PLCSIM Advanced - How to fix the NPF Error (NetGroup Packet Filter Driver)

in this video i'd like to show you one error message that could appear if you're working with fields limit once for the first time or you're setting up a virtual plc over your network adapter for the first time here i've already opened the field sim advanced user interface so if i now set the switch to right to appeal to the virtual ethernet adapter this message here appears and it says that the netgroup package filter driver npf is not running on this system and this usually appears if you are working with an older version of psim at once like in my example with the version 3.0 if you are working with version 4.0 or newer then the npf driver should be installed with the standard plcm advanced installation and for those who still receive that error message i will show you how you can fix that so if you type in cmd and open the command prompt you should run that as an administrator and in there you can check if the driver is somehow already installed and for that you just type in net space start net npf and if you receive the message that the server service name is invalid it means that the npf driver is not installed for you so to fix that you need to install the driver manually so you have to open the website win winpcap.org install slash default dot htm and in here you find the installation file for windpicap and usually you will find the latest version here so you click the download link and after the download is finished which should happen really fast because it's a really small installation file you simply double click on that installation file and run through the installation process by simply clicking on next next and install and after that when the installation is finished you can type in that command in cmd again and we receive the message that that service has been started so that's the result you want to see if that system is running and now if i set the switch to plc virtual ether adapter you see that it's possible and now i'm able to create a virtual plc which runs over my network adapter that's it for this video if you have any questions leave a comment and i'll try to help you as good as i can and if you want to learn more about all features and functions of plcm advanced and how you can use the plc advanced api to create your own simulation and testing tool you should check out the links in the description box
