Wire/Cable Types Chapter 1
ControlNet
ControlNet cable options, topology, distances allowed, and techniques are
specific to the ControlNet network. For more information, refer to the
ControlNet Coax Media Planning and Installation Guide, publication
Depending on the environment at the installation site, there are several types of
RG-6 quad shield cables that can be appropriate. The standard cable
recommended is Allen-Bradley catalog number 1786-RG6, Quad Shield coax.
Country, state, or local codes, such as the U.S. NEC, govern the installation.
The allowable length of segments and installation of terminating resistors play a
significant part in the installation. Refer to the ControlNet Coax Media
Planning and Installation Guide, publicat
, for details.
Ethernet
Ethernet communication interface wiring is very detailed for the type of cable,
connectors, and routing. In general, Ethernet systems use shielded twisted pair
(STP) cable, or unshielded twisted pair (UTP) cable, with RJ45 connectors that
meet the IP67 standard and are appropriate for the environment. Use cables that
meet Telecommunications Industry Association/Electronic Industries Alliance
(TIA/EIA) standards at industrial temperatures.
Shielded cable is recommended when the installation can include welding,
electrostatic processes, drives over 10 Hp, motor control centers (MCCs), high
power RF radiation, or devices carrying current in excess of 100 A. Shield
handling and single-point grounding, also discussed in this document, are also
important for the proper operation of Ethernet installations.
There are also important distance and routing limitations published in detail.
