Communications Loop Wiring Overview
The daisy chain is the best method for running a communications loop since there is only
one starting point and one ending point. See Figure 2-7.
Figure 2-7: Communication Loop Wiring, Daisy-Chain Configuration
Even though the daisy chain configuration is preferred, the star configuration can also be
used. If required, a combination of the two can also be used. Remember, the best comm
loop wiring is the one which utilizes the minimum number of ends while using the short-
est wiring path. See Figure 2-6 and Figure 2-13 for controller addressing information.
