You must set the TCP connection timeout according to how often the Guardian Sensors send out heartbeat messages (sensor health messages).
What you should know
The TCP connection timeout setting is how long the SDS Guardian plugin waits to receive a heartbeat message from a sensor. The sensor is considered offline if the plugin does not receive a heartbeat message from the sensor before the timeout ends.
- From the Config Tool home page, open the Plugins task.
- In the Plugins task, expand the SDS Guardian plugin role from the entity browser.
- Select a gateway, and then click the Connection tab.
In the Connection section, enter a value higher than the
heartbeat message frequency configured in Guardian Gateway.
NOTE: The default timeout is 20 seconds.
- Click Apply.
