You can save any 32-character long text in the device
under this parameter:
–
Byte 0 23: Desired user message
With this parameter, you can store an 8 character
TAG, a 16 character TAG description and a date:
–
– Byte 0 5: TAG name
–
– Byte 6 17: TAG description
–
– Byte 18 20: Date
–
Byte 0 3: Damping value of the primary process
variable in seconds
Factory setting:
Primary process variable = Volume flow
Proline Prosonic Flow 90
Response data
(numeric data in decimal form)
–
– Byte 0 2: Sensor serial number
– Byte 3: HART unit code of the sensor limits and
measuring range of the primary process variable
–
– Byte 4 7: Upper sensor limit
–
– Byte 8 11: Lower sensor limit
–
– Byte 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".
– Byte 0: Alarm selection code
– Byte 1: Transfer function code
– Byte 2: HART unit code for the set measuring range
of the primary process variable
–
– Byte 3 6: End of measuring range, value for 20 mA
–
– Byte 7 10: Start of measuring range, value for 4 mA
–
– Byte 11 14: Attenuation constants in [s]
– Byte 15: Write protection code
– Byte 16: OEM dealer code, 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 ID "240".
