Abstract

A method for calling a function block of a control program of an industrial controller is disclosed. The industrial controller has an OPC UA server and communicates with an OPC UA client, wherein the function block is requested from an OPC UA call of the OPC UA client. When the function block is requested, an OPC UA call directed thereto is sent from the OPC UA client to the OPC UA server. The OPC UA call is stored by the OPC UA server. IN Parameters transferred together with the OPC UA call are then copied to corresponding IN parameters of the function block and, the function block is called at a previously defined point within a control task of the industrial controller and the IN parameters of the function block are processed.
