System 10 Labview Driver

This new communications driver gives users of National Instruments' LabVIEW software fast and flexible access to analog and digital data acquired by any System 10 instrument or network, while maintaining the intuitive "look and feel" of current LabVIEW functions and features.

Using LabVIEW's versatile graphics-based "G" programming language, the System 10/ LabVIEW interface can run on any platform that supports LabVIEW- including Windows, Windows NT, and Power Macintosh.

The driver software provides the LabVIEW user with a comprehensive "Interface Library" of preprogrammed "Sub VI" ("Sub Virtual Instrument") modules. By incorporating these modules into your own application design, you can achieve real-time System 10/LabVIEW data exchanges that are fast, reliable, and easy to implement.

High interface rates result from the use of special System 10 binary mode commands. These commands compact individual data transmissions and thus reduce the workload of the communications channel. Extensive error handling routines ensure the highest data integrity over the interface.

There are standardized Sub VI's for

setting up and closing down serial or GPIB communications functions

reading requested data from System 10 for a single channel and/or logic bit, or for an entire array of channels and/or logic bits (channel "reads" can include limit status and scaling information, if desired)

writing a boolean value to a specified System 10 logic bit (perhaps for purposes of triggering the automatic execution of a sequence of control commands)

writing a single-precision value to a specified System 10 data channel

sending to System 10 any valid "read" or "write" command for immediate execution.

The Interface Library also includes a number of useful sample applications- including examples of data gathering and display, datalogging, terminal interfacing, and channel configuration and calibration.
