4.4.7 Continuous controller with integrated positioner ( Cntr/ C.Fnc = 6 )

( Cntr/ C.Fnc =6)

Basically, this controller function is a cascade. A slave controller with three-point

stepping behaviour working with position feedback Yp as process value (INP2 or

INP3) is added to a continuous controller.

ConF / Cntr SP.Fn = 0 setpoint controller

C.Fnc = 6 continuous controller with

position controller

C.Act = 0 inverse output action

(e.g. heating applications)

ConF / InP.2: I.Fnc = 3 position feedback Yp

S.typ = 50 sensor e.g. potentiometer 0..160 W

ConF / Out.1: O.Act = 0 direct output action Out.1

Y.1 = 1 control output Y1 active

Y.2 = 0 control output Y2 not active

ConF / Out.2: O.Act = 0 direct output action Out.2

Y.1 = 0 control output Y1 not active

Y.2 = 1 control output Y2 active

PArA / Cntr: Pb1 = 0,1...9999 proportional band 1 (heating)

in units of the physical quantity

(e.g. °C)

ti1 = 1...9999 integral time 1 (heating) in sec.

td1 = 1...9999 derivative time 1 (heating) in sec.

t1 = 0,4...9999 min. cycle tim 1 (heating)

SH = 0...9999 switching difference
