5 Operation Proline Promag 51
62 Hauser
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 second 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
• Second process variable = Totalizer 1
• Third process variable = not assigned
• Fourth process variable = not assigned
!
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”.
6 Set HART shortform address
Access type = write
Byte 0: desired address (0...15)
Factory setting:
0
!
Note!
With an address >0 (multidrop mode), the current out-
put 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, 67 = Promag 51
– 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
– Bytes 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, descriptor and date
Access type = read
none – Bytes 0–5: TAG
– Bytes 6–17: descriptor
– Bytes 18–20: Date
!
Note!
You can write the TAG, descriptor and date using
Command 18.
Command No.
