> Please link current documentation. v8.0 is dead, dead, dead. [https://docs.inductiveautomation.com/display/DOC81/system.opcua.callMethod](https://docs.inductiveautomation.com/display/DOC81/system.opcua.callMethod) You cannot call this function from the designer script console. It is available in gateway scope only. (And Perspective, which is an extension of gateway scope.) (Use a gateway message handler to call the function. In the designer, use system.util.sendRequest() to invoke it.)
