Industrial communication
Connection of controllers to PROFIBUS –
Communications processors
Make your controller fit and ready for connection to PROFIBUS
• Use PROFIBUS for the networking of distributed
devices, peer-to-peer communication,
and programming the controller CPU
• An independent communication processor
ensures the continuous sampling of the
distributed devices – separate from the
sampling by the controller
• A number of communications processors
can be used for segmenting the distributed
devices
• Plug-in module for easy connection to the
backplane bus of the controller
• Support of redundant I/O in connection with redundant controller
