One of the primary benefits of adopting a free OPC client is that it reduces the cost of developing and testing industrial automation systems. This is especially beneficial for small and medium-sized businesses, freelance developers, and academics without a huge budget for automation tools.
Free OPC clients can also be beneficial for studying the OPC standard and learning how to communicate with industrial equipment. They can serve as a solid foundation for designing customized automation solutions or connecting with current systems.
Another key element of free OPC clients is that they can be quickly adapted to a project’s particular requirements. Because they are open source, developers can access and modify the source code as necessary.

Before opting to use a free OPC client, it is essential to assess a project’s requirements thoroughly.
In conclusion, free OPC clients provide a cost-effective solution for connecting to OPC servers and communicating with industrial hardware devices. However, they may have some restrictions in comparison to commercial alternatives. Before making a selection, it is usually essential to examine the compatibility with the OPC Server at your facility and to research and try various options.
