open62541 is free & open source
You can download it from GitHub. There is no SDK or run-time license fee.
If it’s free, why do I need a partner?
OPC UA SDK FOR EMBEDDED TARGETS
We focus on helping customers right from the smallest of smallest sensors to customers who need an integrated TSN switch and embedded device profile.
Kalycito OPC UA Client Server SDK for embedded targets is based on open62541 – an open source implementation of OPC UA specification.
We have certifiable ports of open62541 available on different hardware and different operating system combinations. We also engage in quick prototyping and proof of concept projects. If you are interested in the embedded foot print numbers, performance numbers or certification of the solutions, you can book a meeting by clicking on the following link.

Commercial support for open62541
We provide commercial support for customers using open source OPC UA stack – open62541. We help you learn OPC UA technology and integrate into your products – including porting open62541 stack to your embedded architecture and certifying the product for compliance from OPC foundation. We also provide annual maintenance packages and priority support for critical bug-fixes.
open62541 is a free and open source software maintained by a community of developers and users. The certified release v1.0 was prepared by Fraunhofer IOSB and Kalycito Infotech with funding from an industry consortium via the Open Source Automation Development Lab (OSADL) eG. More details of this project can be found here.
The certified feature set of open62541 v1.0 is in conformance with the ‘Micro Embedded Device Server’ Profile of OPC Foundation supporting OPC UA client/server communication, subscriptions, method calls and security (encryption) with the security policies ‘Basic128Rsa15’, ‘Basic256′ and Basic256Sha256’ and the facets ‘method server’ and ‘node management’. open62541 also implements OPC UA publisher/subscriber communication.
OPC UA & Time Sensitive Networking
Today, the biggest challenge companies face when exploring new business opportunities is interoperability and solving this challenge will unlock the potential of Industry 4.0. We are thought leaders in this space. The new initiative by the OPC Foundation – OPC UA FLC promises vendor independent and end-to-end connectivity from sensor to cloud. We build on top of this major global initiative.
We are pioneers in building the open source eco-system for OPC UA including TSN. We started early and released PubSub in open source immediately after OPC Foundation released the part 14 specification. Even companies who hold proprietary IP in one part of what we do, leverage our work on other parts of the ecosystem to address their customer use cases. Our goal is to be a single eco-system for all the work involved in the Industry 4.0 end point device and edge device platforms, that includes optimizing the OS for real-time performance, time synchronization, functional and configuration parts of OPC UA, TSN and security. The following architecture diagram shows the different components that are part of an Industry 4.0 edge/end-point device.
