Transmission media
AS-Interface
One feature of AS-Interface technology
is the use of a common two-wire cable
for data transmission and for the
distribution of auxiliary power to the
sensors/actuators. For this purpose, an
AS-Interface power supply unit is used
which fulfills the requirements of the
AS-Interface transmission method.
The mechanically coded and therefore
non-interchangeable AS-Interface profiled
cable is available for wiring purposes. The
repeater/extender is used to extend an
AS-Interface segment.
PROFIBUS
For PROFIBUS, different transmission
media are available for a wide variety of
applications.
Electrical data transmission
The standard solution for this form of
data transmission is a shielded, twisted
pair cable with circular cross section.
These cables are available with PE or PUR
sheath, in a halogen-free version,
designed for underground installation or
as dragline, or in a special version for use
in hazardous areas.
The PROFIBUS FastConnect ® system (FC)
allows the PROFIBUS copper cables to be
prepared quickly and easily on site.
Optical data transmission
This solution is based on fiber-optics.
The FO cables are available with glass or
plastic fibers for indoor or outdoor use,
in a dragline version, and in a halogenfree
version.
Wireless data transmission
This form of transmission is based on
ILMs (Infrared Link Modules) with a reach
of 15 meters.
Industrial Ethernet
Electrical data transmission
• FC twisted pair
The FC twisted pair cabling system is
ideal for structured cabling in the plant
itself. The FastConnect(FC) connection
system for Industrial Ethernet not only
"industrializes" the structured cabling
system from the office area for use in
the plant. FastConnect cables can also
be prepared extremely quickly right
on site, thus making standard RJ45
cabling technology available in an
industry-standard version suitable for
structured cabling (patch, patchfield,
interior, outlet, service cabling).
Thanks to integrated insulation
displacement contacts (such as ELS
TP40), a connection is possible between
two nodes up to 100 meters apart using
FC TP cables without additional patching.
If electrical isolation and EMC protection
are the primary concerns, however, then
optical data transmission would be the
right solution.
Optical data transmission
• Glass fibers
The optimum technology, even for
setting up redundant ring networks.
Futuristic fiber-optics cables, which are
completely impervious to electromagnetic
interference, are used as transmission
medium. These cables are
also completely free from potential
dependencies. The advantage:
absolutely no need to invest in
expensive equipotential bonding.
Wireless data transmission
To allow wireless data transmission, a
local radio network for wireless
communication can be set up with just
an Access Point, such as RLM, and a radio
card, e.g. the CP 1515.
These transmission media can also
be used in any combination.
