The daisy chain is the best method for running a communications loop since there is only
one starting point and one ending point for each of the communications loops. 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
communication 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 the 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.
Make sure CommLink jumper is set for “Multi”.
