Example of a PID controller
Figure 130:Wiring the function block coils
The function block coils are activated by markers.
Figure 131:Wiring the contacts
The message of the function block is sent to a marker.
Parametric programming of the function block inputs/outputs
When using the function block in the circuit diagram for the first time, use
OK to automatically enter the general display of function block parameters,
as shown in the figure on the left. Enter the function block settings here.
The display contains the following elements:
Coils
Function
DC..EN
Selective activation of the function block
DC..EP
Activation the proportional function
DC..EI
Activating the integral function
DC..ED
Activating the differential function
DC..SE
Activating the manual manipulated variable, manual mode
