open62541 Github
open62541 an open source implementation of Open Platform Communications Unified Architecture (OPC UA), is licensed under the Mozilla Public License v2.0. Based on the IEC standard IEC 62541, open62541 is available royalty-free on GitHub under the open-source license (Mozilla Public License v2.0). You can download the stack here.
open62541 SDK
Kalycito helps leading Machine-builders and automation OEMs globally with consulting and integration services. On identifying the potential behind the open62541 stack, PubSub, and TSN as candidates to become a universal communication standard from the field level to the cloud, Kalycito triggered the initial move and funded the initial development of PubSub parts under an Open Source license suitable for industry and to build an ecosystem around it.
Between 2018 and 2022, we have been the second highest contributor to the open-source stack. Additionally, during the period, we also delivered industrial projects using open62541 for Automation Component vendors looking at using OPC UA in their embedded devices. Kalycito has helped in integrating OEM/Machine-builders having OPC Unified Architecture (OPC UA) integrated into their existing machines. To help companies learn and do it on their own, we also have a course .
open62541 Features
Portable
- Written in C99 with architecture-specific plugins
- Runs on Windows, Linux, VxWorks, QNX, Android, and diverse embedded systems

Certified
- Sample Server (server_ctt) certified against the ‘Micro Embedded Device Server’ Profile
- Supporting OPC UA client-server communication, subscriptions, method calls, and security (encryption)
open62541 OPC UA server
The sample server (server_ctt) built using 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’.
PubSub (UADP) is implemented in open62541. However, the feature cannot be certified at this point in time (Sep-2019) due to the lack of official test cases and testing tools.
open62541 is 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.
open62541 is developed and maintained by a community of contributors from a wide range of backgrounds. The certification is the result of the joint work of all contributors to open62541. For the latest information on certification, visit www.open62541.org/certification/
