PROFINET Device (Slave) for Intel FPGA

Integration of PROFINET RT & IRT into Field Devices using Intel (Altera) FPGA

IP Core and software have been designed to implement a PROFINET communication based on hardware supporting an Ethernet interface and an Altera FPGA. This solution provides uniform interfaces for future support of additional Industrial Ethernet protocols.


Easy and Inexpensive Development of PROFINET Field Devices Using Altera FPGAs

  • Ready-to-integrate PROFINET Qsys system
  • Maximum flexibility to meet customer requirements
  • Future versions can easily be integrated

One API For Quick Integration

  • Simple Device Application Interface (SDAI) designed as efficient protocol abstraction layer to use different protocols with same application
  • PROFINET RT/IRT, EtherCAT, EtherNet/IP, POWERLINK and Modbus TCP using the same API
  • Single and dual processor systems supported

Improved Performance

  • Minimum I/O data delay between physical layer and application
  • Process data processed by DMA logic
  • Guide to efficient application programming included

Standard IT Support in Parallel with IndustrialEthernet

  • Direct forwarding of IT Packets to application
  • No need to change existing IT structure
  • Socket interface for simple integration
