National Instruments Labview Data Sockets ReadOnly

This document has only the specific information about the device connection settings and its address syntax.

Refer to the User Guide for more information on the Device Module.

This driver allows only to READ the channels, not write. The reason to have a read-only hardcoded driver to run on critical processes where the project should not be allowed to have a writing configuration option.
