Open Configuration (User) (G Dataflow)

Version:
    Last Modified: August 7, 2018

    Establishes a SystemLink Server connection using HTTP or HTTPS. The node authenticates the connection with a valid username and password.

    Programming Patterns

    server url

    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

    datatype_icon

    username

    Login username for the server.

    datatype_icon

    password

    Login password for the server.

    error in

    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.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    configuration

    Connection established with the server.

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Node Configuration for Hosting Your Web Application on SystemLink Server

    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
