6.2
PROFIBUS interface terminal assignment
PROFIBUS interface
The table below shows the terminal assignment of the PROFIBUS interface. The assignment
corresponds to the standard assignment of RS485 interface.
Table 6- 2
Note
No 24 V DC supply voltage
The PROFIBUS interface does not provide a 24 V DC power supply. I/O devices (for example,
PC adapter 6ES7972-0CB20-0XA0) are therefore not operational on the interface.
