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 cur-
rent output of the primary process variable is
set to 4 mA.
Byte 0: active address
11 Read unique device identifi-
cation using the TAG (meas-
uring 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, 66 = Promag 53
– 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.
14 Read sensor information on
primary process variable
none – Bytes 0-2: Sensor serial number
– Byte 3: HART unit code of sensor limits and
measuring range of the primary process
variable
– Bytes 4-7: Upper sensor limit
– Bytes 8-11: Lower sensor limit
– Bytes 12-15: Minimum span
! Note!
• The data relates to the primary process
variable (= volume flow).
• Manufacturer-specific units are represented
using the HART unit code “240”.
