error 50103

[InasLab]

Hi there,

Can anybody help me please... I'm not so new on labview and never had a training. I am trying to rea measurements from different temperature sensors using NI9203 channels and also i'm generating output signal from NI9263. I need to see all temperature running at the same time but when i run labview i get error 50103. I have tried all steps mentioned on previous report ofsuch error but still cant get my measurements.

Please help me...

I'm guessing that you are using a cDAQ-9172 CompactDAQ chassis.  You are getting a resource reserved error because you can only have one hardware timed analog input task and one hardware timed analog output task running at a time.  Looking at your VI, it's a simple fix.  You'll want to add all of your analog input channels, for example, to the same DAQ Assistant block.   Just open it up and click "Add Channels".

Hey thanks for the prompt reply. Yes I know what you mean, and had done that already, the problem is that i want to have individual display for each signal. And that way i can only manage to have a graph with 23 signal, that way i am not able to see clearly the variations in each channel as i would like to... is there a way I can use somethink like a demultiplexer to read each channel individually?

Thanks

Right click on your data wire.  Select "Signal Manipulation Palette".  I'm fairly certain "Split Signals" will do what you want.

Thanks for your suggestion. I never new there was something called split signals "I'm so used to matlab that i thought it would be callex mux/demux".

I still can not do that for the NI9263 it says "Error 200524" More tasks than it is allowed. I want to control a selenoid, and some actuators but i dont know how to make all work simultaneously in one block.

Please have a look at my file

Error -200524 does not say 'more tasks than it is allowed'. The exact error message is:

Measurements: Write cannot be performed, because the number of channels in the data does not match the number of channels in the task.

In the example you posted, you are doing a single analog write with a DAQ Assistant you called DAQ 9264. Are you using a 9264 or 9263? You mention multiple actuators and a solenoid. Since you are only writing to a single channel, did you post the right code?

[InasLab]

well, you are write it doesn't actually say that, it's just what i understood it was happening. But the right message is the one you posted. I am using an 9264 which is the same as 9263 but with more output channels. Yes I am trying to drive 4 devices (a selenoide, and 3 actuators) as my hardware is conected to those. They all need a voltage signal to be driven that's why I am try to run 9264 with 4 or 5 channels at the same time.

The attachment is the current code I have...

Looking forward to hearing from you

Thanks,

Now the error makes sense and the cause is exactly what the message says. You have configured the DAQ Assistant for 4 channels. The input is a single DC signal. You need a signal for each channel.
