Installation Drop Lines Cable Distances Termination Shielding & Grounding Notes: 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.

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 Notes: 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.

Installation - Cable Distances >= 20 cm Cable Category I Cable Category II Cable Category III >= 10 cm >= 10 cm >= 50 cm >= 50 cm >= 50 cm Cable Category IV Notes: 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.

Installation - Cable... (continued) Category I: LAN cables (e.g. Ethernet) Other communication cables Category II: Shielded and unshielded cables for DC voltages > 60V and <= 400 V Shielded and unshielded cables for AC voltages > 25V and <= 400 V Category III: Shielded and unshielded cables for DC and AC voltages > 400 V Category IV: Signal cables of categories I - III at risk from direct lightning strikes, e.g., connections between components in different buildings Notes: 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.

! Manufacturer ! Installation - T-Connections (Drop/Stub/Spur) Every branch or drop directly from the cable Stubs to devices cause reflections (additional capacitance) Repeaters are not spur-lines Device Device RS485 RS485 Notes: 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. ! Manufacturer ! Internal to device Between device and trunk line (A) (B)

Installation - T-Connections (Drop/Stub/Spur) For Drops above 187.5kBaud: use Bus Terminals or Repeaters Notes: 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.

Wiring - Easy, when you use the right tools... 3. Insert the end of the cable into the stripper using your left index finger as a limit stop to ensure the correct length is inserted. 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 Notes: 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. 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.

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. green wire A red wire B PROFIBUS wiring terminal block drop line Device

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
