Proline Promag 51 5 Operation
Hauser 63
14 Read sensor information on
primary process variable none – Bytes 0–2: Sensor serial number
– Byte 3: HART unit code of sensor limits and
measuring range of the primary process variable
– Bytes 4–7: Upper sensor limit
– Bytes 8–11: Lower sensor limit
– Bytes 12–15: Minimum span
!
Note!
• The data relate to the primary process variable
(= volume flow).
• Manufacturer-specific units are represented using
the HART unit code “240”.
15 Read output information of
primary process variable
Access type = read
none – Byte 0: Alarm selection ID
– Byte 1: Transfer function ID
– Byte 2: HART unit code for the set measuring range
of the primary process variable
– Bytes 3–6: upper range, value for 20 mA
– Bytes 7–10: lower range, value for 4 mA
– Bytes 11–14: Damping constant in [s]
– Byte 15: Write protection ID
– Byte 16: OEM dealer ID, 17 = E+H
Factory setting:
Primary process variable = Volume flow
!
Note!
• You can set the assignment of device variables to
process variables using Command 51.
• Manufacturer-specific units are represented using
the HART unit code “240”.
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
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
Command No.
