Common practice commands
34
Write damping value for primary
process variable
Access = Write
Byte 0-3: damping value of the primary process
variable in seconds
Factory setting:
Primary process variable = Volume flow
Displays the current attenuation constant in the
device:
Bytes 0-3: attenuation constant in seconds
35
Write measuring range of primary
process variable
Access = Write
Write the desired measuring range:
– Byte 0: HART unit code for the primary process
variable
– Byte 1-4: end of measuring range, value for 20 mA
– Bytes 5-8: start of measuring range, value for 4 mA
Factory setting:
Primary process variable = Volume flow
!
Note!
• If the HART unit code is not the correct one for the
process variable, the device will continue with the
last valid unit.
The currently set measuring range is shown as the
response:
– Byte 0: HART unit code for the set measuring range
of the primary process variable
– Byte 1-4: end of measuring range, value for 20 mA
– Bytes 5-8: start of measuring range, value for 4 mA
!
Note!
Manufacturer-specific units are represented using the
HART unit code "240".
38
Device status reset "Configuration
changed"
Access = Write
none
!
Note!
This HART command can also be executed if the write
protection is switched on (= ON)!
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:
Byte 0-3: output current in mA
Factory setting:
Primary process variable = Volume flow
The momentary 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 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 code
Factory setting:
Primary process variable = Volume flow
!
Note!
• If the written HART unit code is not the correct one
for the process variable, the device will continue
with the last valid unit.
• A change of the unit of the primary process variable
has a direct impact on the system units.
The current unit code of the primary process variable
is displayed as a response:
Byte 0: HART unit code
!
Note!
Manufacturer-specific units are represented using the
HART unit code "240".
48
Read extended device status
Access = Read
none
The current device status is displayed in extended
form as the response:
