Connectable devices
The following devices can be connected to the PROFIBUS DP interfaces:
●
PG/PC
● SIMATIC HMI devices
● SIMATIC controllers with PROFIBUS DP interface
● Distributed I/O
● Teleservice adapter
● Drive units with PROFIBUS DP interface (standard slaves)
Note
For
remote diagnosis, a teleservice adapter can be connected to the PROFIBUS X126 or
X136 interface. A teleservice adapter can only be connected to one of the two interfaces.
The power supply for the teleservice adapter (terminals 2 and 7) can accept current loads
as high as 150 mA and is sustained short-circuit proof.
