Does anybody know how to put the gateway connection protection on your own scripting? I want my code to respect the communication protection settings on designer:

You would retrieve that connection mode from the live [GatewayConnection](https://files.inductiveautomation.com/sdk/javadoc/ignition81/8.1.1/com/inductiveautomation/ignition/client/gateway_interface/GatewayConnection.html#getConnectionMode()), which you get from the [GatewayConnectionManager](https://files.inductiveautomation.com/sdk/javadoc/ignition81/8.1.1/com/inductiveautomation/ignition/client/gateway_interface/GatewayConnectionManager.html#getInstance()) singleton. You would enforce your restriction in your Client RPC implementation, prior to invoking the RPC call. (I don’t think you can do this on the gateway side–it is purely a designer UI element.)

Oh! I meant blocking in the designer, like System.DB.runPrepUpdate does on it.

Yes, it is that connection property. You replied without even taking a moment to read the links. Tsk.
