hardware conflict

[Arter]

Good day,

Firstly sorry if I have some orthography errors in this explanation.
 
I am working with the following three modules:
USB-1608FS (used as analog inputs)
USB-ERB08
USB-3110 (used as analog outputs)
 
I've made the complete program in DASYLab, and I have changed block size, frequency etc. In summary, the three modules work well, though separate, so my problem is the follow:
 
When I put in DASYLab the three modules in the same program (circuit), The input voltages that I get from the USB-1608FS module are wrong, I don’t know why, because in the window of module configuration, I get correct values (between + / - 1V), but in the main window (where the whole circuit), I put a digital display and it display me that the data is between 17 and 22V. I can also say that the other two modules are working properly, while the USB-1608FS gives me erroneous data.
 
I would also say that I have another program (circuit) in DASYLab, which there is only used the USB-1608FS and this display correct data. So, I modified that program (in which the USB-1608FS works correctly) deleting all and I did there the whole circuit again, including also the other two modules; but, when I  try to put play to the program, this give me the follow error " The Module of analog output (or digital output) is standby, maybe the configuration is different" (The program that I use is DASYLab in German and I think this is the translation of the error, I don’t know how the error is written in English) and with this, I do the following: I go to menu measurement -> Measuring equipment options -> MCC-DAQ -> hardware options ... and before that the window of hardware options appear, another window appear and it says that there is a conflict Hardware. (I think here is the error, but I don’t know how to solve it), when this window appear,  I only push "ok", and I see the properties of the other three modules, I only push "ok" again and I return to the main window, and before to push play again, I modify the block size and frequency as I need (because these properties are modified automatically after to be in the window of hardware options) at the time of entering the hardware properties, these are changed automatically) and the program (circuit) works, but the USB-1608FS module starts to give me wrong data, and I don’t know how to solve it.
 
I hope I have explained me well, and that someone could help me.
 
Thanks.

Arter,

First, verify in the MCC-DAQ hardware settings that each device is correctly configured for the number of bits. The problem that you describe with the MCC-DAQ Analog Input properties dialog correctly reading data, and then the worksheet displays bad data, is usually because the driver defaults to 12-bit, not the correct 16-bit.  

The new MCC-DRV driver that shipped with V11 does not have this default. It correctly sets each device to match its capabilities. The older driver does not have that same information.

I would also recommend that you contact your reseller. They should be able to contact Measurement Computing, and provide you with direct assistance in diagnosing problems.

Yes, that was the error, uuufff....

Really thanks for your help, and a last question, why 16-bit and not 12?

Thanks

Please look at the specifications for your devices. The USB-1608 is a 16-bit, 8 channel multifunction DAQ device. Measurement Computing also sells 12-bit, 14-bit, and 24-bit devices. The number of bits determines the resolution of your measurement. The smaller the number, the coarser the resolution, the larger the number, the finer the resolution.

The new MCC-DRV, included with DASYLab V11, resolves the problem of having to know the "bitness" of your device. It's automatically configured, along with other features that vary from device to device.

Thanks for the explanation.
