2300 series managed TSN switches

Time Sensitive Networking (TSN) describes a series of standardized transmission mechanisms for data in Ethernet networks that allow deterministic real-time communication, regardless of the protocol. Precise time synchronization is the basis for combining hard real-time requirements and classic IT services in one network – the basis for network convergence.

With the managed TSN switches from Phoenix Contact, you build applications with precise time synchronization. This ensures real-time communication and increased availability in your automation networks.

TSN – the new Ethernet technology

Time-Sensitive Networking is a set of standards designed to improve the real-time properties of current Ethernet networks. This is therefore made of several individual standards that are currently being defined in the TSN Task Group of the IEEE 802.1 standardization organization.

However, Ethernet TSN is not an independent communication protocol. Instead, it defines functions. These functions can in turn be used by different protocols such as OPC UA and PROFINET.

Communication standards

Reliable standard in the age of Industry 4.0

The managed TSN switches support the PROFINET TSN profile

The 2300 series TSN switches support the PROFINET TSN profile:

  • IEEE 802.1AS (precise time synchronization)
  • Frame preemption
  • Stream management via PROFINET

The TSN mechanisms increase the performance, robustness, and availability of current networks.

User-friendly TSN configuration

Easy PROFINET TSN configuration

TSN configuration made easy

The FL SWITCH TSN 2300 devices allow a user-friendly TSN configuration via PROFINET 2.4 engineering. Here, the configuration of isochronous data traffic is easier than with classic PROFINET RT.

2300 series Managed TSN Switch

FL SWITCH TSN 2300 – for introducing TSN without device replacements

Proven and future-proof in one device

Supporting all functions of the 2300 series FL SWITCH, the devices can also be used in classic applications. Use the FL SWITCH TSN 2300 to migrate your current network solution into state-of-the-art TSN architectures.
