Restart the System Online

With the online restart facility, you can change your project configuration and examine the results in the runtime system without having to shut down Plant SCADA. You can update your system while it is running.

Note: If you’ve configured Plant SCADA to use multiprocessor support, it is recommended that you use the Runtime Manager instead of the restart facility. The runtime manager allows you to restart different processes individually, whereas the restart facility will restart every Plant SCADA processes on the machine.

The time taken for the system changeover depends on the size of the project and the extent of the changes to the project:

• If you only change graphics pages, Plant SCADA does a partial restart (changing only the pages in the runtime system). Changeover is instantaneous.

• If you change any databases (for example, add a new alarm tag, trend tag, or Cicode function), Plant SCADA does a full restart to run the updated project.
