The modeling, simulation and verification language (MSVL) is a temporal logic programming language as well as an executable subset of projection temporal logic (PTL). MSVL and PTL are used for modeling and verifying properties of concurrent systems. However, MSVL lacks a mechanism of communication based on message passing which is essential for modeling and verifying concurrent distributed systems. This paper shows how to develop and implement a suitable mechanism in MSVL to model and verify concurrent distributed systems. First, channel structure is defined while communication statements and process structures are formalized. Then, the implementation mechanisms for those communication statements are presented. Finally, a modeling and verification example involving an electronic contract signing protocol is provided to illustrate how the message passing works in MSVL.
