System and method for maintaining proper termination and error free communication in a network bus

摘要

A system for maintaining proper termination and error-free communicaton in a network bus (12) including a power bus includes at least one network device (18), a network controller (16) and at least on bus protection element. The network devices (18) are electrically connected to and adapted to communicate via the network bus (12). The network controller (16), in turn, is electrically connected to the network bus (12) and is adapted to direct communicaitons with the network devices (18) via the network bus (12). The network controller (16) is also adapted to provide power signals to the network devices (18) via the power bus of the network bus (12). The network controller (16) and/or the bus protection elements can monitor signals on the network bus (12). And based upon the network controller (16) and/or bus protection elements identifying a predefined number of improper signals, the bus protection elements can selectively connect and disconnect respective network devices (18) to and from the network.
