Universal / common practice HART commands

The following table contains all the universal and common practice commands sup-
ported by Prosonic Flow 90.

Response data
(numeric data in decimal form)
Device identification provides information on
the device and manufacturer and 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, 88 = Prosonic
Flow 90
– Byte 3: Number of preambles
– Byte 4: Rev. no. universal commands
– Byte 5: Rev. no. device-specific commands
– Byte 6: Software revision
– Byte 7: Hardware revision
– Byte 8: Additional device information
–
– Byte 9 11: Device identification
– Byte 0: HART unit code of the primary proc-
ess variable
–
– Byte 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".
–
– Byte 0 3: Present current of the primary
process variable in mA
–
– Byte 4 7: Percentage of the set measuring
range
Factory setting:
Primary process variable = Volume flow
