Tria-Link 10kHz Real-time Bus

Präzision vs. Geschwindigkeit
  • 10kHz real-time fieldbus
  • Non-invasive inspection with a second PC

The data transmission of up to 32 participants in a 10 kHz cycle enables the transmission of motion data of coupled axes with the full quality of path planning. In addition, the Tria-Link synchronizes the clocks of the participants extremely precisely (<<100 ns), thus minimizing jitter.

All participant data can be queried in real time and at 100kHz clock rate via the Tria-Link and stored, processed or displayed on a host.

The Tria-Link is designed as a counter-rotating double ring, similar to the token ring. This enables it to achieve a transfer rate of 200Mbps, twice that of 100Mbps Ethernet. All bus participants can exchange data directly with each other - there is no actual bus master. The PCI adapter cards merely take on the additional task of starting up and cleaning up the ring, i.e. removing lost data packets.

Observer - Non-invasive Inspection

The Observer functionality allows non-invasive intervention in a running system. All system states can be observed in real time with up to 100kHz and recorded with the TAM System Explorer. Of course, parameters, e.g. control values, can also be changed during operation.

Typical applications are systems where real-time environments such as Beckhoff TwinCAT are used. In principle, these systems also allow data logging, but not with the convenience and sampling rate of the TAM System Explorer.

Another example is the integration of complex online measuring systems that run on their own PCs but must be supplied with real-time measurement data synchronously.
