A control system with redundant connections allowing to detect wrongly configured addresses

摘要

A control system comprises: a plurality of input devices; a plurality of remote output devices; a plurality of dedicated connections and a digital data network interconnecting the plurality of input devices and the plurality of remote output devices. Each one of the plurality of output devices is connected to one of the plurality of input devices by an associated one of the plurality of dedicated connections. Each output device is operable to detect an addressing error in the digital network by comparing a value of a parameter received via its dedicated connection with the value of the same parameter received via the digital data network. The addressing error can be fixed by selecting one of several pre-configured addresses based on comparing values transmitted by the dedicated connection and the digital data network. <IMAGE>
