P1 i P amplification
I4 b Master Reset P2 i Integral time in ms
Description:
The control deviation (I1- I2) is multiplied by the amplification P1. The I controller adds up the
control deviation over time. The I component is added. When the integral time has elapsed, the
I component reaches the same value again so that the output value is doubled.

The output value is limited to the value at input I3.
As long as status TRUE is present at I4 (Master Reset), the output value I1 and the I compo-
nent are 0.
Note:
Percentages [%] have two decimals.
For example: Value 12345
