Why we believe in open source

We believe that community driven open source software can alone offer true interoperability. Such an Eco-system also helps reduce R&D costs for organizations significantly.

Organizations can now focus on their core differentiators instead of spending on base technologies like OS, communication and security which are no longer a key differentiating factor in their product or service offering. Thus the cost of development for these shall be community driven.

As you can see Open Source should be part of your core business strategy and should not be a distant second option for consideration or seen as an alternative to proprietary technologies. You may still need proprietary components to differentiate your product or service.

Help us help you

The open source OPC UA community project (open62541) aims to develop an open source OPC UA library equipped with Publish and subscribe features and real time capabilities. This community project was initiated and maintained by a joint working group including Fraunhofer IOSB in Karlsruhe, Germany, the India based system integrator Kalycito Infotech and the Open Source Automation Development Lab (OSADL)
