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 ID of the primary process
variable
– Bytes 5-8: primary process variable
– Byte 9: HART unit ID of the second process
variable
– Bytes 10-13: second process variable
– Byte 14: HART unit ID of the third process
variable
– Bytes 15-18: third process variable
– Byte 19: HART unit ID of the fourth process
variable
– Bytes 20-23: fourth process variable
Factory setting:
• Primary process variable = Volume flow
• Second 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 shortform 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
set to 4 mA.
Byte 0: active address
11
Read the unique device
identifier using the TAG
Access type = Read
Bytes 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, 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
12
Read user message
Access type = Read
none
Bytes 0-24: user message
!
Note!
You can write the user message using
command 17.
Command No.
