Trendserver does not receive trends (data)
Hello together I have a question aubout the Trendserver as you can see in the Titel of the question. I have adjust everything that i know but it wont work. I can see the Trendserver and its online.
The Trendserver has the Res.ID 239
I configurte the OPC Tunnel (Tunnel Port: 9950 HTTP Port: 9960 DA Server: Freelance2000OPCServer.239 AE Server is empty)
The Gateway configuration has the Port Nr: 9950
In the paraeter of the Profibus Slave Modul PROFI_S_MOD OPC-Acces is given.
is there any other adjustment i have to do?

The Trend server is a standard OPC DA server with RO access - it has no visualization or archivization capabilities on its own. Its sole purpose is to allow usage of Trend Displays without Trend Acqusition block and Operator-defined Trend displays.
If You would like to have a copy of trend archives on Trend Server station you have to use File Transfer option of Trend display as discribed in Documentation (I attach an extract on this topic).

The settings You've shown look all right. Are You sure that the it's the Trend Server that does not recive data?
My suggestions on what other things You might want to check:
1) Restart System Tray - You should do it after any changes done with OPC Tunnel;
2) Check time synchonization - if Your PS is not in sync You won't see Your Trends correctly;
3) Change data shown in the trends - sometimes trends won't update unless the input data changes;
I also attached a short document on OPC tunnel configuration.
I hope it will help.
