The PX51 is a Mini PCI Express® DeviceNet master or slave card, which is also equipped with a cable connector fieldbus to connect the DeviceNet assembly interface.

It features a DeviceNet interface supporting an ISO high-speed of up to 500 kBit/s. The physical interface is isolated from the system.

Master or Slave protocol configuration can easily be done by loadable firmware. The complete protocol stack is executed on the PX51, and data exchange to the host is done via Dual-Port-Memory or DMA.

The PX51 is based on the netX SOC. This highly integrated network controller supports parallel data transmission via several data paths between the internal CPU and graphics engines, and the communication and host controllers. The netX SOC also controls the on-board memory and other peripheral interfaces such as UARTS, USB, SPI or I²C.

Communication works via a dual-port SRAM interface and is supported by window and pointer access mechanism. Interrupts are available in both directions from PX51 to host and from host to PX51.

The PX51 supports a wide range of operating systems including Windows®, Windows® CE, Linux and VxWorks®.

The PX51 has been designed for mission-critical industrial and for mobile applications with demand for high resistance regarding temperature, shock and vibration.
