Abstract: A systematic description of the interaction between two systems is presented within the framework of thermodynamics of discrete systems. We distinguish between two situations: a contact between an equilibrium system and a non-equilibrium one, and a contact between two non-equilibrium systems. In the second case the state space includes replacement quantities, which reduce the situation to a contact between an equilibrium system and a non-equilibrium one. Interacting discrete systems form a composite (compound) system which is also a discrete one. Thus a compound system can be described as if it were composed of two subsystems, or by ignoring this fact, as a plain single discrete system, whose composition of sub-systems is not taken into consideration. These descriptions cause different degrees of accuracy which are expressed by excess quantities. Such an excess quantity vanishes if the discrete system is really not composed of subsystems. Aim of this paper is to calculate the excess quantities of power and energy exchange and to derive the excess entropy in the special case of an endoreversible compound system.
