Hi,

I have a Asus laptop, I5 / 8GO DDR3 / W7 Ultimate x64 ans a PLC Siemens S7-1200.

I reset my PC and install STEP7 V5.5 - My PLC is find with "Device accessible" with PN/IO interface

I Install TIA V13 - My PC not found my PLC with "Device accessible" and STEP7 V5.5 does not work anymore.

I reset My PC install TIA V13... plc not found - I install TIA V14... plc not found.... Why ?

It's work only with virtual machine... but it's. What is the solution without virtual machine ?

Thanks

Welcome.

Do you have some firewall?

Please reinstall latest PC ident version.

Best regards.

Hello,

Have you tried to use a static IP address?, sometimes it causes the problem when you allow your pc to get an automatic IP ad.

See the attached File

Hope it Helps

I had the same problem once, but in combination with Microwin (S7-200).

I installed TIA, wich worked, After that i installed microwin and Tia couldn't find any devices since then.

Installing newer network driver helped, so maybe you should try that.

hi,

have you installed the Siemens SW with admin-rights and with deactivated anti-virus-scan?

how did you deinstallate the SW?

you can try a repairintallation with full admin-rigths(rigth-clickon setup.exe->run as admin) an with deactivated anti-virus-scan.

regards,

Hello all,

pls look, in my opinion all depends to Win OS updates, also if you have enabled via your manufacturer notebook drivers update. Simply be careful what your PC will install/update. This is bigest problem.
