Activating a deactivated module

All incorrectly configured modules in a model will deactivate if the model is run. The deactivation is indicated by a break through the center of the module's icon (see Module graphical elements). You can reactivate a module by configuring it correctly.

Modules deactivate most commonly for the following reasons:

Mandatory parameters are not configured
Input layer missing
Output file not specified
More than one layer fed into a thin port

Caution: If you connect a module with a single output layer to a second module, a thin pipe will connect the modules. If you then increase the number of output layers, a fat pipe will connect the modules. However, the thin input port will not change to a fat input port. If you run the model, the second module deactivates.

On the canvas, click a deactivated module, and then right-click.
Choose Open MCP(s). The module's control panel opens.
Click the Log tab, and read the error message.
Click the tab containing the incorrect configuration, and provide the correct input parameter or parameters.
Click Accept.
Note: If a module deactivates because an incorrect layer was loaded in the Import module, you do not have to reactivate the module prior to the next run. Simply load the correct layer and re-run the model. The module will automatically reactivate.

Note: Choosing the Clear All Caches command from the Edit menu also activates deactivated modules. However, you must still view the module's control panel to determine the cause of the deactivation and to properly configure the module prior to the next run.
