Initializes an HTTP connection for SystemLink data services to communicate with your SystemLink Server using your SystemLink Server login credentials and a CA certificate for authentication.
A Boolean that determines whether this VI will verify the connection is secured by a valid certificate. The default value is True.
URL of the server where this node sends the web request.
URL Syntax
Part | Definition | Example |
---|---|---|
Scheme | Protocol the web service uses. | http:// |
Host | Domain name or IP address of the service. | localhost |
Port | HTTP port of the web service. If you don't specify a port, the web service uses the default port. | 80 |
Use the following syntax to prompt a connection to the SystemLink Server: https://host:<port>.
Use the following syntax to prompt a connection to the SystemLink Cloud server: https://api.systemlinkcloud.com.
To host a web application on a SystemLink Server, leave the server url input empty.
Default: http://localhost:80
Login username for the server.
Login password for the server.
File path to where a custom or private CA certificate ( .cer) is located on the system.The CA certificate authenticates a secure sockets layer to communicate data between your application and the server. If you leave this input unwired, the VI uses the system defaults, which includes public CA certificates.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Connection to the server.
Error information.
The node produces this output according to standard error behavior.

When you host your web application on SystemLink Server, leave the server url, username, and password inputs of the Open Configuration (User) node empty. To minimize security vulnerabilities, SystemLink Server will use your LDAP or Windows user account credentials for authentication.
Where This Node Can Run:
Desktop OS: Windows
FPGA: Not supported
Web Server: Supported in VIs that run in a web application
