7.8 PROFIBUS DP
7.8.1 Application
Connectable devices
The following devices can be connected to the PROFIBUS DP interfaces:
● Distributed I/O
● Drive units with PROFIBUS DP interface (standard slaves)
● S7 controllers with PROFIBUS DP interface
● PG/PC
Note
Isochronous operation with PROFIBUS DP for the NCU is only possible at the line of
terminal X126. Only signals from the PLC I/Os can be evaluated on the line of terminal
X136.
Properties
● Isolated RS 485 interface
● Max. data rate 12 Mbaud
● Supports master/slave operation
● PROFIBUS address is set via configuration
Note
In addition to the DP (distributed I/O) protocol, X136 can also transmit the MPI (multi
point interface) protocol (software-controlled).
