De - other communication system Messe - di control scheme

摘要

A message control method for a data communication system, comprising a loosely-coupled multiprocessing system in which a plurality of processing modules having a memory unit respectively are mutually connected through a system bus. For the message control method, each processing module (10, 40) consists of a central processing unit (11, 41), a memory unit (12, 42), and a connection unit (13, 43). The connection unit (13, 43) has at least a logical transmission port (21, 51) for transmitting messages, a logical reception port (22, 53) for receiving messages, transmission-system connecting means (23), reception-system connecting means (24), means (25) for monitoring trouble on the transmission side, and means (26) for monitoring trouble on the reception side.
