7.7.2 Common practice commands
14 Read sensor information on
primary value
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 value
• Byte 4-7: Upper sensor limit
• Byte 8-11: Lower sensor limit
• Byte 12-15: Minimum distance between limits
Depending on the assignment of current output 1, the
sensor information from sensor 1 or sensor 2 is returned.
15 Read output information of the
primary value
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 value
• 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 = E+H
16 Read the device production
number
Access type = Read none • Byte 0-2: Production number
You can write the production number using command
19.
17 Write user message
Access type = Write You can save any 32-character long text in the device
with this parameter:
Byte 0-23: Desired user message • Byte 0-23: Current user message
18 Write tag, tag description and date
Access type = Write You can save an 8-character tag, a 16-character tag
description and a date with this parameter:
• Byte 0-5: Tag name
• Byte 6-17: TAG description
• Byte 18-20: Date
If the tag name is changed, the user tag that can be set at
the device is also changed.
• Byte 0-5: Tag name
• Byte 6-17: TAG description
• Byte 18-20: Date
19 Write the device production
number
Access type = Write You can save a production number in the range of 0 ...
1677715 with this parameter. • Byte 0-2: Production number
Command No.

34 Write attenuation constant for the
primary value
Access type = Write Byte 0-3: Attenuation constant of the primary value in
seconds Byte 0-3: Attenuation constant in seconds
35 Write measuring range of the
primary value
Access type = Write Write the desired measuring range:
• Byte 0: HART unit ID for the primary value
• Byte 1-4: End of measuring range, value for 20 mA
• Byte 5-8: Start of measuring range, value for 4 mA
• Byte 0: HART unit ID for the set measuring range of
the primary value
• Byte 1-4: End of measuring range, value for 20 mA
• Byte 5-8: Start of measuring range, value for 4 mA
