Function "set unit to bus" (062), PROFIBUS PA only
Selection:
•
confirm
After confirming this function, the unit of the measured variable is taken over in
the AI block (PV scale
Out scale).
This function must always be executed after changing the unit.
"
Caution!
This function is available for PROFIBUS PA devices only!
8.7
Function "curr. output mode" (063), HART only
In this function you specify the mode of the current output.
Selection:
•
standard
•
curr. turn down
•
fixed current
standard
The total measuring range (0
%
... 100
%
) will be mapped to the current intervall
(4 mA ... 20 mA).
curr. turn down
Only a part of the measuring range will be mapped to the current intervall
(4 mA ... 20 mA).
Use the functions
"4 mA value" (068)
and
"20 mA value" (069)
to define the
concerning range.
fixed current
The current is fixed. The measured value is transmitted by the HART signal only. The
value of the current is defined in the
"fixed current" (064)
function.
"
Caution!
This function is active for HART devices only!
