XNET Database Create (Dynamic Signal).vi

XNET Database Create (Dynamic Signal).vi

Purpose

Creates a new XNET dynamic signal.

Format

Inputs

	subframe in is the subframe parent object.
	signal name is the name of the signal to create. The name must be unique for all signals in a frame in which the subframe parent was defined, including the static signals and the multiplexer signal. Lowercase letters (a–z), uppercase letters (A–Z), numbers, and the underscore (_) are valid characters for the name. The space ( ), period (.), and other special characters are not supported within the name. The name must begin with a letter (uppercase or lowercase) or underscore, and not a number. The name is limited to 128 characters.
	error in is the error cluster input (refer to Error Handling).

Outputs

	subframe out is a copy of the subframe in parameter. You can use this parameter to wire the VI to subsequent VIs.
	signal out is I/O name of the newly created signal object.
	error out is the error cluster output (refer to Error Handling).

Description

This VI creates an XNET dynamic signal object. It is an instance of the XNET Database Create Object poly VI.

The signal name input becomes the Name (Short) property of the created object. This is distinct from the string contained within signal out, which uses the syntax described in XNET Signal I/O Name.

The signal object is created and remains in memory until the database is closed. This VI does not change the open database file on disk. To save the newly created object to the file, use the XNET Database Save VI.

Dynamic Signal is transmitted in the frame when the multiplexer signal contains the multiplexer value defined in the subframe.

In NI-CAN, dynamic signals were called mode-dependent channels.
