EtherNet/IP Adapter Source Code Stack
Ship EtherNet/IP-enabled devices in weeks, not months, with RTA’s royalty-free EtherNet/IP Adapter source code stack. Trusted in over 100,000 real-world applications, our EtherNet/IP Adapter source code has been enabling devices like PLCs, VFDs, barcode readers, I/O blocks and more for over two decades.
Optional add-ons for Device Level Ring (DLR) and CIP Security Confidentiality Profile allow you to meet complex network topologies and modern cybersecurity requirements without modifying your core device firmware.
EtherNet/IP Adapter Source Code Stack
Accelerate Your Time to Market with RTA’s EtherNet/IP Adapter Stack
Don’t let complex protocol development delay your product launch. RTA’s royalty-free EtherNet/IP Adapter source code stack is designed to get your devices to market quickly.
You simply map your device data to the EtherNet/IP object structure (object/instance/attribute), and the RTA stack handles all the heavy lifting, including packet encoding, decoding, transport and required interfaces.
- 35+ Years of Industry Leadership: Built by the team that developed the very first ODVA-certified EtherNet/IP device and backed by over 35 years of industrial networking expertise
- 100% Royalty-Free Licensing: Ship an unlimited number of devices with a single upfront purchase and no ongoing royalties or hidden fees
- Market-Tested ANSI C Source Code: EtherNet/IP source code written in-house by RTA experts and proven across hundreds of device types and over 100,000 real-world applications
- Simplified TCP/IP Socket Integration: Easily map device data directly to the EtherNet/IP object structure to keep integration simple and fast
- Lightweight Footprint: Fits easily into memory-constrained processors, making it ideal for bare-metal microcontrollers or any RTOS
- Direct RTA Enginerd Support: Work directly with the Enginerds who wrote the code for hands-on guidance on data modeling, stack integration and pre-conformance testing

A Proven Integration Roadmap for Success

Real Time Automation provides flexible integration packages to support your EtherNet/IP Adapter 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 EtherNet/IP Integration Package: Choose the integration package that matches your engineering environment:
- Standard: A “do-it-yourself” package ideal for manufacturers who understand EtherNet/IP and can handle their own stack integration
- Guided: An RTA-assisted package that includes hands-on support, data model design (EDS) and ODVA pre-conformance testing. Ideal for manufacturers with limited EtherNet/IP experience or engineering resources.
- Turnkey: An end-to-end integration service where RTA’s Enginerds handle the entire TCP/IP setup, data modeling, stack integration and lab representation. Ideal for manufacturers who are new to EtherNet/IP 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 EtherNet/IP 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 EtherNet/IP object structure, and provides all data models, documentation and communication files
- Stack Integration: Integrate EtherNet/IP source code into your device, either with your in-house team or assistance from RTA (varies by package)
- 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 EtherNet/IP, RTA also runs certification testing and provides the test results you need to present to the conformance lab.
- ODVA Conformance: You schedule your test date with ODVA 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 sits on several ODVA Special Interest Groups (SIG) and is aware of upcoming changes to the EtherNet/IP specification before they formally take effect. This ensures that if you need to update your device or enable EtherNet/IP on new devices, you are getting source code conformant to the latest standard.
