Ethernet presently has a market share of over 80 % with a tendency to rise further, thus placing it in pole position in the global LAN landscape. Ethernet offers important characteristics that can give you significant advantages for your application:

• Fast commissioning through simple connections
• High flexibility since existing networks can be extended without any adverse effects
• High availability thanks to redundant network topologies
• Almost unlimited communications performance because scalable performance is available through switching technology if required
• Networking of different application areas such the office and production areas
• Investment security through continuous compatible further development
• Plant-wide clock system permits exact assignment of events within the complete plant

Ethernet technology for industrial environment

With Industrial Ethernet, SIMATIC NET expands the Ethernet technology by future-oriented network components with special properties and capabilities for use in industrial environments, e.g.:

• Rugged design, suitable for harsh industrial environments
• Fast local assembly using the FastConnect cabling system with RJ45 technology
• High fault tolerance through redundancy and fast switchover to redundant system (max. 300 ms)
• Continuous monitoring of network components through a simple yet effective signaling concept
