Variable Links

The various task input or output variables can be linked when selected either with the context menu or the dialogue shown on the right-hand side, e.g. with the I/O Configuration.

Context Menu

Some of the selection options in the context menu are only available when the configuration is active, and the system is running or they have other dependencies. If that is the case, they aren't high-lighted.
