Good afternoon forum, 

This fees like a simple question so ill make it short, i have a g120c pn inverter that i would like to control with a s7-1200, is it possible to do this without using any fisical digital inputs?

for example i would like to change the speed, ON/OFF and inversion from the s7-1200, is this possible?

Hi,

yes this is possible.

You can control the G120C complete from the S7-1200 vie PROFINET.

 Cheers ChristophD im going to try it now and ill let you know how i get on,

Just one last thing tho the BF light keeps on flashing what does that mean?

 Thats probably why im getting all these errors lol,

Oke im going to check over all the ip`s to see if everything is oke

Thanks again!

Hi,

if BF LED is on it means BUS ERROR, Something is wrong with the connection between PLC and device.

This can be a defect cable or wrong adress settings, or NameOfStation is not correct or IP is not correct.
