About session expiration

FactoryTalk ViewPoint

uses session expiration to automatically release client connections in case a user has unexpectedly disconnected or is away for an extended period.

A session expires when:

When a session expires, the web browser displays "Session has expired". To reconnect to the

FactoryTalk ViewPoint

server, the user must refresh the web page and sign in again.

Status Pings and Session Timeout

By default, the

FactoryTalk ViewPoint

client sends a status ping to the web server once every 10 seconds. If the web server does not receive the status ping within the client connection timeout period, the session is ended. The client connection timeout period is 30 seconds.

Common causes of client connection timeouts are network failure, unexpected power loss, or an application crash.

Inactivity Timeout

By default, the

FactoryTalk ViewPoint

server has an inactivity timeout of 20 minutes. If a user does not change or refresh a display within the inactivity timeout, the session expires.

Specify the inactivity timeout settings on the

Server Settings

page.
