FB_BA_MO_IO

The function block FB_BA_MO_IO represents the Multi-State_Output object.
It has a priority array and can therefore be commanded (see Commanding objects).

The Multi-State_Output object specifies an object type whose object properties represent externally visible characteristics of a data point for multiple binary outputs, connected by arbitrary binary logic. The object is derived from physical or virtual data points, e.g. for "active/inactive" states of several binary outputs or the value of an analog output.
