34 E Hauser
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 (= 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
– 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
Primary process variable = flow
!
Note!
Manufacturer-specific units are represented using the HART unit
ID “240”.
