Configuring Class II TEDS Tasks using the SC-2350 Carrier
PrintOverview
This document describes how to use hardware Transducer Electronic Data Sheet (TEDS) smart sensors with National Instruments signal conditioning Data Acquisition (DAQ) systems that are TEDS enabled. This document provides step-by-step instructions for the configuration process that allows you to see your sensor TEDS file and measure from the sensor in LabVIEW.

Configuring the SC-2350 Carrier & TEDS Sensors
1. Launch Measurement & Automation Explorer (MAX) by double-clicking the desktop icon.
2. Expand Devices and Interfaces using the + icon. Right-click NI-DAQmx Devices»Create New NI-DAQmx Devices»NI-DAQmx SCC Connector Block»SC-2350.
3. The SC-2350 Configuration window, shown in the following figure, opens. Keep the DAQ Device and the SCC Connector Block ID as the default.
4. Use the drop-down list to select the appropriate SCC TEDS module and the corresponding location, Jx.
5. The LED to the right of the module is bright green if the sensor is connected, as shown in the following figure.
6. Expand your SC-2350 by clicking the + icon, then expand the module connected to the TEDS sensor and click the TEDS icon, shown in the following figure, to highlight the TEDS sensor.
Creating a Global Channel or Task
2. Select NI-DAQmx Task or Global Channel and click Next. Select Analog Input and the appropriate measurement type for the sensor. For example, select Temperature»RTD for an RTD.
3. Click the TEDS tab and highlight the configured TEDS channel that you want to use to take the measurement. Click Next.
4. Name the task and click Finish.
5. After you create a task, ensure that the appropriate settings are configured in the task. Specifically, check Task Timing (the common setting for the Acquisition Mode is Continuous).
6. You can start taking measurements immediately in MAX test panels by clicking the Test button on the task toolbar.
After configuring the measurement hardware, TEDS channels, and NI-DAQmx measurement task, you can write your measurement application using LabVIEW 7.1 and the NI-DAQmx 7.2 Application Programming Interface (API). Complete the following steps to auto-generate code.
1. Open LabVIEW 7.1. Select New»Blank VI.
2. Right-click in the block diagram to open the functions palette. Select All Functions»NI Measurements»NI-DAQmx Data Acquisition palette.
3. Drag the NI-DAQmx Task Name Constant
or 
and drop it on the block diagram. Move your cursor over the drop-down arrow and click once. Select the TEDS task from the drop-down list.
4. Right-click the NI-DAQmx Task Name Constant and select Generate Code»Configuration and Example.
