Interfaces
4.1 CNC operator panel (PCU) interfaces
4.1.5

PROFIBUS DP interface

The CNC operator panel (PCU) communicates with the I/O modules via the PROFIBUS DP
interface.
The PROFIBUS DP protocol is used for the communication.
The baud rate of the PROFIBUS DP interface is 12 Mbit/s; the baud rate cannot be chan-
ged. Converters for optical fiber cable (OLMs, OLPs) or repeaters are not permitted.
The operator panel CNC provides master functionality.

The CNC operator panel has a fixed PROFIBUS DP address.
The addresses of the PP 72/48 I/O modules must be set using the DIL switches S1
(see Section 7.12).
