<p>A vital serial link for linking a plurality of data processors (unit 10) which act on information communicated in the form of link information signals, into a vital serial communications network, including at least two vital serial controllers (unit 21), one for each direction of transmission, in the vital serial link, each controller including a buffer memory for storing a plurality of link parameters (units 16T and 16R), each of the link parameters including a numerical relationship indicating that a specified first processor originated a signal and that a designated second processor is to receive the signal, a unique numerical relationship being provided for each possible combination of signal originating processor and signal receiving processor; whereby, upon receipt of a signal, the signal receiving processor can discriminate signals sent to the receiving processor, and determine which processor in the network was the signal originating processor. The link further includes communicating unit for communicating signals, including the link parameters, between the data processors of the network.</p> |
