An active bypass system comprising an active bypass module comprising: a first receiver connected to a first transmitter; and a slave node comprising a second receiver, a second transmitter, and a process node connected therebetween; wherein in normal operation data received by the first receiver is passed to the second receiver, and then passed to the process node for processing, after which a response is passed from the process node to the second transmitter, and then passed to the first transmitter, and in the event of a failure of the slave node, data is received by the first receiver and then passed to the first transmitter, thereby bypassing the slave node. w |
