Looking for a versatile NI counter/timer card + 4 DAQ channels

[Jonas 65]

Hi everyone,

I am a beginner with LabVIEW and for my application I would need a NI PCI card that would have both counters/timers (like the NI PCI-6601) and two 12-bit DAQ channels. I looked through the S and E multifonction series, but they don't have enough counters/timers. Therefore, I consider buying one DAQ card and one PCI-6601.

Do you know if having several PCI cards used within one LabVIEW application can be troublesome ? I already have a CAN card and another DAQ card in my computer.

Thanks in advance.

Right, the max counters on the newer boards is 2. The older legacy cards had 3 counters and the AI/AOs. The only difficulty I've found with stacking a bunch of cards into a box is running out of DMAs and IRQs. That is to say, with a video card, and ethernet card, a sound card, all the normal stuff (mouse, keyboard, system resources) and 4 DAQ cards (aside from box crowding), you can find yourself short of Interupt Request and Direct Memory Access settings to accomodate all this, which means resource conflicts as multiple cards get assigned duplicate settings. Performance wise, I haven't seen any issue with doing this.
