10.2.1 General information about PROFIBUS
10.2.1.1 General information about PROFIBUS for SINAMICS
General information
PROFIBUS is an open international field bus standard for a wide range of production and
process automation applications.
The following standards ensure open, multi-vendor systems:
● International standard EN 50170
● International standard IEC 61158
PROFIBUS is optimized for high-speed, time-critical data communication at field level.
Note
PROFIBUS for drive technology is standardized and described in the following document:
Reference: /P5/ PROFIdrive Profile Drive Technology
CAUTION
Before synchronizing to the isochronous PROFIBUS, all of the pulses of the drive objects
must be inhibited - also for those drives that are not controlled via PROFIBUS.
The cyclic PZD channel is deactivated when the CBE20 is plugged in!
CAUTION
No CAN cables must be connected to interface X126. If CAN cables are connected, the
CU320 and other CAN bus nodes may be destroyed.
