No more message frame delays

A variety of solutions for Industrial Ethernet networks are available for critical applications with high-availability requirements that do not permit any additional delay in communication.

The managed SCALANCE X-200RNA Industrial Ethernet network access points with PRP functionality (Parallel Redundancy Protocol) or HSR functionality (High Availability Seamless Redundancy Protocol) according to IEC 62439-3 provide redundant network structures.

Ideal for the production or process automation but also used in substation applications for electrical power distribution, for example, in medium- and high-voltage switchgear.


  • High-availability system solutions for bumpless and seamless data transmission according to standard IEC 62439-3
  • Suitable for parallel networks and ring structures
