5 Operation Proline Promag 51
64 Hauser
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 variables to
process variables using Command 51.
• 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 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
(Configuration changed)
Access = write
none none
40 Simulate output current of
primary process variable
Access = write
Custody transfer mode:
Disabled in custody transfer mode
Simulation of the desired output current of the primary
process variable. An entry value of 0 exits the simula-
tion 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
Custody transfer mode:
Disabled in custody transfer mode
none none
44 Write unit of primary process var-
iable
Access = write
Set unit of primary process variable. Only unit which
are suitable for the process variable are transferred to
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.
• If you change the unit of the primary process varia-
ble, this has no 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 additional device status
Access = read
none The device status is displayed in extended form as the
response:
