The FB DECOUPLE input variables are linked using the 'DecIn(x)' buttons.
The FB DECOUPLE output variables are linked using the 'DecOut(x)' buttons.
The ‘MapState’ and ‘MapDiag’ checkboxes are used to specify which FB diagnostic functions are mapped
to the cyclic process image.
The FB DECOUPLE does not supply any error information and therefore the error button is basically
deactivated.
