Tag integration allows you to directly integrate tags from a third-party control application or device into your IWS project.

Tag integration is an enhanced framework for device communication. It is built on the same communication drivers that are described in the Drivers section, but instead of manually configuring driver worksheets to associate project tags with device registers, you can use the Object Finder to browse the device registers and add them directly to your project.

Registers added in this way appear as tags in the Shared Database folder. They are “live” — that is, they are continuously and bilaterally updated during run time as long as the source is also running and properly connected — and they can be used anywhere in your project that you would normally use project tags.

These tags count against your target system’s tag limit only when you use them in your project. This is different from the driver worksheets, where you might create a group of tags in order to associate them with device registers but then never actually use them in your project.

Tag integration is configured in the Communication tab of the project settings.

This feature is supported only for certain third-party control applications and devices, because additional work is required to upgrade an existing communication driver for tag integration. However, many of the communication drivers included with InduSoft Web Studio can be upgraded, so if you do not see the one you want, then please contact your software vendor and ask about custom development.
