Construction Of The Network: Notes

The network is made up of a number of control modules which are connected to each other serially via two communication cables. Each control module is supplied with power and grounded individually and receives messages / commands via the two communication cables. In both networks the control modules are connected to a number of different spurs. In the event of an open-circuit those control modules beyond the open-circuit will not be able to communicate with other parts of the network. However, a failure in one of the spurs can lead to communication failure with one control module while communication in the rest of the same network is working.
