Hello viren;

The Siemens Product Support pages very often provide help with configurations used wuith Siemens products.

Try it: use the Search box at the right of this page with search terms such as the one I did: "TIA Portal v12 G120 Profinet". You would have found many Application Examples or FAQs that could help you out, such as this one:

TIA Portal V12 Library with screens for Controlling a SINAMICS G120 Drive with a SIMATIC S7-1200/1500/300/400 Controller

https://support.industry.siemens.com/cs/ww/en/view/63042779

Study the available documentation and use the function block proposed as a basis for your own projrct.

Hope this helps,

Hello friend,

first assign the ip and station name.

configure the g120 drive via starter, it is easy to set up in few steps by using wizard.

send and receive telegram configuration should match in both nodes.

hello again,

Initially try standard telegram 2/2.

first word - control word.

second word - rpm set point (16384=maximum rpm).

send the command 47E to drive always via control word (off command).

otherwise you will get bus fault only.

47F for ON command. 

Thank you guys

I appreciate your help

Best regards

Viren
