WCF Service Error (HttpWebRequest_WebException_RemoteServer)

[Savan Tripathi]

Dear Mikhail,

Currently I am trying to map data of modbus device with schema by taking existing server schema and made duplicate schema and save as new name. I have put input channel value in schema editor and save in and put schema in view.

Now i am login to scada account and clicking on schema it is showing me WCF service error. I had googled it and also go through your forum and try to made changes as per described in forum but still facing the same problem.

I dont know how to install a latest WCF version. i had checked IIS manager Configuration and all services are currently activated.

please give me some suggestion regarding it.

What is your Windows version?
Please open http://localhost/scada/scheme/ScadaSchemeSvc.svc and post a screenshot.

I am using windows 2008 server

By putting your URL in browser there is blank page with the error ::::

Application error: The HttpsGetEnabled property of ServiceMetadataBehavior is set to true and the HttpsGetUrl property is a relative address, but there is no https base address. Either supply an https base address or set HttpsGetUrl to an absolute address.

Try the following:
0. Make a backup of C:\SCADA\ScadaWeb\Web.config
1. Open C:\SCADA\ScadaWeb\Web.config
2. Find the line
3. Delete httpsGetEnabled=”true”
The line should be

Open http://localhost/scada/scheme/ScadaSchemeSvc.svc again.
