Stopping or starting the Gateway

The →Gateway is automatically started when logi.CAD 3 is started and it is automatically stopped when logi.CAD 3 is exited.

If you want to stop/start the Gateway from within logi.CAD 3, perform the following steps:

  1. In the Instances view, expand the item PLC Information for the PLC which is addressed by means of a Gateway.
    Note:

    • If there is an established connected to the PLC and the Gateway is running, the state Online is displayed.

    • If there is no connection to the PLC or the Gateway is stopped, the state Offline is displayed. In this case, best practice is to check also the displayed text for Details on connection why a possible connection attempt via Gateway has failed.

  2. In menu PLC, select Stop Gateway or Start Gateway. (The current state of the Gateway determines which one of the commands is being provided.)
    Result: If variables are visible in the Values of Variables view, the values are not updated anymore (if the Gateway has been stopped) or they are displayed/updated again as after loading the application (if the Gateway has been started).


If the Gateway has already been started outside of logi.CAD 3, the following behavior applies:

  • The Gateway is not started when logi.CAD 3 is started and it is not stopped when logi.CAD 3 is exited.

  • It is not possible to stop/start the Gateway from within logi.CAD 3. Hence, the command Stop Gateway resp. Start Gateway is disabled.
