Abstract:
1. A communication message conversion apparatus that converts a message of an event-triggered communication protocol into a message of a time-triggered communication protocol and communicates with a designated address, comprising: reception unit that receives the message of the event-triggered communication protocol; a transmission buffer that stores the message of the time-triggered communication protocol; a transmission unit that transmits the message of the time-triggered communication protocol stored in the transmission buffer to a communication path with a time-triggered schedule; and a routing unit that updates the message of the time-triggered communication protocol in a designated address storage location of the transmission buffer with the received message of the event-triggered communication protocol and stores updating history which indicates whether or not the message of the time-triggered communication protocol of the designated address storage location is updated in the transmission buffer, the updating history being attached to the message of the time-triggered communication protocol, wherein the transmission unit transmits the message of the time-triggered communication protocol with the updating history attached.
