2.1ET2000 Introduction
Fig. 1: ET2000
Industrial Ethernet multi channel probe
With the ET2000 multi channel probe Beckhoff introduces a versatile piece of hardware for analyzing any Industrial Ethernet solution. With eight ports this device enables unlimited synchronized recording of up to four independent channels at a speed of 100 Mbit/s. All realtime Ethernet standards such as EtherCAT, PROFINET, etc. and conventional office Ethernet networks are supported.
Through its compact and rugged design the ET2000 is ideal both for the local application at machines or in the laboratory. The four channels enable recording and analysis of separate networks or different points within the same network. All frames in transit – in both directions – are furnished with a highprecision timestamp in the probe hardware and copied to the Gbit uplink port.
The high timestamp resolution of 1 ns enables very precise timing analysis of the connected network segments. The ET2000 probe is transparent for the connected buses. Thanks to the low cycle delay of < 1 μs the influence on the system is very small. The device can be connected to any Gbit Ethernet interfaces on the PC side.
It is supplied with a Windows driver based on the open WinPcap software interface. This means that the versatile ET2000 probe can be used with freely available network monitors such as Wireshark (Ethereal).
