Set ESP Variable VI

Owning Palette: Output VIs

Requires: Full Development System (Real-Time, Windows)

Sets variables to be visible in an ESP scripting template. You can access these variables from the form variables in the ESP template. Refer to the Scripting in LabVIEW Web Services topic at ni.com for more information about using scripting with Web services. The data type you wire to the value input determines the polymorphic instance to use.

Note  For more information about concepts in this topic, refer to the Web services introduction and tutorial.

Set String ESP Variable

	LabVIEW Web Service Request is an identifier used by Web Services VIs to reference a specific HTTP request. LabVIEW Web Service Request works similarly to a refnum in LabVIEW, allowing you to wire together Web Services VIs within your application. You must wire Web Services VIs to the LabVIEW Web Service Request control or an existing value from the LabVIEW Web Service Request out terminal of another VI. When you use Web Services VI(s) within a Web method VI, you must assign the original LabVIEW Web Service Request control to the connector pane of the Web method VI.
	key sets the name of the ESP variable.
	value specifies the string value to assign to the new ESP variable.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	LabVIEW Web Service Request out is an identifier that VIs on the Web Services palette use to reference a specific HTTP request. Use LabVIEW Web Service Request out to wire together Web Services VIs within your application.
	error out contains error information. This output provides standard error out functionality.
