Analog Input function block /
Description
Definition of the measuring range (lower and upper limit), the
physical unit and the number of decimal places for the output value
OUT.
Factory setting:
0...100 %


Note!
• The measuring range definition in this parameter group does not
limit the output value OUT. If the output value OUT is outside the
measuring range, the value is still transmitted.
• If "Direct" was selected in the L_TYPE parameter, the settings for
the measuring range and unit must be identical to those in the
XD_SCALE parameter group. If this is not the case, the function
block does not switch to the AUTO operating mode. The
"BLOCK CONFIG ERROR" block error is then displayed in the
BLOCK_ERR parameter.
Displays the process variable used for the block execution,
including the status of the process variable.


Note!
The unit used is copied from the OUT_SCALE parameter group.
Entry of the filter time constant (in seconds) of the digital filter of the
1st order. This time is required in order for 63% of a change in the
FIELD_VAL parameter to have an effect on the value of PV.
The diagram shows the signal curves of the Analog Input function
block over time:
a) The FIELD_VAL parameter changes.
b) The PV parameter has reacted 63% to the change in the
FIELD_VAL parameter.
Factory setting:
0 s
