Recently, I have brought a 12/16-bit multifunction card which in PCI-1710 series and terminal wiring board which is PCLD-8710. I am using Labview to control my multifunction card. While I use the analog input channel to get three sensors’ signal at the same time, we face the following problems:
1. If we connect the three analog input signals to channel 0, 2 and 9, this set of connection cannot function. We can’t get any analog input signal. Even through we disconnect the signal which in channel 0 and 2, we still can’t get the correct input signal continuously. In the program panel, the signal was oscillating. The signal would then suddenly drop.
2. If we connect the three analog input signals to channel 0, 2 and 4, we can get all analog input signal correctly.
3. I have written a program and it consist two parts. The program aims to read the analog signal from three different channel at the same time (real time). When these two parts run separately, it doesn’t have any problem. After I combine these two programs together, it doesn’t work. It seems that the function which can read the analog signal cannot appear more than one time at the same program.
Questions: Why such situations happened? Is it mean that we should connect all the input signal start from channel 0 and then channel 1 and then channel 2…… ? Could you give me some examples which can read multiple analog input signals at the same time?
Thank you for your help.
