There are four things that you should do every time you create a control module.
Identify the operator pictures that will be associated with the module.
Assign the module to a controller node.
Save the module to the database.
Verify the module's configuration.
The procedures for accomplishing these tasks follow. (An additional step is downloading. Modules can be downloaded to a controller individually. However, we will download our whole control strategy at one time, as you will see at the end of this chapter.)
You will see what operator pictures look like and how they are used. For now, you simply need to know how to associate the module with the pictures.
