Daqmx Read - 2 Digital In Cards 1162_1

[MikeW1973]

Hi,

I have a DAQmx Read "Analog 1D DBL NChan 1samp" which i feed with a channel list which spans four 1102 cards & one 1126 card (all in an SCXI 1001 chassis) , this seems to work perfectly fine (they are set up as simumlated devices at present). I have now added a DAQmx Read "Digital 1D bool NChan 1samp" to my labview project and it will not span two 1162 cards. It says the following

One task cannot contain multiple independent devices.

Create one task for each independent device.

Device: SC1Mod8
Device: SC1Mod7

I find this strange as my Analog DAQmx Read uses channels from Devices  SC1Mod1,  SC1Mod2, SC1Mod3, SC1Mod4 SC1Mod5, SC1Mod6 & SC1Mod10 and that works fine

Any help would be apprecatiated as I dont really want to set up an extra task for the other card

Cheers

Hi Mike,

Unfortunately, there is no way to configure digital channels on separate SCXI Modules in a single task at present. Within a single task, you can only configure multiple digital channels on a single device.
