PURPOSE: An IPC(Inter Process Communication) method in a CASS(Connector for Agent and Switching System) is provided to solve a problem that an HMI(Human Machine Interface) server is influenced by a CASS and re-start the HMI server even though a CASS processes are all normally operated in case that the HMI server is abnormally terminated by allowing an IPC communication using an FIFO(First Input First Output) instead of a message queue between threads. CONSTITUTION: An FIFO class is defined to have a member function of the same name as that of a member function for reading a message provided when a message queue is used(S32). An FIFO class is defined to have a member function of the same as that of a member function for writing a message provided when the message queue is used(S34). The message queue class is substituted with the FIFO class and the substituted FIFO class is inputted(S36).
