Overview

Thanks to the client/server architecture of Control Expert, several users can work on the same component or different components of a system project at the same time.

For example, User A and User B can work in the Default Physical View of the same system project to design the architecture. Or, User A can add devices to the architecture of the system project while User B configures logical networks and communication properties of devices. These operations could also be performed by a single user.

In both multiuser and single user environments, the Topology Manager manages system-wide concurrent user access to views and configuration screens to preserve the integrity of data of the system project.

In case of conflict, the Topology Manager may allow access to data in read-only mode only or forbid certain actions. Dialog boxes open to inform you.

If desired, a user can lock a system project to restrict access by other users.

NOTE: Locking mechanisms may also operate when a single user is performing certain concurrent tasks.

Change Propagation

Changes made to data of a system project are reflected right away in other instances of the Topology Manager in which the same system project is open.

Concurrent User Activity Management

When the command that you have selected cannot be completed, you can obtain information about the reason through:

  • Dialog boxes that open when you try to access system data that is being used or edited by another user.

  • Information displayed in the Activities tab of the notification pane about activity of other users connected to the same system server.
