Configuring a Controller

‘Loadables’ TabOverview User loadables are instructions that do not come with a c ontrol ler. In stead, they are
supplied by Modicon or third-party vendors and must be copied into a controller or
project to be used.
Loadables are extensions to a controller’s capabilities. When they appear as logic
function blocks (most of the time) they are represented as three node instructions.
The Loadables tab displays the loadables selected and availab le to be selected for
the current project.
The display shows a table of loadables and related information. A check mark is
shown beside loadables that are present in the project. Loadables with no check
mark are present in the loadable library, but are not currently availabl e in the project.
To add or delete a loadable from a project, select or de-select the associated
checkbox.

changes.
