More Information
Summary:After connecting a device to the switching device through device-specific connect command and transmission of a start command as well as transmission back of a start command acknowledgement signal, the connect command is partially or slightly changed and transmitted again, whereupon the switching device transmits a stop command to the particular device. The stop command is responded to by the particular device with a stop command acknowledgement signal transmitted back only, if after established connection it has received a start command before a stop command. The activation error is recognized in that after output of the changed connect command and the stop command transmitted thereupon each time, a stop command acknowledgement signal arrives in the switching device.
