Abstract

A receiving logic of a network subscriber can be configured in a first filter setting to forward telegrams having first and second addressing techniques to first and second processing units, with a transmitting logic configured to forward the telegrams to a transmitting port. In a second filter setting, the receiving logic can be configured to duplicate the telegrams and forward to the first and second processing units, with the first processing unit configured to discard telegrams using the second addressing technique and the second processing unit configured to discard telegrams using the first addressing technique. The receiving logic of a third filter setting can be configured to duplicate telegrams and forward to the first and second processing units, with the transmitting logic configured to forward only telegrams using the first addressing technique from the first processing unit, and only telegrams using the second addressing technique from the second processing unit.
