Response data
(numeric data in decimal form)
Universal Commands
0 Read unique device identifier
Access type = Read
none The device identifier provides information on
the device and manufacturer; it cannot be
altered.
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, 69 = Promag 10
– Byte 3: number of preambles
– Byte 4: universal commands rev. no.
– 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
1 Read primary process
variable
Access type = Read
none – Byte 0: HART unit ID of the primary process
variable
– Bytes 1-4: primary process variable
Factory setting:
Primary process variable = Volume flow
! Note!
Manufacturer-specific units are represented
using the HART unit ID “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
– Bytes 4-7: percentage of the set measuring
range
Factory setting:
Primary process variable = Volume flow
