Star structure via DIN rail connector and RS-485 interface

Figure 1-8

Star structure, RS-485

The devices are connected via the DIN rail connector (T-BUS) in the head station.

The DIN rail connector supports RS-485. It can not be used with RS-232 and RS-422.

In order to configure a star structure, you must create several line structures.

In the example, you need to create two line structures, each consisting of three devices.

Figure 1-9

Example for a star structure (RS-485 interface on all devices)

In principle, a star structure via the DIN rail connector can only be used in combination

with the RS-485 interface.

Make sure that

all devices connected via the DIN rail connector (T-BUS) use the

same serial data rates
