Dear Sir In Siemens plc if we have profibus device such as an abb inverter connected to plc s7 300 , we can use PIW and PQW to read and write inverter reference and actuals. Also we can use DPRD_DAT and DPWR_DAT to control the inverter. Which way is better for control the profibus slave and what is the advantages of each other. I was wondering if you mention that.

Thanks for useful tips and tricks in TIA Selection Tool! I have just one question, how do I know which of ET200 compatible with for example S7-1200. I mean, if I want to have S7-1200 as a master and ET200 as a slave?
I have viewed most of all videos from your channel. Thanks for your great effort. I expect more and more videos. Also I have some suggestions for siemens to improve their software. How can I convay this message to them. I expect they need to add some more features with TIA portal to cop up more effecient application.
