IP communication

Conventional IP communication, for example e-mail, web services or proprietary real-time protocols from third parties, are handled outside the SERCOS III telegrams in a so-called NRT (non-realtime) channel. This unencrypted IP channel, which sits directly on top of the Ethernet layer, has a number of advantages:

• Slave test and configuration without initialized real-time Ethernet and master hardware
• Direct addressing of SERCOS III devices by means of the MAC or IP address
• Standard Ethernet devices such as laptops can be connected directly to SERCOS III devices via any free SERCOS III port
• Full computational performance for the application, because the master does not have to encrypt or fragment the IP packages
