ALTERNATING COMMUNICATION CHANNEL SWITCHOVER SYSTEM ABSTRACT OF THE DISCLOSURE A redundant common communication: system for a distributed process control or data processing system has multiple stations which are coupled to at least two redundant communication channels such as communication busses Each station includes a transmitter for transmitting data packets and a receiver for receiving data packets. Each data packet includes a channel selection field which identifies a selected channel to be used by all station during a succeeding transmission of a data packet. Each station makes an assessment of quality of each channel based upon the occurrence of errors when that channel is in use. The station computes a margin value based upon assessed quality factors. When the station gets an opportunity to transmit, the channel selection field of the transmitted packet identifies a channel which is selected based upon the margin value and the frequency of previous use of each of the channels. As a result, frequent switching among the channels occurs, with the percentage of use of each channel being dependent upon the assessed quality of that channel by the various stations
