How Do I Configure the DAQ Channel Wizard for use with 5B31 modules.

Problem: How do I configure virtual channels in Measurement & Automation Explorer (MAX) to acquire voltage readings from 5B31 signal conditioning modules?

Solution: The 5B31 modules are single-channel signal conditioning modules that amplify, protect, filter and isolate analog input voltages. You can use a 5B31 to read voltage input through the Channel Wizard by following these steps:
  1. Click on Measurement & Automation Explorer; expand Devices & Interfaces and verify that your DAQ board is functioning properly. Help can be found by going to the DAQ Configuration Wizard on our webpage (see link below).

  2. Next, right-click on Data Neighborhood >> insert to create a virtual channel. On Create New Channel window, select "Analog Input". The next window will ask you to Enter Channel Name and Description. Fill it out and click Next.

  3. Next it will prompt you to select a sensor type or measurement type. Select "Voltage" measurement.

  4. Put V (volt) as the unit and enter the input range found on the module as your measurement range. e.g. -10V to +10V.

  5. The next screen will prompt you for scaling method and module output. Because 5B modules automatically map input values to output values linearly, choose the Map Ranges option from the list. From the table on the side of the module, enter the output range of the module. For 5B31, it's either 0V to 5V or -5V to +5V.

  6. The next screen will ask you for information about your DAQ hardware. Choose your DAQ board from the list and choose the channel to which the module is connected. In most cases, this channel will correspond directly to the 5B backplane slot where the 5B31 module is installed. Select the type of input mode you will be using for that channel. Your DAQ board should always be configured in Non-Referenced Single Ended (NRSE) mode for use with 5B Series backplanes. If you are using a board that does not function in NRSE mode, configure it to Referenced Single Ended (RSE) mode and configure your 5B backplane accordingly.

    NOTE: Depending on the type of DAQ board you are using, you may not be able to change the input mode from within the Channel Wizard. If this is the case, cancel the Virtual Channel configuration. Go back to Devices and Interfaces or NI-DAQ Configuration Utility, select the DAQ board used for this measurement and configure it to the proper input mode. You may have to shut down the system and reconfigure jumpers located on your board.

  7. Press the Finish button to complete the channel setup. You will be taken back to the main Measurement & Automation window. If you expand Data Neighborhood, you will now see the virtual channel you just configured. You can click on the channel name to verify all the information entered. Right-click on the channel and select the test button, you should see the appropriate voltage readings displayed in a graph format. If this is not the case, it might be that you either selected the wrong input or output voltage range. In this case, you can right-click on the channel name and select properties, make all the necessary changes and test again.
