Abstract
Zur gegenseitig unbeeinflussten und unabhängigen Übertragung mehrerer Informationsströme über ein gemeinsames Übertragungsmedium wird das gesamte verfügbare Frequenzband des Übertragungsmediums in mindestens zwei Teilbänder (FB1, FB2) unterteilt. Das erste Teilband (FB1) weist eine untere Grenzfrequenz (fu) von mindestens 1 kHz, vorzugsweise 100 kHz auf. Das zweite Teilband (FB2) weist eine obere Grenzfrequenz (fo) auf, welche so gewählt ist, dass sich die Teilbänder sicher nicht überlappen. Im ersten Teilband (FB1) findet eine Informationsübertragung beliebiger Art und im zweiten Teilband (FB2) eine Informationsübertragung mit Mitteln der digitalen Übertragungstechnik statt. Im zweiten Teilband (FB2) können sicherheitsrelevante und im ersten Teilband (FB1) beliebige Informationen einer Sicherheitsanlage übertragen werden. For mutually uninfluenced and independent transmission of multiple information streams over a common transmission medium, the entire available frequency band of the transmission medium is divided into at least two subbands (FB1, FB2). The first subband (FB1) has a lower cutoff frequency (f u ) of at least 1 kHz, preferably 100 kHz. The second subband (FB2) has an upper limit frequency (f o ), which is selected so that the subbands certainly do not overlap. In the first subband (FB1) there is an information transmission of any kind and in the second subband (FB2) an information transmission by means of digital transmission technology takes place. In the second subband (FB2), safety-relevant and in the first subband (FB1) any information of a safety system can be transmitted.
