About ControlNet
ControlNet is a high-speed, serial communication
system that provides for a time-critical exchange
of information between complex control devices
such as programmable logic controllers, HMIs
and PC-based controllers. ControlNet operates
in a totally deterministic and predictable
manner, allowing the various devices and
controllers on the network to communicate
at a precise and pre-determined point in time.
ControlNet Features
A ControlNet network can support up to 48
nodes at a bus speed of 5Mb/s on a total end-
to-end distance of 250m. The bus topology can
be star, tree, bus, or any combination of the
three. The time delay throughout the system
and a maximum end-to-end distance of 30+ km,
represent the only limiting factors on the
number of repeaters that can be used.
Although ControlNet uses a larger bandwidth
than other automation and control networks, it
does not function as a traditional “broadband”
network. In a ControlNet system, the network
devices and controllers are expected to
communicate/operate at a pre-determined
point in time and for a specific length of
time. Broadband communication networks
differ in that their communication efforts
take place when the network has room
for the communication.
Because ControlNet is deterministic, it is
robust and capable enough for industrial time-
critical applications. This core philosophy of the
system also requires that signal transmission be
uncorrupted and high speed. Therefore, choosing
an approved, tested and conformant Low-loss
RG-6 made especially for ControlNet systems
from Belden is truly important for maximum
system performance.
Quad-shielded ControlBus
Coaxial Cables
Belden ControlBus Low-loss coax cables
for ControlNet applications incorporate
a Duobond® IV Quad Shield for maximum
signal integrity and run length. All products
are sweep tested, ensuring that Return Loss,
and other critical performance features, meet
the requirements of the ControlNet physical
layer specification. New to the line is 183092A
—with continuously corrugated aluminum
armoring for added protection in harsh
environments. ControlBus cables can be
supplied with a CPE jacket and/or aluminum
or steel interlocked armoring. Belden also
manufactures variations of the cable for
different applications, environments, and
identification purposes.
