Configuring a Controller
372 SPU 780 01EMAN May 2002 83
‘Loadables’ Tab
Overview User loadables are instructions that do not come with a controller. Instead, 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 available 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 available in the project.
To add or delete a loadable from a project, select or de-select the associated
checkbox.

a loadable is a two-step process: transferring it into a loadable library (see the
Loadable Library Wizard, p. 86), then selecting it from the library into the controller
or project by checking the loadables’ checkbox in the loadables tab and saving
changes.
Parameter Description
Name User loadable name.
Opcode A unique two-digit hexadecimal number used to identify an instruction in the
programmable controller logic.
Version The version number of the installed loadable.
