Parameter lists
AI FB:
MODE_BLK (5)
Storage class S; read/write capability r/w; supported modes ALL
Operating mode of AI Function Block
– Target Mode
– Actual Mode (read only)
– Permitted Mode
– Normal Mode (read only)
•
AUTO · The analog input value (FIELD_VAL) is processed by the function block and
issued as OUT.
•
MAN · The output value of the AI Function block can be entered manually by the
operator over the OUT parameter.
•
O/S · The AI Function Block is not executed. The last value is issued at the output OUT.
AI FB:
OUT (8)
Read/write capability r/w; supported modes M
Primary analog value calculated as the result of the function's execution
•
Output value in the OUT_SCALE unit
AI FB:
OUT_SCALE (11)
Storage class S; read/write capability r/w; supported modes O
Range of the analog OUT value (start, end, unit and decimal point)
•
[0 to 100 %]
AI FB:
PV (7)
Read capability r
Process variable of the function block (value and status)
•
Unit from the XD_SCALE parameter group.
AI FB:
PV_FTIME (18)
Storage class S; read/write capability r/w; supported modes ALL
Time constant of a single exponential filter for PV
AI FB:
SIMULATE (9)
Read/write capability r/w; supported modes ALL
Simulation · Discrete input value (FIELD_VAL) with status
Note:
The simulation can only be activated if it is enabled at the positioner (Code 48 F3)
and in the function block.
