Siemens SIMATIC MV500 Operating Manual page 16

Start page
Automatic disconnection on inactivity
Note that a timer runs in the background of the start page. After 5 minutes of inactivity, the
connection to the reader is automatically terminated. This ensures that the connection to the
reader is not blocked by an inactive user and is shared with other users.
A few seconds before automatic disconnection, a dialog window appears informing the user
of the upcoming disconnection.
This function is only active on the start page and is automatically reset by operator input.
