9. Installation - Shielding & Grounding
Improves EMC behavior
Provides a low impedance (short) return path for noise and current
Reduces the emission from the bus
!!!
Shield is not always connected to protective GND within the devices; therefore, make sure the cable shield will be connected to GND before it enters or leaves the cabinet

For the installation of a PB network, you can use shielded twisted pair copper cable, glass or plastic FO and infrared components. And you can mix these components for one network.
Although stub lines can theoretically be tolerated at the
lower baud rates, the recommendation is to avoid the use
of stub lines altogether.

1. How to hold the insulation
stripper in your right hand.
2. Match up the cable end with the template so that your left index finger is against the end surface of the tool. 4x

4. Clamp the cable firmly in the stripper.
5. Rotate the stripper around
the cable 4 times in the
direction of the arrow.
6. With the clamp still closed,
pull the stripper off the end of
the cable.

18. Wiring - Easy, when you use the right tools...
7. The removed insulation
remains in the stripper. After
releasing the clamp, the
remnants can be removed.
8. Pull the protective foil off the
cores.
9. After removing the insulation
from the cores, the cable can
be fitted into the PB connector.
Notes:
The PROFIBUS cable is normally wired through the device, under some circumstances this is not possible and terminal blocks are used to connect via a spur line or drop line to the device. By using baudrates higher than 1.5 MBaud the use of these terminals is not allowed.

Plastic, PCF and glass fiber optic available
Plastic - 50m between 2 Optical Link Modules (OLM)
PCF - 300m between 2 OLMs
Glass - up to 15km between 2 OLMs
Connections via modules or integrated interface
When is Fiber Optic the Choice?
Noise immunity & independence from potential differences
Cover longer distances
Line, ring and star configuration possible
Media redundancy
Notes:
As an alternative, PB can use FO for wiring. The advantages are:
you don’t care about EMC
you don’t care about potential differences
you can extend the covered distance tremendously
media redundancy is possible
different topologies
