I am using SFB52 and SFB53 to do the acyclic reading of drive parameters. I found an example on how to do this and it works fine, but what I am looking for is a description of the data records that can be used. The example uses data record 47 and gives the structure for the data blocks, but I want the reasoning behind this. Is there anywhere where I can get a definition of all the data records? Any help please

This Profidrive profile isspecified (standardised) by PI (Profibus & Profinet International, the User organisation that governs and develops Profibus and Profinet). I hope this explains itbut more can be found at www.profibus.com
