Figure 1-10: Class B network data riser wiring using copper wire
Note:
As a matter of convention, a Class B network data riser
should start at the CPU module that does not have wires
connected to its Network A port.
When wiring a Class B network, give careful consideration as to
the location of the service panel. The service panel provides a
single point from which you can download files to all other
panels on the network. For this function to work properly you
must use the panel at the start of the network data riser as the
service panel. See “Downloading data files” for more
information.
Class A network data risers
In a Class A network, a single break or short in the network data
riser wiring does not interrupt communications between panels.
Figure 1-11 shows the wiring for a Class A network.
