Hi
I have some basic functions to perform with a Micromaster 420 (PPO3) via a Step 7 program.
I have configured Profibus DP in the HW Config, but after reading the manuals, the method of controlling the VFD in Step7 has still not sunk in.
I would really appreciate some advice or an example of the best practise on 'PZD data handling' in a program.
(Refer to ladder please as my understanding of STL is poor)
