Description of the regulation functions
Programming a regulation function
Programming rules
The regulation function parameters must all be informed. The functions use 3 kinds l l l of parameters: read only parameters, considered at the beginning of the function’s execution, write only parameters, positioned at the conclusion of the function’s execution, the read and write only parameters, whose contents are considered at the beginning of the function’s execution, are then updated by the results of the function.
Note: The regulation functions must be programmed in a periodic task (MAST periodic or FAST). They must not be conditioned.
Parametering The word type input parameters are the analog sizes expressed in the scale [0,
+10000] and can be directly connected to measurement sensors via the words
%IWxy.i des analog inputs.
The bit type output parameters support ordering discrete actuators and can be directly connected to the %Qxy.i. type variables.
In the same way, the word type output parameters support ordering of analog actuators on the scale [0, +10000] and can be directly appointed to the %QWxy.i. type variables.
The MWi:L word table type parameters regroup the user parameters and the data necessary to the internal working of the function.
If the length of a table is sufficient, the function is not executed.
Note: In order to keep the adjustment parameters of the OF adjustment on cold start, it is necessary to delete the %MWi reset to zero option (in the processor’s configuration screen).
