When choosing the format by which PROFINET will be integrated into a device, it is mainly dependent upon the eventual goals and applications of the component. Different solutions exist for this; broadly they are:
The FPGA is based on the chosen operating system, then it is supplemented by a supplier supported PROFINET stack.
Flexibility
Easy Updates
Additional Hardware Switch Needed
Standard Microcontroller (MCU)
Add PROFINET to an existing MCU for “Ethernet on a chip” and deploy your own PROFINET stack.
Cost Effectiveness
Single Port Software Switch is Possible
Certified Boards & Modules
This is hardware that is supplied by PROFINET embedded vendors for integration into devices.
Short Development Cycles
Easier Certification
Low Risk
ASIC (Application Specific Integrated Circuit)
ASICs are chips with full functionality built into and designed specifically for PROFINET usage.
High Performance
Integrated Hardware Switches
Certified Conformance
Second Source Support
External Coupler
An external coupler has the PROFINET interface implemented which is then connected in series.
Low Development Costs
Short Time to Market
Many of these products are supported with SDKs (software development kits). With each option, there are multiple choices for consultation and engineering support, through vendors themselves and through the global PI Competence Center network.
