2-2 Installation
SCANport Cables
When selecting the SCANport cable to connect the module to the
SCANport product, you need to:
• Use an Allen-Bradley SCANport cable. Refer to the table below.
• Do not exceed 10 meters (33 feet) of cable between the
SCANport product and module.
• Keep SCANport cables away from high power cables to guard
against introducing noise into your system.
ControlNet Cable Taps
A tap connects a node on the ControlNet network, such as a module,
to the cable system via an integral 1 m (39.6 in.) drop cable. When
selecting a tap to connect the module to the ControlNet network, you
need to:
• Determine if your network uses a redundant media system. If so,
you will need two taps.
• Use one or two Allen-Bradley tap(s). Refer to the table below.
For more information on ControlNet taps and ControlNet networks,
refer to Publication 1786-6.2.1, ControlNet Cable System Planning
and Installation Manual.
