Abstract: A method for calling an industrial controller control program function block having an OPC UA server and using the OPC UA communication protocol to communicate with an OPC UA client, the function block requested from an OPC UA call of the OPC UA client. The method further comprising: a call step directed to the method of the OPC UA server sent from the OPC UA client to the OPC UA server; a stored step, the OPC UA call is stored by the industrial controller OPC UA server; a transfer step, IN Parameters are transferred together with the OPC UA call from the OPC UA client to the OPC UA server, and copied to corresponding control program function block IN parameters; and a called step, the control program function block is called at a previously defined point within a industrial controller control task, and the function block IN parameters are processed.

Abstract: A method for sequence control of program modules, includes providing a control means and a description file having a configuration for controlling a program sequence. The method further includes providing a plurality of program modules which can be executed by a real-time operating system, the program modules being created using one or different programming languages. The method furthermore includes initiating selected program modules by executing specifications in the description file using the control means.
