Updating
Loadables
Overview
Here are two possible scenarios that would require you to update a loadable:
Periodically, new versions of loadables are made available. If you try to delete an
old loadable from the configuration, the configurator alerts you to the fact that it
is already used in logic and prevents the loadables’ deletion. As adding or
readding a loadable can be an extensive task, update loadable conveniently
allows you to replace a loadable without first deleting it from logic.
You may have read a controller’s data into a project where the controller data
contained an .MSL loadable (i.e. an .EXE file from Schneider Electric or a third
party vendor). If the controller had been run prior to performing the read, the MSL
loadable in the project is unusable if written back to the controller. Use update
loadable to get the MSL loadable back to a state where it can be written to the
controller. Update loadable asks you for the original .EXE loadable. It places it
into the project and the project may then be rewritten successfully to the
controller.

Loadables
To update a loadable in a project:
Copying a
Loadable to a
Controller
To copy a loadable to a controller or project:
Step Action
1 Select Update from the right-click menu on the row of the loadable that you want
to update.
Step Action
1 Select the loadable’s checkbox. The Select Opcode dialog appears if no
Opcode has been set for the loadable.
2 Select an available Opcode from the list and click OK.
3 If you are offline, selected (checked) loadables are included in the project. Any
new loadables you check off will be added to the project when the configuration
changes are saved. To use the loadables in a controller, write to the controller.
See Writing to a Controller, p. 92 for more information.
4 If you are in online mode, changes are not made to the current project. If you add
loadables and close the configurator while online, the Configurator makes the
changes directly to the controller. (Note: The controller must be stopped.)
5 If you are in online combined mode any changes that you save are saved to the
current project and then written to the controller. (Note: The controller must be
stopped.)
