Profibus Communication Rate and Bandwidth


The update rate of the Profibus communications is set in the Profibus master controller.  The GSD file of the drive allows a minimum time of 2ms.

The Profibus master will send the complete telegram every cycle: 4 words (parameter channel) plus 6 words (process data channel).  It does not necessarily change the data every cycle.  So, the cycle includes 10 words Output and 10 words Input, totaling 160 bits per transmission cycle.
