We are in design phase. One of the requirements is that our PLC's (S7-1500) shall support IPV6.

Did anyone ever connect a S7-1500 PLC to WinCC OA via the S7 or the S7+ protocol ?

Thanks

I'm using several versions 3.19/3.20 and have noticed the following issue since last friday (although I installed nothing on my laptop). I'm using a developers license. I would assume that my problems are caused by some kind of Windows update and hope that you can give me a solution or osme ideas to...

I understand your statement. Our projects are all about traffic where we get integer 'State' data from barriers, doors, traffic lights, smoke detectors. Also some analog values from air quality, temperate and such. Normally the number of changes per second is relatively low. Doors don't open much, b...

WinCC OA is suitable for very large applications. I've seen distributed applications where each server (pair) was handling many 10 thousands of dp elements. But how much is 'ok' for a single server (pair). What is your experience ? What about: * 50.000 alarms * 100.000 alarms * 200.000 alarms Does a...

Install a tool like pgAdmin to directly look into your database. Note: I had to install a different version. The one that came with my PostgreSQl installation crashed. I then installed a different one, with a different version number, and this worked The databas scheme will show you that 2 views are...

when used in WinCC OA 3.19 P012.

Sorry. Missed your post.
Yes, we are running a big C# API manager on 3.19. I am not sure about the patch number but we do not have any issues. if you want, I could verify our patch number for you.

We have been using PostgreSQL in the redu-aware mode. This doesn't worj well because the pgClusterMonitor script is not working very well. We are now investigating the non-redu-aware setup (using two backends) We were hoping/wondering the purpose of the 'handleRedundancy' element. Can we change the ...

I'm investigating the NGA. The help file says that the dp element 'handleRedundancy' specifies "Database is capable of handling redundancy on its own (redundancy-aware database)." But what does this mean for the NGA manager (or its backend). What is the difference in the storage of data wh...
