Do I need to configure something different,when I'm using SCXI-1000,1102 and 1180, together.?

[santos_jose_b@cat.com]

I am wanting to use SCXI-1000 with 2 modules SCXI-1102, but I also want to access the DAQ (ni pci 6035), through the SCXI-1180, to access some Digital I/O. How can I do that? What cable type between the SCXI and DAQ (6035) do I need to use? Do I need to configure something different? When I only configure the SCXI-1000 and SCXI-1102, I use the cable with 68 pins in both extremities and I don't have problems. But when inserting SCXI-1180, a following error message it is generated:

"Dev1" digital lines 0, 1, 2 & 4 are in use by the connected SCXI subsystem.

It happens when observing DIGITAL I/O in Test Panel in M A X.

Hello Bras,

I think the following article will explain why you are receiving the error message. Digital lines 0, 1, 2, and 4 are actually used for SCXI communication.

Thanks for the information! The examples sent me, were useful, but always I use Digital functions, just after I can't perform tests with SCXI, it doesn't respond, it becomes inactive until I reset Traditional NI-DAQ Devices.What can I do to have the VI attached running well? Can you help me?


thanks

Hello Jose Bras,

The reason that you need to reset the Traditional NI-DAQ Devices is because you are using two different drivers in the same program, Traditional and DAQmx. Your Digital Writes/Reads are done using Traditional DAQ but your SCXI code is done in DAQmx. I would recommend that you use DAQmx to program your Writes/Reads.

Take care,
