High-speed fieldbus connection for host PC
The Tria-Link PCI Express® Adapter TL establishes the Tria-Link connection between the Triamec Servo Drives and a PC.
On the host PC side, the adapters are programmed with the TAM API under Windows or Beckhoff TwinCAT.
This card requires a short, half-height, PCI Express x1 slot with a data width of x1 according to the PCIe-2.1 standard. All common PCs meet this requirement.
TL has 8 real-time tables with a total of 2 096 000 entries. This allows, for example, pre-calculated, multi-axis paths to be stored and then executed. A further feature is that the path target data can be continuously reloaded. The tables are designed as FIFOs, so the paths can be of any length.
They are equipped with a Tria-Link Observer, which is accessed via USB. A notebook can be connected via the USB port for diagnostic purposes like commissioning, axis tuning and recording of process data. The application on the PC (e.g. TwinCAT) is not disturbed.

|---|---|
| DMA | DMA support greatly minimizes CPU load on the PC containing the card, e.g. when logging or scoping over the Tria-Link. When using Beckhoff TwinCAT, TL can communicate the actual position to the CNC at 1–2 kHz in real-time. |
| PC Interface | PCI Express® v2.1, Lane Width 1x with 2.5 Gb/s according to PCIe-1.0 standard. |
| Fieldbus-Communication |
Tria-Link, Fieldbus, based on a double 100 Mbps Ethernet link.
Multi-Master feature allows for direct drive to drive communcation. |
| USB Interface / Observer | USB 2.0 High-Speed Device Interface with 480 Mb/s. The Observer Interface allows the non-invasive connection of a Windows-Notebook with TAM-Explorer to the Tria-Link Network. The operator can do all tasks of commissiong, axes tuning and full speed, real time data logging (100 kHz). |
| Power | Delivered through the PC Interface, 2.5 W max. |
| Software | Triamec TAM API for Microsoft® .NET Framework; Beckhoff TwinCAT mit CNC |
| Memory | 128 MB |
| Direct Feed | 64 MB FIFO buffer for >2 096 000 set values = 20 seconds for 10 axes at 10 kHz |
| Dimensions | w×h×d 22×80×113 mm |
