Operation
Promag 50

Hauser
The following table contains all the common practice commands supported by the
device.
16
Read the device production
number
Access type = read
none
Bytes 0-2: Production number
17
Write user message
Access = write
You can save any 32-character long text in the device
under this parameter:
Bytes 0-23: Desired user message
Displays the current user message in the device:
Bytes 0-23: Current user message in the device
18
Write TAG, descriptor and date
Access = write
With this parameter, you can store an 8 character
TAG, a 16 character descriptor and a date:
– Bytes 0-5: TAG
– Bytes 6-17: descriptor
– Bytes 18-20: Date
Displays the current information in the device:
– Bytes 0-5: TAG
– Bytes 6-17: descriptor
– Bytes 18-20: Date
19
Write the device production
number
Access = write
Bytes 0-2: Production number
Bytes 0-2: Production number

Common practice commands
34
Write damping value for primary
process variable
Access = write
Bytes 0-3: Damping value of the primary process
variable "volume flow" in seconds
Factory setting:
Primary process variable = Current output damping
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!
• The start of the measuring range (4 mA) must
correspond to the zero flow.
• 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".
• You can change the assignment of device variables to
process variables using Command 51.
38
Device status reset (configuration
changed)
Access = write
none
none
!
Note!
It is also possible to execute this HART command when write
protection is activated (= ON)!
40
Simulate input 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
