Abstract
The invention relates to a method of connecting a mobile, electronic control and/or monitoring unit (9) to at least one machine or at least one machine component in a group or a plurality of machines (2) or machine components to be controlled and/or monitored. During a connection or log-on procedure between the control and/or monitoring unit (9) and a co-operating distant point on the respective machine (2), a clear link or log-on connection is set up either by means of interfaces (14, 15) to the selected, wireless direction-finder of the co-operating distant point or alternatively by means of transmitters and/or receivers (16, 17) tuned to a restricted, localized functional or operating range (21). Once the connection has been acknowledged and established, the programmed control and/or monitoring of the machine (2) or the machine component is managed via another, standard data transmission means (22), for example a hard-wired network and/or via a wireless link between the control and/or monitoring unit (9) and the selected machine (2). Also proposed is a control and/or monitoring unit (9) for implementing this method.
