Hey, thanks for the very useful content! My question isn't directly related to this video, but I'm hoping you can help me. I'm using WinCC 8.0 Update 5 on Windows Server 2022 and working with the web client. Everything works fine initially, but after some time (a few hours), the clients are unable to connect anymore-they get stuck at 'connecting to server.' On the status page, I noticed that some floating licenses are used multiple times, even though the web client isn’t started multiple times on the PC. The only way to resolve the issue is to stop the runtime, close the project, and restart the IIS server. Unfortunately, Siemens support hasn't been able to assist us. Have you encountered this issue before, and do you have any tips or tricks to fix it? Thanks a lot!

[@WinCCGURU]

I haven't encountered exactly that issue. Are you using Web Navigator, or WebUX? I assume Web Nav. It is suspicious that the floating licenses are used multiple time, I am wondering if the clients are being disconnected and grabbing another license? I have seen issues where a client is run multiple times on the same PC and it causes a big load on the server and sometimes has to be reset. Check the siemens logs and Windows event logs to see if anything funny is going on with Windows or IIS. Also, any issues with the network acting funny, maybe dropping and reconnecting? Have IT look at that as well. I hope it helps!

@@WinCCGURU thanks for the quick feedback. It looks like the IIS service was corrupted, so I reinstalled it from scratch on a new virtual machine, and since then, I haven't encountered this issue again. I discovered something I wasn’t aware of: even if the IIS service isn’t running, clients web navigation (not the UX) that are already connected don’t have any issues communicating with the runtime server. I concluded that the IIS service is only used to initiate/negotiate the connection to the server. Is that correct? Siemens doesn’t really detail what’s behind this, so it would be great if you could create a special tutorial to present the connection and communication mechanisms between the web navigation and the runtime server in greater details.

[@WinCCGURU]

@@LoanVr Glad you got it working! I will have to investigate that, thanks for letting me know. cheers!!

Hello ,have you ever used wincc as opc as AE client? Im not able to view alarm data in wincc from third party system.Alarm appear in opc test client software, but not in wincc.OPC DA works wel in wincc

[@WinCCGURU]

I haven’t actually set up an AE OPC client to WinCC but you should be able to receive the alarm data via AE client. Did you check that the alarm messages are checked for storage in the database? There may also be some other settings you have to check in order to make it available to that client. I’ll take a look when I get a chance.

Hey, I was struggling with a gray screen in one of my clients screen, just remove the dash and boom, thank you a lot for the information Siemens should include the dash under the restricted characters for computer name

[@WinCCGURU]

Yeah that is a giant pain that isn’t documented. Glad it helped!!

[@automationtekto5823]

For network configuration, especially with multiple Ethernet cards, it may be a good idea to update the HOST file on each workstation.

[@WinCCGURU]

Agreed!

Hello Bob. Off-topic, but I need your help. I am logging some tags in Wincc7.5 but in the online table, older values suddenly vanished by themself. Now I can only see the values for past 1 week or so. I believe it may be because the archive size is too small. How can I increase its size? (Or is there a way to recover the values I lost/ make them reappear in the tables and trends)

[@WinCCGURU]

Its probably your archive settings. Go into tag logging editor, right click on "Archives" and select tag logging fast, properties. by default the archive size is 1 week and it backs up daily. change these as desired, then go back to tag logging slow and set it the same. If you haven't set this up before, the older data is probably sitting in your archive management folder of the project. you can reconnect older archives by going into runtime, then performing the steps above in tag logging, but select "link archive" instead of properties. doing this will make the older data available to trend and table controls.

[@WinCCGURU]

... note to self: make a video about archive management!

How to open the alarm page and it will automatic display alarm history on the screen without click anything ?

[@WinCCGURU]

Set the alarm control to default to alarm long term archive. It’s a property of the alarm control

In my project ,there are many internal tags, these tags are used in reports. If i unselected the tag in report designer, then the sql query window will get active,other wise tag window in report designer is active.My question here is these tags will be used anywhere in global script in the project or to store the sql query output?

[@WinCCGURU]

See the new “reporting” video in the Udemy database course which covers this. If you select tag for query window then the object will expect to find a sql query in the tag versus what you put in the query window.

[@syamlyanatomy]

Second question is there are many internal tags available in project, is there a way to find out which script or report its used?( I searched in cross reference,can't find the linking with script and report), few of these internal tags are used in report designer as wel

[@syamlyanatomy]

If required I could share the back up to you, so that you wil get .ore idea on what I'm talking,you could add those concept in future videos also

[@WinCCGURU]

In WinCC V8 The cross reference editor will find tags used in Report Layouts. I was able to find the _Begin_Time_ tag from my report layout used in DB Course and it found it.

[@syamlyanatomy]

@@WinCCGURU great, 7.5 doesn't have that, Will it fetch tags from global script?Since most of the tags won't be available as exact text in scripts
