    The radio modules 11, 21, 31 are all designed in such a way that an antennais integrated into those that act as transmitters and receivers ofradio signals. A radio signal can be transmitted between two or more ofthe devices in the automation plant 1, i.e. welding robot 10,tool 20 and logistics 30. With one or more radio signals, data cantransferred between the devices in the automation plant 1, i.e.the welding robot 10, the tool 20 and the logistics 30. This data can, for examplebe measurement data that the tool 20 sends to the welding robot 10. This data canfor example, also be measurement data that the tool 20 receives from the welding robot10. The tool 20 and / or the welding robot 10 can thus also be referred to asmeasuring devices. The tool 20 is in particular a battery-powered,handheld, measuring tool 20.
    In the automation plant is carried out according to the present exemplary embodimenta simple method for direct communication or for data exchange betweenthe devices in the automation plant 1, i.e. welding robot 10,the tool 20 and the logistics 30. The communication or data exchange takes place inreal time. Real time here means that the communication or data exchange takes place inaccording to the human perception during the actual time, i.e. inreal time. The time required by the radio modules 11,21, 31 to performthe communication or data exchange is not perceived as a delay.
    Radiomodu | erna11. 12, 31 work and / or react within a lotsmall specified time frame.
    In the method according to the present embodiment of the method, data is exchangedbetween the devices 10,20, 30 in the automation plant 1. In connectionwith this, for example, data is sent to the radio module 11 and thus tothe robot 11 from the tool 20 by means of the radio module 21 viathe communication link 41. The robot 10, more specifically itsradio module 11, receives the data sent from the tool 20. As beforementioned, the communication, ie the transmission and reception of, is performedSida5av11101520253035350261 DEdata, in connection with this in real time. This data can, for example, be requested bythe robot 10 in a control of the welding device 12.
    In a similar way, data can be exchanged between the radio modules 11, 31 andthus the robot 10 and the logistics 30 in real time via the communication connection40. In a similar manner, data can be exchanged between the radio modules 21, 31 andthus and real time viatool 20 logistics 30 icommunication link 42.According to the method described above, the communication or data exchange andhence the exchanged data available quickly. For this, a standard is usedreal-time capable protocol with small data packets, such as a compactfieldbus protocol. In this context, it is about a very simpleprotocol. l / led the rapid availability ensures that the devices inthe automation plant 1, i.e. the welding robot 10, the tool 20 andlogistics 30, is ready for use very quickly.
    In summary, a real-time data exchange takes place inthe automation system 1, which is preferably radio-based, for synchronizationbetween tools, in particular hand-held, possibly battery-powered, screw tools,screw spindles, riveting tools between the tools and between the abovesaid tools as well as between other devices inthe automation plant, for example the robot 10, the welding device 12,stationary screw systems and the like, possibly with connection ofthe infrastructure in the manner shown, for example, in Fig. 1.
    According to a second embodiment, the communication is used inthe automation system 1 for monitoring several devices 10, 20, 30,especially at the same time. In particular, the robot 10 and the tool 20 cancontrolled on the basis of the same data. Thanks to this canthe devices 10,20, 30, for example, are synchronized. In addition, several candevices 10, 20, 30 in the automation plant 1 are configuredat the same time. Incidentally, the automation plant is 1 according to thisembodiments performed in the same way as in the first embodiment.

Thereby, it can accordinglydesigned the device of the devices 10,20, 30 to act as a gateway,router and access point. Consequently, they can be equivalentthe devices not only send and receive data themselves but alsoforwarding data to other devices 10, 20, 30 iautomation plant 1.
    In this way, the scope of the network or the individual radio connectionsrange is increased in the present embodiment. The network that this leads tocan also be described as a mesh net.
    Incidentally, the automation plant 1 is according to this exemplary embodimentperformed in the same way as in the first embodiment.
    According to a fourth embodiment, the communication is used inthe automation system 1 for monitoring several devices 10, 20, 30,especially at the same time. In addition, there is the possibility of obtaining an error identificationby a redundant execution of the bidirectional communication exchangeor a data transfer between the devices 10,20, 30iautomation plant 1. Incidentally, the automation plant is 1according to this embodiment performed in the same way as in the firstthe working example.
    All the above-described embodiments of the automation plant 1 and itsdevices 10, 20, 30 and the method can be used separately or in allpossible combinations. In particular, all features and / or functions ofthe embodiments described above are optionally combined. In addition, inin particular the following modifications possible.
