Loop error at the time n;
generally applies: e = SP –
PV
SP
The parameter SP is the set-value
assignment w. For this parameter you
can use the analog output of a
different special function.
-10,000 to +20,000
PV
PV is the process value x and is
calculated as follows:
PV = (analog value on input * gain) +
offset.
You can connect the input for
example by means of an analog input
with a PT100 sensor.
"
The gain parameter has an effect on
PV
0.0 to 10.0
The offset parameter has an effect on
PV
-10,000 to +20,000
PV is restricted by the parameters
Min. and Max.
In each case: -10,000 to +20,000
