REAL TIME COMMUNICATION DEVICE AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a communication system capable of increasing processing performance regardless of the processing performance of a CPU. SOLUTION: A communication node is constituted of a communication controller 8 for transmitting information to be transmitted to a transmission line 9 by a transmission instruction and storing the information received from the transmission line 9 in a storage device 2 and a data processor for computing transmission time that the local communication node performs transmission, based on the received information and the information set to the local communication node beforehand by the detection of the write of the information received by the communication controller 8, counting the computed transmission time from the point of detecting the end of the write by the communication controller 8 and informing the communication controller 8 of an instruction for transmitting the information from the local communication node.
