This enables adaption of the 3-Point controller to two different actuators for outputs + and -. External pa-
rameter switching is not applicable here.
3-Point step controller = step controller for I-actuators with 3PntPW output
In conjunction with the down-line integrating actuator, the internal controller “Step” simulates a continu-
ous controller and has a 3-Point output with feedback. It is thus only suitable for use in combination with
integrating actuators, such as motor actuators.
(The operational characteristics of “Step” correspond to those of Pleiger controller 362-D)
Continuous controller = controller with continuous output.
The controller output of the continuous controller “Cont” is supplied to the assigned analogue output.
The required hardware configuration of the 362MC is to be observed.
(The operational characteristics of “Cont” correspond to those of Pleiger controller 361-D).
Cascade step controller = internal interconnection of 2 controllers to create the cascade controller
“CscStep”. Controller output Y
1
of the primary controller, with setpoint W and actual value X, is injected
into the secondary controller as setpoint V. In addition to the controlled setpoint V, the secondary 3-Point
step controller also receives secondary actual value U to form output Y
2
.
With setpoint gain KW

of the secondary controller can be employed, for example, to bypass the primary
controller during commissioning (Kr

results in W=V).
