OPC UA describes functionality that allows for programs to be executed as part of the OPC UA Server. These programs can be used to perform advanced control algorithms or other actions. The use of these actions should be restricted to personnel with appropriate access rights. Furthermore, the definition of Programs should be carefully monitored. It is recommended that statistics be maintained regarding the number of defined programs in addition to their execution frequency. This information is available to administrative personnel. In no case should an unlimited number of program executions be allowed.
