Transformation by double-shielded twisted pair copper cable is the most common way in
PROFIBUS/CANOPEN (conform to RS-485standard).
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:,
12345
9 8 7 6

PROFIBUS/CANOPEN shielded cable
+5V and GND_BUS are used in the fieldbus terminals. Some devices, such as light
transceiver (RS485) may get external power supply form 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.
