Operation Proline Prosonic Flow 91
34 Endress+Hauser
6 Set HART shortform address
Access type = Write
Byte 0: desired address (0 to 15)
Factory setting: 0
!
Note!
With an address > 0 (multidrop mode), the current
output of the primary process variable is set to 4 mA.
Byte 0: active address
11 Read unique device identification
using the TAG (measuring point
designation)
Access type = Read
Bytes 0-5: TAG Device identification delivers information on the device
and the manufacturer. It cannot be changed.
The response consists of a 12-byte device ID if the
given TAG agrees with the one saved in the device:
– Byte 0: fixed value 254
– Byte 1: manufacturer ID, 17 = E+H
– Byte 2: device type ID, 98 = Prosonic Flow 91
– Byte 3: number of preambles
– Byte 4: universal commands rev. no.
– Byte 5: device-specific commands rev. no.
– Byte 6: software revision
– Byte 7: hardware revision
– Byte 8: additional device information
– Byte 9-11: device identification
12 Read user message
Access type = Read
none Bytes 0-24: user message
!
Note!
You can write the user message using Command 17.
13 Read TAG, TAG description and
date
Access type = Read
none – Bytes 0-5: TAG
–Byte 6-17: TAG description
– Bytes 18-20: date
!
Note!
You can write the TAG, TAG descriptor and date using
Command 18.
14 Read sensor information on
primary process variable
none – Bytes 0-2: sensor serial number
– Byte 3: HART unit code of the 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".
