit ID does not suit the process
variable, the device will continue with the last
valid unit.
The measuring range currently set is shown as the response:
– Byte 0:
HART unit ID for the set measuring range of the primary process
variable
– Byte 1-4:
end of measuring range, value for 20 mA
– Byte 5-8:
start of measuring range, value for 4 mA (is always at “0”)
!
Note!
Manufacturer-specific units are represented using the HART unit
ID “240”.
38 Device status reset
“configuration changed”
Access = Write
None None
40 Simulate output current of the
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:
Byte 0-3: output current in mA
Factory setting:
Primary process variable = flow
The current output current of the primary process variable is
displayed as a response:
Byte 0-3: output current in mA
42 Perform device reset
Access = Write
None None
44 Write unit of the primary
process variable
Access = Write
Specify the unit of the primary process variable.
Only units which are suitable for the process
variable are accepted by the device:
Byte 0: HART unit ID
Factory setting:
Primary process variable = flow
!
Note!
• If the written HART unit ID does not suit the
process variable, the device will continue
with the last valid unit.
• If you change the unit of the primary process
variable, this has an impact on the 4...20 mA
output.
The current unit code of the primary process variable is displayed as
a response:
Byte 0: HART unit ID
!
Note!
Manufacturer-specific units are represented using the HART unit
ID “240”.
