5.4 Interrupting and restoring a connection
Introduction
The connection to the server can be interrupted in several ways:
• The server is offline or has not completed its startup sequence.
• The password is incorrect.
• A firewall is blocking server access.
• The server has been shut down, for example, for maintenance purposes.
• The PROFINET/Ethernet network cable has been disconnected.
• A connection problem occurred in the network.
• A client-server connection was started on another device which logs onto the server with
the same data. The client-server connection running on your device is then terminated.
Note that there can be multiple client-server connections at one time.
Automatic connection establishment
The device offers the possibility to re-establish an interrupted physical connection
automatically. There are two basic standard cases for this:
• Initial start of a connection
The connection cannot be established because the server is not ready, for example. The
device makes continuous attempts to establish the connection to the server.
• Existing connection
An existing connection to the server is interrupted because the network cable has been
removed or the network is faulty, for example. The device attempts to re-establish the
connection to the server.
You can find additional information in the section "Connection settings (Page 97)".
