Overview

The Synchronize Changes command lets you apply to the control project changes that you make to properties of an M580 PAC in the Topology Manager and the vice versa, in a single step, while Control Expert Editor is open.

When you use the command, changes to the control project are saved.

Change Indicator

An asterisk is displayed next to the name of the PAC in the SYSTEM PROJECT pane to indicate that a modification to its properties in the Topology Manager has not been applied to the control project and/or a change to its configuration in Control Expert Editor has not been applied to the system project.

The asterisk appears only when Control Expert Editor is open and a modification is made after opening it. Also, it appears only for the user who has made the modification.

The change that you make in the Topology Manager needs to have an impact on the control project. Changing the Under Construction attribute, for example, does not display the change indicator.

When the asterisk is displayed and Control Expert Editor is open, the Synchronize Changes command is available.

NOTE: The asterisk appears also when you make a change in Control Expert Editor to data that is not managed in the Topology Manager (for example, changes in the Programs directory).

Working Principle

The table outlines the process that is performed when you select the Synchronize Changes command and changes have been made in both the system project and the control project.

Step

Description

1

The PAC is analyzed. If incorrect configurations are detected, no changes are applied to either project.

2

Changes to the configuration of the control project are applied to the properties of the PAC in the system project.

3

Changes to the properties of the PAC are applied to the control project.

4

The control project is saved.

5

When the process is completed, the Synchronize Changes command is disabled. Control Expert Editor remains open.

Synchronizing Changes in Virtual Connected Mode

You cannot use the Synchronize Changes command while virtual connected mode is enabled for the control project.

Synchronizing Changes After Deploying

Once you have deployed the executable to a PAC, using the Synchronize Changes command requires that you stop the controller to deploy any modification. Some exceptions apply.

Canceling the Synchronize Changes Command

If after selecting the Synchronize Changes command, you close Control Expert Editor and select to discard changes before the save operation can complete, the synchronization of changes is canceled both ways.

Undoing the Synchronization of Changes

Using the Undo command in the Topology Manager immediately after synchronizing changes discards the changes that you have made in the control project and those that have been applied by the synchronization. Open the HISTORY pane to verify which action is undone.
