10.4 CONTR: Controller
This main group determines the controller structure and function, which is used as starting point for
controller configuration for a particular application. The main controller configuration C.100 leads to
an input and output pre-adjustment (C.180.. C.190, C.500.. C591). This ‘proposal’ must always be
checked before commissioning and corrected, if necessary. After determination of this word, no
further settings are required for a large number of applications. Additional function adaptions are
possible via configuration words C.105 and the following configurations.
Main controller configuration 1:
CFunc CType WFunc
(Control behaviour) (Controller type) (Set-point function)
00: signaller 1 output
