This page provides information and downloads related to TIA Portal sample projects for Profinet communication between the Siemens S7 PLC's and AKD Profinet drive.
The sample projects use a function block to handle the telegram data and state machine (Control Word and Status Word). Another function block is used for the Parameter Access channel (PNU channel) to read and write values to drive parameters via the PNU numbers. Another function block is used to simplify the process of editing the position value of motion tasks. This is handled via PNU read/write. It could be done using the PNU function block, but that would require multiple steps and complicated ladder logic programming.
