Endress+Hauser PROline promag 53 - 5.3 Brief Operating Manual to the Function Matrix

PROline Promag 53 5Operation
Endress+Hauser 71
1 Read primary process
variable
Access type = read
none – Byte 0: HART unit code of the primary proc-
ess variable
– Bytes 1-4: Primary process variable
Factory setting:
Primary process variable = Volume flow
! Note!
• You can set the assignment of device varia-
bles to process variables using Command
51.
• Manufacturer-specific units are represented
using the HART unit code “240”.
2 Read the primary process
variable as current in mA and
percentage of the set meas-
uring range
Access type = read
none – Bytes 0-3: actual current of the primary
process variable in mA
– Bytes 4-7: Percentage of the set measuring
range
Factory setting:
Primary process variable = Volume flow
! Note!
You can set the assignment of device variables
to process variables using Command 51.
3 Read the primary process
variable as current in mA and
four (preset using Command
51) dynamic process varia-
bles
Access type = read
none 24 bytes are sent as a response:
– Bytes 0-3: primary process variable current
in mA
– Byte 4: HART unit code of the primary proc-
ess variable
– Bytes 5-8: Primary process variable
– Byte 9: HART unit code of the second
process variable
– Bytes 10-13: Second process variable
– Byte 14: HART unit code of the third process
variable
– Bytes 15-18: Third process variable
– Byte 19: HART unit code of the fourth
process variable
– Bytes 20-23: Fourth process variable
Factory setting:
• Primary process variable = Volume flow
• Second process variable = Totalizer 1
• Third process variable = Mass flow
• Fourth process variable = OFF (not
assigned)
! Note!
• You can set the assignment of device varia-
bles to process variables using Command
51.
• Manufacturer-specific units are represented
using the HART unit code “240”.
