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:

Description |
Significant Features |
| FPGA (Field Programmable Gate Array) + Software Stack |
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.
