Network Connection
For a TP/FT-10 channel, the network connection (from the NETP and NETN pins) is polarity
insensitive. Therefore, either of the two twisted pair wires can be connected to either of
these network connections.
For any of the supported cable types, the average temperature of the wire must not exceed
+55 °C, although individual segments of wire can be as hot as +85 °C.
As a general rule, TP/FT-10 network channel communication cables should be separated
from high voltage power cables. Follow local electrical codes with regard to cable placement.
Network Topology Overview
The TP/FT-10 network is designed to support free topology wiring, and can accommodate
bus, star, loop, or any combination of these topologies. Series 6000 devices can be located at
any point along the network wiring. This capability simplifies system installation, and
makes it easy to add devices if the network needs to be expanded. Figure 36 through Figure
40 present five different network topologies. The actual termination circuit varies by
application.
