The basic characteristics of transformation technology:
 Net topology: Linear bus, there are bus resistor in two ends.
 Transforming speed: 9.6k bit/s
–12M bit/s
 Medium: double-shielded twisted pair cables, the shield can be removed according to the
environment (EMC).
 Station number: There are 32 stations in each segment (without relays) as to 127 stations (with
relays)
 Contact pin: 9 frames D pin, the connector contact pins are as below:
Contact pin of the connector Instruction
1 - Unused
2 - Unused
3 B-Line Positive data (twisted pair cables 1)
4 RTS Sending requirement
5 GND_BUS Isolation ground
6 +5V BUS Isolated 5V DC power supply
7 - Unused
8 A-Line Negative data (twisted pair cables 2)
9 - Unused
Housing SHLD PROFIBUS shielded cable
+5V and GND_BUS are used in the fieldbus terminals. Some devices, such as light transceiver
(RS485) may get external power supply from these pins.
RTS is used in some devices to determine the sending direction. Only A-Line wires, B-Line wires and
shield are used in the normal application.
It is recommended to apply the standard DB9 connector of SIEMENS. If the communication baud rate
is above 187.5kbps, please follow the connection rules of SIEMENS seriously.
