Abstract
A communication bus containing master and slave devices includes a monitor unit for fault tolerant communications. In the event the master is unable to communicate, the monitor automatically assumes the master communication role. When more than one monitor is connected within the communications network, the monitor with the lowest communications address assumes the master communications role. The master includes software implementation that allows an operator to obtain data from any of the slave devices via the monitor.
