Proline Prosonic Flow 91 Operation
Endress+Hauser 33
5.3.4 Universal / common practice HART commands
The following table contains all the universal commands supported by the device.
Command No.
HART command / Access type
Command data
(numeric data in decimal form)
Response data
(numeric data in decimal form)
Universal Commands
0 Read unique device identifier
Access type = Read
none Device identification delivers information on the device
and the manufacturer. It cannot be changed.
The response consists of a 12-byte device ID:
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
1 Read primary process variable
Access type = Read
none Byte 0: HART unit code of the primary process
variable
Bytes 1-4: primary process variable
Factory setting: primary process variable = Volume flow
!
Note!
You can set or change the assignment of device
variables to process variables using Command 51.
Manufacturer-specific units are represented using
the HART unit code "240".
2 Read the primary process variable
as current in mA and percentage
of the set measuring range
Access type = Read
none Byte 0-3: current current of the primary process
variable in mA
Byte 4-7: %- value of the set measuring range
Factory setting: primary process variable = Volume flow
!
Note!
You can set or change the assignment of device
variables to process variables using Command 51.
3 Read the primary process variable
as current in mA and four (preset
using Command 51) dynamic
process variables
Access type = Read
none 24 bytes are sent as a response:
Bytes 0-3: primary process variable current in mA
Byte 4: HART unit code of the primary process
variable
Bytes 5-8: primary process variable
Byte 9: HART unit code of the secondary process
variable
Bytes 10-13: second process variable
Byte 14: HART unit code of the third process
variable
Bytes 15-18: third process variable
Byte 19: HART unit code of the fourth process
variable
Bytes 20-23: fourth process variable
Factory setting:
Primary process variable = Volume flow
Secondary process variable = Totalizer
Third process variable = Sound velocity
Fourth process variable = Flow velocity
!
Note!
Manufacturer-specific units are represented using
the HART unit code "240".
