The SCALANCE X-200IRT PRO 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 topology, isochronous mode for motion control applications and unlimited IT openness have been satisfied for the first time within a single technology based on the PROFINET standard.

The switches with IP65 protection are designed for cabinet-free mounting (PROFINET-compliant push pull connection technology).

Real-time Ethernet

• Interfacing of the PROFINET IO Devices to the PROFINET IO 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 procedure of the IEEE 802 standard by combining the switching mechanisms "Cut Through" and "Store and Forward"
• For drive controls, PROFINET with isochronous real-time is the best performing system worldwide with regard to its isochronronous and deterministic response.
  With a cycle time of 1 ms, for example, axes can be controlled in isochronous mode whereby 50% of the bandwidth is available solely for IT communication.
