MAX settings in VC++

[JWilliams]

If I set up the chassis configuration in MAX for the SCXI 1000 to be multiplexed, can I use the following code in VC++ to scan all of the channels on my two SC1102B modules using an NI PCI 6221 card?

In particular, my channel strings may need checking!

      int       error=0;

      TaskHandle  taskHandle=0;

      /*********************************************/

      // DAQmx Configure Code

      /*********************************************/

DAQmxErrChk (DAQmxCreateTask("",&taskHandle));

DAQmxErrChk(DAQmxCreateAIVoltageChan(taskHandle, "Dev1/SC1Mod1/ai31,Dev1/SCMod2/ai31",

"", DAQmx_Val_Cfg_Default,0, 10.0,DAQmx_Val_Volts,NULL));

           ....code truncated to keep in limit

Thanks in advance

John

Hi John,

Have you tried the code that you have posted and it didn't work?


If it didn't have you tried the following for addressing one module:

DAQmxCreateAIVoltageChan(taskHandle, "SC1Mod1/ai0:ai31", "", DAQmx_Val_Cfg_Default,0, 10.0,DAQmx_Val_Volts,NULL

I don't have any SCXI equipment to directly try this at the moment but will try and hunt one out.

Have you been able to read any channels at all yet and if so how were you addressing.

Update:

I notice that this is a duplicate of the followign thread:

I presume this is now resolved?
