The SCALANCE XF204IRT Industrial Ethernet switch permits the construction of isochronous real-time (IRT) Industrial Ethernet line and star topologies. 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 are satisfied within a single technology based on the PROFINET standard.

Features:

• Device diagnostics with LEDs (power, link status, data communication)
• Remote diagnostics is possible through signaling contact (signal mask can be set locally using buttons), PROFINET, SNMP, and web browser
• Automatic e-mail send function
• The RJ45 sockets are designed to be industry-compatible with additional sleeves, for connection of the IE FC RJ45 Plug 180

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

Additionally 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.
  For example, with a cycle time of 1 ms, axes can be controlled in isochronous mode while 50% of the bandwidth is available at the same time for IT communication without restriction.
