PCI-6601: Error -10020 at CTR Pulse Config

[Arne May]

Using the 6601 counter/timer and LabVIEW 6.0. Have 2,7 MHz input on all source inputs. Counter0 devide by 2700, Counter1, 2 and 3: Generate Delayed Pulse.vi

Running the vi I get the above error message with this text added: "NI-DAQ LV the timebase is invalid"

If I choose continue it seems to work! What is wrong?

Hello,

I will suggest you to double check the parameters and check them in the LV for valid parameters. Are you using an example VI? I would be willing to look at it if you can tell me where you saw it.

Hello,
oops. Suddenly I realized one thing. You are using a wrong example. CTR Pulse Config, if you see, is compatible with AM 9513 and 8253 chip based counters. PCI 6601 has NI-TIO chip on it. So you have to use the examples (or VIs) related to NI-TIO. Sometimes, the DAQ-STC based examples will also work with NI-TIO based boards.

Running the test.vi below with 2.7 MHz input on all Source inputs and just changing the Counter number give the following results:
Counter 0 -> OK
Counter 1 -> OK
Counter 2 -> Error -10020
Counter 3 -> Error -10020

All counters work OK with internal Clock

Tried with a new PCI-6601, same result.

Using the GenerateDelayedPulse.vi give this problem. Does that mean that this vi does not work with PCI-6601?

Forgot to mention that I am using the NI-DAQ 6.8.0f9 that came with the LabVIEW 6.0. Does it have any effect to use NI-DAQ 6.9.2 that came with the PCI-6601 board?

[Sastry V.]

Hello,
You cannot have both NI-DAQ versions installed at the same time. Uninstall every version of NI-DAQ that is currently present and then install NI-DAQ latest version i.e., NI-DAQ 6.9.2. By the way, before you install the software, take out the card and put it back only after you install the software.

Hello Arne,
Extremely sorry for the delay in my post. See, the Generate Delayed Pulse VI causing the problem is fully justified. IF you open the VI, you will see that it contains a Counter Start Vi(with 123 on it) that is compatible with AM9513 or 8253 chips which were in old cards but not 6601. 6601 uses a new chip called NI-TIO. Hence the VI that is being used (counter start (with 123 on it) on AM9513 and 8253 compatibility) cannot be used for 6601 cards. It clearly says on the functions pallette for counters which VIs are AM9513 and 8253 compatible.
