The ProfibusDP RepeaterHDP-200 should be used in the following situations
If More than 32 connected nodes in the bus.
If the segments can’t be connected in any manner at a given shield or common ground.
If the maximum cable length estimated by the baud rate of the configuration, has been reached by the RS-485standard.
In the Figure1,a typical application of theHDP-200is illustrated.

Due to the characteristic impedance of RS-485 transceivers to be around 12K,care must be taken to use a maximum of32 nodes per network segment, to notcompromising the communication channel.

Therefore, to increase the scale of the network repeaters should be used.In some circumstances, ground loops are present in the bus segments and must be canceled, thus as the HDP-200repeater has 2 isolated communication channels, it is possible to solve many problems of the physical layer.

When the cable length limit by the communication speed is reached, the HDP-200 repeater assists in the configuration of fastand big networks, with amplifying and regenerating the data signal.
