A laser system consists of the source itself and one or more additional components that are either optional (e.g., a pilot laser) or required (e.g. a cooling system, a laser source controller) to operate the source itself. The laser may be used for different tasks such as cutting, welding, sintering or melting. These laser systems are often integrated into a large CNC or PLC controlled machine, which may already be OPC UA capable or even part of a larger OPC UA environment. The primary goal of this first part of the specification is to also incorporate the laser systems into OPC UA environments. Consequently, creating a standardized interface for maintainers which offers information regarding for example the current state of the laser system or upcoming maintenance intervals.
