5 Operation PROline Promass 80
36 Endress+Hauser
Other operating programs
• Operating program “AMS” (Fisher Rosemount)
• Operating program “SIMATIC PDM” (Siemens)
!
Note:
The HART protocol requires the “4…20 mA setting (individual options see device
function) in the CURRENT SPAN function (current output 1).
5.4.2 Device and process variables
Device variables:
The following device variables are available using the HART protocol:
Process variables:
At the factory, the process variables are assigned to the following device variables:
• Primary process variable (PV) → Mass flow
• Second process variable (SV) → Totalizer 1
• Third process variable (TV) → Density
• Fourth process variable (FV) → Temperature
!
Note:
You can set or change the assignment of device variables to process variables using
Command 51 (see Page 42).
