Proline Prowirl 73 Operation
Endress+Hauser 43
11 Read unique device identification
using the TAG (measuring point
designation)
Access type = Read
Byte 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 = Endress+Hauser
– Byte 2: device type ID, 56 = Prowirl 73
– Byte 3: number of preambles
– Byte 4: rev. no. universal commands
– Byte 5: rev. no. device-spec. 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 Byte 0-24: user message
!
Note!
You can write the user message using command 17.
13 Read TAG, TAG description and
date
Access type = Read
None – Byte 0-5: TAG
– Byte 6-17: TAG description
– Byte 18-20: date
!
Note!
You can write the TAG, descriptor and date using
command 18.
14 Read sensor information on the
primary process variable
Access type = Read
None – Byte 0-2: serial number of the sensor
– Byte 3: HART unit ID of the sensor limits and
measuring range of the primary process variable
– Byte 4-7: upper sensor limit
– Byte 8-11: lower sensor limit
– Byte 12-15: minimum span
!
Note!
• The data relate to the primary process variable
(= volume flow).
• Manufacturer-specific units are represented using the
HART unit ID "240".
15 Read output information of the
primary process variable
Access type = Read
None – Byte 0: Alarm selection ID
– Byte 1: ID for transfer function
– Byte 2: HART unit ID for the set measuring range of
the primary process variable (volume flow)
– Byte 3-6: end of measuring range, value for 20 mA
– Byte 7-10: start of measuring range, value for 4 mA
– Byte 11-14: attenuation constant in [s]
– Byte 15: ID for write protection
– Byte 16: ID for OEM dealer, 17 = Endress+Hauser
!
Note!
Manufacturer-specific units are represented using the
HART unit ID "240".
16 Read the device production number
Access type = Read
None Byte 0-2: production number
17 Write user message
Access = Write
You can save any 32-character text in the device with
this parameter.
Byte 0-23: desired user message
Displays the current user message in the device:
Byte 0-23: current user message in the device
18 Write TAG, TAG description and
date
Access = Write
You can save an 8-character TAG, a 16-character TAG
description and a date with this parameter:
–Byte 0-5: TAG
– Byte 6-17: TAG description
– Byte 18-20: date
Displays the current information in the device:
– Byte 0-5: TAG
– Byte 6-17: TAG description
– Byte 18-20: date
