Fuente: Wipo "BigData" The present invention relates to a client device (1) and a system (100) for data acquisition and pre-processing of process-related mass data from at least one CNC machine (10) or an industrial robot and for transmitting said process- related data to at least one data recipient (10), e.g. a cloud- based server, the client device (1) comprising at least one first data communication interface (2) to at least one controller (11) of the CNC machine (10) or industrial robot, for continuously recording hard-realtime process-related data via at least one realtime data channel (7), and for recording non-realtime process -related data via at least one non- realtime data channel (8). The client device (1) further comprises at least one data processing unit (5) for data- mapping at least the recorded non-realtime data to the recorded hard-realtime data to aggregate a contextualized set of process -related data. Moreover, the client device (1) comprises at least one second data interface (3) for transmitting the contextualized set of process-related data to the data recipient (20) and for further data communication with the data recipient (20).
