The Beckhoff ET2000 Industrial Ethernet Multi-Channel Probe is a specialised diagnostic tool for monitoring, analysing, and troubleshooting Ethernet-based communication in industrial automation systems. Designed with four independent channels and eight total ports, it enables engineers to capture traffic across multiple network segments simultaneously, providing a complete view of system behaviour in real time.

Unlike conventional Ethernet switches, the ET2000 is a passive probe, meaning it introduces virtually no interference into the monitored network. With an ultra-low forwarding delay of approximately 1 microsecond, it ensures that live traffic is not disrupted while still delivering an accurate representation of network communication. This makes it especially valuable for monitoring real-time industrial protocols such as EtherCAT, PROFINET, Ethernet/IP, and Modbus TCP.

Each channel can be connected via the probe’s MII/RJ45 ports, and data is forwarded to a host PC through the dedicated 1 Gbit/s uplink port. This high-speed uplink ensures that even heavy traffic loads can be mirrored and analysed without packet loss, making it reliable for capturing large volumes of communication data in complex installations.

A standout feature of the ET2000 is its high-resolution timestamping capability. Channels 0 and 1 support timestamps with 1 ns accuracy, enabling engineers to precisely measure delays, jitter, and synchronisation behaviour. This level of precision is particularly important when analysing deterministic networks like EtherCAT, where microsecond-level deviations can affect control system performance.

For analysis, the ET2000 works seamlessly with WinPcap-compatible software tools, such as Wireshark. Engineers can use familiar packet capture and analysis platforms to filter, decode, and visualise traffic data, allowing efficient troubleshooting and performance optimisation.

The unit is designed for industrial-grade deployment, operating reliably in environments with temperatures ranging from 0…55 °C. Its compact housing makes it suitable for both laboratory and field use, while its straightforward connection scheme ensures quick setup during commissioning or maintenance.

Typical applications include commissioning new installations, troubleshooting communication faults, monitoring system performance, and validating protocol compliance. The ability to capture data across multiple segments simultaneously is particularly useful in large machines or plants where network complexity can make it difficult to identify bottlenecks or errors.

In summary, the Beckhoff ET2000 Industrial Ethernet Multi-Channel Probe is a powerful diagnostic tool that combines multi-channel monitoring, high-speed uplink, nanosecond timestamp accuracy, and passive operation in one compact device. It provides engineers with the insight needed to optimise, troubleshoot, and validate Ethernet-based industrial communication, making it an essential component of modern automation system maintenance and commissioning.
