DAQmx Write TEDS Data (VI)

Owning Palette: DAQmx TEDS VIs and Function
Installed With: NI-DAQmx

Writes TEDS data to the TEDS sensor connected to the physical channel you specify. This VI can write TEDS data from a 1D array of 8-bit unsigned integers or from a virtual TEDS file.

U8 Array

Writes data from a 1D array of 8-bit unsigned integers to the TEDS sensor.

physical channel is the name of the physical channel you want to configure. A DAQmx physical channel constant or control lists all physical channels on devices and modules installed in the system. You also can wire a string that contains a physical channel name to this input.

TEDS bitstream is the TEDS bitstream to write to the sensor. This bitstream must be constructed according to the IEEE 1451.4 specification.

National Instruments provides a LabVIEW library for viewing and editing TEDS bitstreams and virtual TEDS files. You can download the TEDS Library for LabVIEW at ni.com/pnp.

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

cbool.gif

status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.

ci32.gif

code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.

cstr.gif

source identifies where an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.

ci32.gif

basic TEDS data options specifies how to handle basic TEDS data in the bitstream.

Do Not Write (12540)

Ignore basic TEDS data.

Write To EEPROM (12538)

Write basic TEDS data to the EEPROM, even if the sensor includes a PROM. You cannot write basic TEDS data if the PROM contains data.

Write To PROM Once (12539)

Write basic TEDS data to the PROM. Any subsequent attempts to write basic TEDS data result in an error.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

ibool.gif

status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.

ii32.gif

code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.

istr.gif

source identifies where and why an error occurred. The source string includes the name of the VI that produced the error, what inputs are in error, and how to eliminate the error.

Virtual TEDS File

Writes data from a virtual TEDS file to the TEDS sensor.

physical channel is the name of the physical channel you want to configure. A DAQmx physical channel constant or control lists all physical channels on devices and modules installed in the system. You also can wire a string that contains a physical channel name to this input.

virtual TEDS file specifies the filename of a virtual TEDS file that contains the bitstream to write.
