Information model for human-machine (tool) interaction

Abstract For the development of OPC UA servers for machine tools the complex architecture of numeric controls and programmable logic controllers is often depicted in a structure focused on data. The information models provide access to a wide set of available data points but lack intuitive functions, such as handling of NC programs and controlling auxiliary systems, which would be used by machine operators in manual mode. The information model presented in this paper shows a possible solution to combine data and functionality of machine tools in an intuitive structure in order to simplify navigation for clients and users.
