he LOGO!, the parameter KC applies as an increase for
the I part and the P part of the controller equally
Should you enter KC=0, then the P part of the controller
switches off. In this special case, k is automatically set to 1
for the I part.
If KC = 0: kP = 0 and kI = 1
If KC ≠ 0: kP = kI = KC

SP The parameter SP is the set-value assignment w. For this
parameter you can use the analog output of a different
special function.
-10000 to +20000
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
-10000 to +20000
PV is restricted by the parameters Min. and Max. In each case:
10000 to +20000
The Dir parameter gives the action direction of the control-
ler.
Positive means: If set value > process value then the pro-
cess value is increased; if set value < process value then
the process value is reduced.
Negative means: If set value > process value then the
process value is reduced; if set value < process value then
the process value is increased.
Example, heat regulation: if the set value is greater than
the process value (room is too cold), the manipulated vari-
able increases the process value.
