Analog input block Simulink Desktop Realtime
6 views (last 30 days)
I am using Simulink Desktop Realtime on Windows platform to acquire sensor data from force torque sensors through National Instruments data acquisition card PCIe 6363. As long as I use one force torque sensor, I use only one connector board (i.e. connected to Connector 0 of DAQ with analog input channels AI 0 - 15) and I use Analog input channels [1,2,3,4,5,6] corresponsing to ai0, ai1, ai3, ai4, ai5 respectively and I can obtain the desired response.
But since I have two force torque sensors in my application, I have to use the second connector board for more analog channels, so the moment I use the second connector board (Connector 1 of DAQ with analog input channels AI 16 - 31) and update the analohg input channles in the analog input block of the Simulink Desktop Realtime from [1,2,3,4,5,6] to [1,2,3,4,5,6,16,17,18,19,20,21] I still get the response only from one sensor connected to connector board 0 (AI 0-15). There is no response for the second sensor.
My udnerstanding was when the board is installed, it is known whether both connectors are in use or not. But I am missing something completely and could not find any solution to it from the documentation. I would like to know how can I make my simulink model pick up the analog channels of the DAQ card for both the connector boards? Do I need to specify use Connector 0 and Connector 1 somewhere? If yes, from where can I get this option please? Or do I need to setup something in the configuration of the model ? I would really appreciate any help in this regard. Thank you.

this should indeed work, with no additional setup required. But please verify the setting of the A/D connection option - to be able to use 32 channels, this should be set to single-ended.
Good Luck, Jan
