Why Support & Maintenance Matters
When you embed the OPC Data Client into a custom application, that application's long-term reliability depends on the toolkit staying current with the OPC servers it communicates with, the Windows versions it runs on, and the .NET and compiler versions your development environment targets. Support & Maintenance is your assurance that compatibility is maintained as each of those components evolves.
All new OPC Data Client license purchases include 1 year of Support & Maintenance. Renewals are annual and can be co-termed with other Software Toolbox product licenses you hold.
Built for developers: Support staff have deep OPC Data Client development knowledge — not just general technical knowledge. When you raise a complex question about OPC UA security negotiation, DA subscription behavior, or XML-DA transport, you're talking to engineers who know the product's internals.
What Support & Maintenance Covers
An active agreement gives your development team access to updates, expert guidance, and priority support across all OPC Data Client editions.
Re-registration and transfer of your license to a new computer, or re-installation following hardware failure, is covered while on active support.
What Is Not Covered
To keep annual renewal costs low, certain services are outside the scope of the standard Support & Maintenance agreement. Our professional services team or system integrator partner network can address many of these needs on a paid basis.

A Note on Code Debugging & Third-Party OPC Servers
If a product defect is suspected, we ask that you reproduce the issue in the most minimal code test rig possible. We will use that reproduction in our work to determine whether a product issue exists — this keeps investigations focused and turnaround fast.
For issues involving a third-party OPC server (not purchased from Software Toolbox) that has been confirmed, via other OPC test clients, to be a problem in that server: we will gladly collaborate, but the owner of that OPC server license will need to engage that vendor's support directly. We can work alongside them to resolve the issue together.
Using a Software Toolbox OPC server? If the OPC server connected to your OPC Data Client application was also purchased from Software Toolbox (such as TOP Server or OmniServer), we support both products simultaneously under their respective active Support & Maintenance agreements — no hand-offs, no separate escalations.
