3. Enter the setpoint for the controller.
4. Select the "input" and "output" for the actual value and the controlled variable
respectively. You hereby specify that the values from one tag of the user program are to
be used.
Note
Input(_PER) - Output(_PER)
Use input and output to supply the input or output parameters with the actual value of the
user program. Use Input_PER and Output_PER to use an analog input as actual value or
an analog output as manipulated value output. Use Output_PWM to use a digital
switching output that is controlled via pulse width modulation. The manipulated variable is
formed by variable on/off times in this case.
