The PX53 is a Mini PCI Express® PROFIBUS DP Master or Slave and PROFIBUS MPI card, which is also equipped with a cable connector fieldbus to connect the PROFIBUS assembly interface.
It features an advanced PROFIBUS controller which allows data transmission rates of up to 12 Mbit/s. The physical interface is isolated from the system.
The same hardware can be used either as PROFIBUS DP Master or PROFIBUS DP Slave and a change of functionality/protocol can easily be done by loadable firmware.
The complete protocol stack will be executed on the PX53 and data exchange to the host will be done via Dual-Port-Memory or DMA.
The PX53 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 PX53 to host and from host to PX53.
The PX53 supports a wide range of operating systems including Windows®, Windows® CE, Linux and VxWorks®.
The PX53 has been designed for mission-critical industrial and for mobile applications with demand for high resistance regarding temperature, shock and vibration.
