EcoStruxure Web Services Server Setup

This screen is only available if an EcoStruxure Web Services Server has been configured in your project. Configuration of this feature requires Windows administrative privileges. If logged on as an administrator you will need to register with elevated privileges. In the Windows User Account Control prompt, click OK to proceed. If logged on as a non-administrator, you will be prompted to enter an admin password.

Note: Citect SCADA EWS services supports two types of authentication: Basic and Anonymous Each uses a different endpoint:
1) Basic authentication uses
https://<ewsServerAddress>:<ewsServerPort>/DataExchange
2) Anonymous authentication uses
https://<ewsServerAddress>:<ewsServerPort>/DataExchange/ReadOnly

Endpoints information is exposed by the online WSDL .

To service requests from web service clients use this setup dialog to reserve the URL of the EcoStruxure Web Service on the computer.

Click on the Register button. This will reserve the URL for all users on the computer. You need to register the URL once. If the URL is not registered, EcoStruxure Web Services Server will need to be run as administrator on the computer.

If the URL is successfully registered, the message "URL reservation successfully added" will be displayed. If the message "URL reservation add failed, Error: 183. Cannot create a file when that file already exists." is displayed, the URL has already been registered.

Note: This will register the EWS for all users. You can manually control access by using the Windows utility netsh.exe. Only users for whom the URL has been reserved will be able to start the web service. For more information refer to Modifying the URL Reservation.
