Hello.

I have problems communicating with any S7-1200 PLC through TIA V11. The problem began when i forgot to assign the IP ADDRESS to my computer, when i tried searching for the devices it showed me the PLC with the following address (which i assigned) 192.168.0.180, then i tried to communicate with the PLC and the TIA V11 gave me the option of auto assigning the IP ADDRESS to my computer, i clicked YES, since then i wasn't able to communicate with any PLC at all. I tried assigning the IP ADDRESS manually again but that doesn't work anymore. Hope anyone can help me.

I attached i file showing what i did and how my computer is reacting now.

PS. Sorry if my english is a bit weird or if it is lacking, i'll try my best. English is not my native language.

Thanks

Which is exactly the version of TIA? And type of OS? Is that a new installation of TIA or you used successfully before?

Hello,

it seems to be an problem with Siemens Protocol driver and the driver of you network card.
A yellow exclamation mark in PG/PC interface panel isn't ok. That will be also the reason why the checkbox will be removed.

Try to reinstall the driver for your network card. Maybe you will find a newer driveron Internet. This reinstallation will case a rebinding of all Siemens Protocol drivers to the network interface. Maybe this will solve the exclamation mark.

Other thing: Did you try the steps with DISABLED Wireless card (disabled in windows device manager, not only the wireless switch of your laptop). You are using two network adapters.If you don't use IP Addresses fromDIFFERENT IP Subnets on the cards, thenwindows will get some troublein separating telegrams. Microsoft suggests two different subnets.
