A method for monitoring and controlling a plurality of heterogeneous devices of a technical facility, each device being able to receive and/or deliver at least one piece of information (18, 40), the method being characterized in that it includes the following steps: - translating, via a central unit that supervises the operations and interactions of the various devices, each piece of information into a class of independent abstract objects independent of the physical characteristics of said devices, the translation consisting of classifying each piece of information either as a binary physical property capable of assuming two distinct states, or as a variable physical property capable of assuming several distinct values in a continuous value interval, or as a physical property assuming a formatted frame form, each object class being defined as a function of inherent properties stored beforehand in an abstraction knowledge base, - associating each abstract object class with a data category able to be interpreted automatically, - applying, to each data category, by said central unit, at least one specific processing operation from among a plurality of predefined processing operations allowing centralized supervision of the operations and interactions of the various devices, - defining behavior parameters of said information as a function of measurable extreme values (EMmin, EMmax) of said physical property, the measuring precision of said property, the Pitch associated with each value change of said property, the conversion formula of a measured value of said property into a value usable by a processing unit, - defining inherent properties of the physical property as a function of its current value EMn measured at a moment n, its previous value EMn-1 measured at a moment n-1; its current value ECn converted at a moment n, its previous value ECn-1 converted at a moment n-1, the measured current time code Tn, and the previous time code Tn-1. - translating, via a central unit that supervises the operations and interactions of the various devices, each piece of information into a class of independent abstract objects independent of the physical characteristics of said devices, the translation consisting of classifying each piece of information either as a binary physical property capable of assuming two distinct states, or as a variable physical property capable of assuming several distinct values in a continuous value interval, or as a physical property assuming a formatted frame form, each object class being defined as a function of inherent properties stored beforehand in an abstraction knowledge base, - associating each abstract object class with a data category able to be interpreted automatically, - applying, to each data category, by said central unit, at least one specific processing operation from among a plurality of predefined processing operations allowing centralized supervision of the operations and interactions of the various devices, - defining behavior parameters of said information as a function of measurable extreme values (EMmin, EMmax) of said physical property, the measuring precision of said property, the Pitch associated with each value change of said property, the conversion formula of a measured value of said property into a value usable by a processing unit, - defining inherent properties of the physical property as a function of its current value EMn measured at a moment n, its previous value EMn-1 measured at a moment n-1; its current value ECn converted at a moment n, its previous value ECn-1 converted at a moment n-1, the measured current time code Tn, and the previous time code Tn-1.
