A Proven Integration Roadmap for Success

Real Time Automation provides flexible integration packages to support PROFINET IO Device source code stack integration from design to deployment. The process described below is subject to change based on your unique needs. Included services vary by package.
- Pick Your IO Device Integration Package: Choose the integration package that matches your engineering environment:
- Standard: A “do-it-yourself” package ideal for manufacturers who understand PROFINET and can handle their own stack integration
- Guided: An RTA-assisted package that includes hands-on support, data model design (GSDML) and PI pre-conformance testing. Ideal for manufacturers with limited PROFINET experience or engineering resources.
- Turnkey: An end-to-end integration service where RTA’s Enginerds handle the entire raw Ethernet/UDP setup, data modeling, stack integration and lab representation. Ideal for manufacturers who are new to PROFINET and do not have in-house engineering resources.
- Make It Official: Lock in your project with a purchase order and signed license agreement to officially start your PROFINET integration project
- Meet Your Enginerds: RTA assigns you a dedicated Enginerd to discuss your device and integration goals
- Model Your Device: RTA does the heavy lifting and takes the data available from your device and properly models it to the PROFINET object structure, providing all data models, documentation and communication files
- Pre-Conformance Testing: Your device is tested in the RTA lab to ensure it meets the highest standards for data integrity and industrial security. For protocols that require certification, like PROFINET, RTA also runs certification testing and provides the test results you need to present to the conformance lab.
- Device Conformance: You schedule your test date with PROFIBUS & PROFINET International (PI) and RTA’s Enginerds represent your device at the lab
- Go to Market: RTA trains your support and sales team to help them effectively sell and support your product’s new communication features. RTA can also review your technical and sales documentation to support your go-to-market efforts.
- Rest Assured: RTA is a member of PROFIBUS & PROFINET International and is aware of upcoming changes to the PROFINET specification before it formally takes effect. This ensures that if you need to update your device or enable PROFINET on new devices, you are getting source code conformant to the latest standard.
