2.10 Surge protection
Surge voltages are extremely high voltages that can interfere with or even destroy
the insulation and function of electrical and electronic components.
Your machines and systems are therefore safeguarded against:
• Lightning strikes
• Switching operations (direct and indirect effects)
Be sure to:
• Spatial separation of systems that have different rated voltages
• The correct protection classes of surge protection modules
2.10.1 Protocols (Ethernet)
Use Industrial Ethernet protocols. This ensures the real-time behavior and
determinism in your plant. The most common protocols are:
• PROFINET

• EtherNet/IP
http://www.odva.org
• EtherCAT

• Ethernet Powerlink

• Modbus TCP
