Client/Server Connection
Overview
Clients connect with the system server through an Ethernet cable connection, for example to:
• Access the database.
• Access software Participants.
• Launch tasks that are performed by the system server.
• Receive notifications from the system server.
• Verify digital certificates and license rights.
You cannot use clients while the connection to the system server is interrupted or while the system server is not running.
You can test the client/server connection (see EcoStruxure ™ Process Expert,
Installation and Configuration Guide).
Notifications About Client/Server Connection Interruption
The table describes the various notifications that appear client-side for different scenarios where a client cannot connect to the system server or the virtual machine anymore.

If the connection to the system server is still functional, save changes, close the Participant window, and start over once the problem is fixed.
If the connection to the system server is interrupted, refer to scenario 3.
If the reason for the connection interruption cannot be determined, you need to contact Schneider Electric

The following figure shows an example of the notification that appears for scenario
4 in case you are refining a Control project online.
After Re-establishing the Connection to the System Server
Clients automatically reconnect to the system server when the connection is reestablished or when the system server is running again. After reconnecting, clients display a notification to inform you of the communication interruption.
Unsaved changes are discarded and open windows are reloaded or closed automatically.

If the system server has stopped, the notification panel is empty when the system server restarts. To view the history of activity up to the interruption of the communication, open the
After an unexpected interruption of the client/server connection, the states of both the engineering client and the system server may have become inconsistent. This can be the case, for example, if at the time of the interruption an operation was in progress such as an import of several Participant projects or pasting of many instances.
NOTICE
LOSS OF COMMUNICATION
After an interruption of the client/server connection, verify that the last operation executed by the software was completed successfully, and if necessary, repeat the last operation.
Failure to follow these instructions can result in unresponsive clients.
You are able to resume using the software when the connection to the system server is re-established or when it is running again.
