We believe in making the details of how a product licensed as transparent as possible to help you understand what you receive for your investment in a product and relationship with Software Toolbox.
The OPC Data Client is a development toolkit intended for use in creating custom applications. The product is most commonly used by users and systems integrators building custom applications for a specific use in customer facilities. For the most common applications, you can distribute compiled applications without any additional cost, details are below. We offer a variety of license types that can be purchased for any of the product editions shown on the ordering page. All OPC Data Client licenses are perpetual licenses.
This is the most commonly purchased license type and can be ordered from our ordering page.
This license is an add-on to the Single Developer + Runtime Free license that must be owned by the same company. Purchase allows an additional developer to work with the software concurrently with other licensed developers within your company.
Additional developer licenses cost less than your initial license, please contact us for a quote.
Any number of developers at a single physical location of the same company can develop software and you can deploy compiled applications to any number of computers on any site, free of any further royalty payments.
If you have a multi-site development need, please contact us so that we can work out an appropriate multiple site license.
Contact us for any pricing needs involving site licenses.
You may transfer licenses between computers used by the licensed developer, or to a new developer within your company, provided you are on an active support and maintenance agreement.
You may not have more than one developer per license owned using the product at the same time. Additional developer licenses are available at discounted prices, as are site licenses. Contact us for details.
We reserve the right to limit transfers if circumstances suggest there is an attempt to circumvent the per developer seat licensing.
You can upgrade between editions of the OPC Data Client - such as from Professional to Enterprise, for as little cost as paying the price difference, provided that you are on an active support and maintenance agreement.
If you are not on an active support and maintenance agreement, you can still upgrade, but the cost to upgrade will include reinstatement of your support agreement.
The product documentation provides details on how to deploy your runtime free license on target machines automatically, using your own installation program or how to embed the required license details into your application.
You will receive a license file with your purchase, which you will then install on the development machine using the included License Manager Utility. Using that same utility you can transfer your license to a different development computer.
OPC Data Client licenses are perpetual licenses. That means you own the license forever, as opposed to a subscription license where you have to pay an annual fee to keep using it.
You do need to have an active Support & Maintenance Agreement in order to have access to phone and email support and product updates.
Since you are developing an application that your user expects you to keep current with Windows OS updates and OPC specification updates, we highly recommend, but do not mandate, that you keep your Support & Maintenance Agreement active.
We do not offer hardware keys or dongles as a license delivery method.
The demo is the full product. Once the OPC Data Client is connected to an OPC Server, it will run for 30 minutes at a time. The 30–minute timer will be disabled after 210 days from the initial version release.
