The SCALANCE X-200IRT Industrial Ethernet switches permit the construction of isochronous real-time (IRT) Industrial Ethernet line and star topologies. Ring structures can also be designed using the integral redundancy manager (RM). Redundant ring connections are also possible. Thanks to innovative switching technology, the special requirements of automation with regard to line topologies with fast data communication and simultaneous compliance with isochronous mode for motion control applications and unlimited IT openness within a single technology have been satisfied, based on the PROFINET standard.

The switches with IP30 degree of protection have been designed for use in the control cabinet.

Real-time Ethernet

• Interfacing of the PROFINET devices to the PROFINET controller through high-performance, optimized data transmission
• Coexistence of isochronous mode for motion control applications and IT openness:
  Reaction-free transmission of real-time and non-real-time communication on the same line

Also through isochronous real-time (IRT) Ethernet

• Isochronous real-time communication based on the transmission method of the IEEE 802.3 standard by combining the "Cut Through" and "Store and Forward" switching mechanisms
• For drive controls, PROFINET with isochronous real-time is one of the best performing systems worldwide with regard to its isochronous and deterministic response.
  With a cycle time of 250 µs and a jitter of less than 1 µs, axes can be controlled in isochronous mode leaving 50% of the bandwidth available without restrictions for IT communication, for example.
