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
shortest wiring path.
Note: The loop does not have to follow the controller address sequence.
Caution: If comm loop is not installed in conduit be careful to position the cable
away from high noise devices like fluorescent lights, transformers,
VFD’s, etc. Conduit is not required for comm loop wiring unless
required by local codes.
