Process controller (option)

Figure 10 shows the function of the process controller:
The process controller (2) receives the process setpoint (E1) and the process
variable (E4) (e.g. from a sensor). On the basis of both values, the process
controller calculates the position setpoint (E7) for the positioner (3).
In turn, the positioner (3) compares this setpoint with the position feedback
(E2) of the valve and issues the operation commands (OPEN - CLOSE) to
the actuator.
