A vital serial link for linking a plurality of data processors 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, one for each direction of transmission, in the vital serial link, each controller including a means for storing a plurality of link parameters, 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 said 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 said network was the signal originating processor. The link further includes communicating means for communicating signals, including the link parameters, between the data processors of the network.
