In this paper we introduce the notion of a P automaton with one-way communication, a concept related both to P systems and the traditional concept of automata. A P automaton with one-way communication is a purely communicating accepting P system. The result of the computation in these systems is the set of multiset sequences consumed by the skin membrane, supposing that the P automaton started functioning in an initial state and entered a so-called final state. As a result, we show that for any recursively enumerable language, a P automaton and a certain type of projection can be constructed such that the given language is obtained as the image of the set of accepted input multiset sequences of the P automaton.
