Principle of operation
To be able to control 3RW55 or 3RW55 Failsafe soft starters via the web server on the "Control
Panel" web page, you must be logged in (Page 98) with a user account ("Operator personnel"
or "Maintenance personnel" user role) via a secure https connection. For more information on
user account management, refer to the 3RW55 and 3RW55 Failsafe Soft Starters Equipment
Manual. All other functions (monitoring, diagnosis) are possible without logging in.
If you control the 3RW5 soft starter via the web server, the 3RW5 soft starter is in the operating
mode "Manual operation bus - Webserver controlled" (Page 24).
Connection abort
The connection between the web server and web client is monitored. If the web server has
control, the 3RW55 or 3RW55 Failsafe soft starter reports a connection abort if the connection
is interrupted for at least 10 seconds and stops the motor if it is switched on. The Web client
connection is terminated automatically and the Web server is no longer in control. Connection
aborts are, for example, an interrupted cable connection or closing the web browser.
