Hello everyone,
I have a problem with SIMATIC NET V8.2 SP1 and STEP 7 V5.5 Sp4 (STEP 7 Prof. 2010 SR4) on OS W7Pro SP1.
I have formatted the HD three times, starting from zero, and reinstalled everything (STEP7 and then Simatic Net), but the problem still coming back.
The first time it all works, but after restarting the PC the OPC server does not work anymore and I find certificates OPC UA in error.
On the website of Siemens products compatibility seems ok, also from Siemens Support Hot Line no answer ...
A colleague solved by installing STEP 7 V5.5 Sp1.
Does anyone have/had the same problem? How to fix it?
Thanks
