Proline Prowirl 72 5 Operation
E Hauser 33
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:
– Byte 0-3: current of the primary process variable in mA
– Byte 4: HART unit ID of the primary process variable
– Byte 5-8: primary process variable
– Byte 9: HART unit ID of the secondary process variable
– Byte 10-13: secondary process variable
– Byte 14: HART unit ID of the third process variable
– Byte 15-18: third process variable
– Byte 19: HART unit ID of the fourth process variable
– Byte 20-23: fourth process variable
Factory setting:
• Primary process variable = flow
• Secondary process variable = totalizer
• Third process variable = not assigned
• Fourth process variable = not assigned
!
Note!
Manufacturer-specific units are represented using the HART unit
ID “240”.
6 Set HART short-form address
Access type = Write
Byte 0: desired address (0...15)
Factory setting:
0
!
Note!
With an address >0 (multidrop mode), the
current output of the primary process variable is
fixed to 4 mA.
Byte 0: active address
11 Read the unique device
identifier using the TAG
Access type = Read
Byte 0-5: TAG The device identifier provides information on the device and
manufacturer; it cannot be altered.
The response consists of a 12-byte device ID if the given TAG
matches the one saved in the device:
– Byte 0: fixed value 254
– Byte 1: manufacturer ID, 17 = E+H
– Byte 2: device type ID, 56 = Prowirl 72
– Byte 3: number of preambles
– Byte 4: rev. no. universal commands
– Byte 5: rev. no. device-spec. Commands
– 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 Byte 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 – Byte 0-5: TAG
– Byte 6-17: TAG description
– Byte 18-20: date
!
Note!
You can write the TAG, TAG description and date using command
18.
Command no.
