Error number -50103 for NI PCI 6229 for analog input(Voltage) task

[Nagraj B]

    I am using PCI 6229 and CVI for the development. I have crearted two analog input task.

1. Voltage - I am using ai0 and ai1(differntial)

2. Voltage - I am using ai2 and ai3(differntial)

When I start both the the task I am getting the error number -50103. The specified resource is reserved.

Can anyone help me to solve this issue

Regards

Hey,

Since the 6229 is using a multiplexer to switch between the channels and just one timing engine for AI you cannot create two AI Tasks running at the same time.

See if you can put this two measurements into a single Task.

I am having the same problem, I am using the BNC 2110. I want to read in two separate voltages and convert them from dynamic data into numeric. I used the advice posted above and I am able to view both voltages on a waveform graph but now I am only able to convert data from one of the voltages. The DAQ Assistant does not provide an extra output for the second voltage I wish to also convert What do I do? I have attached my code

First: the BNC 2110 is just a dumb connector block "The NI BNC-2110 is a shielded connector block with signal-labeled BNC connectors. You can use this connector block with NI X Series, M Series, E Series, or S Series multifunction data acquisition (DAQ) devices and NI analog output devices."

Second: Look on the functions pallette under Express>>Signal Manipulation>>Split signals. This will seperate your Vs from your Vi.

Yes sir , that worked perfectly...(the split signals VI).

I forgot to say Thank you!
