Hi. I have s7-1500(v2.0) and inverter g120c(v4.7.6). They are connected ascros switch. When I test inverter in starter it's no problem with connection and start/stop. I have that error. Name profinet i/o divice it's the same found when I add inveter to project. PLC ip is 196.168.6.80 and inverter 196.168.6.74. PC 196.168.6.16.

Hello,

which switch you are used?
Do you have a port interconnection in the Topology in the offline project?

Hello,

and have you a port interconnection in the project topology?
If yes then delete this interconnection!

edit:

ok you have a port interconnection, so the ports must be in real connected like in the project.
Remove the XB Switch, or delete the Port Interconnection between the devices in the project!

if you create a new project have you assign a new name to the G120?
In the first screens it was waga40 now is drive_1?
