SWITCH and DMM Handshaking in simulation

[kdCMC]

Hey,

should the SWITCH DMM Handshaking example work in simulation?

I'm thinking the triggers aren't comming through from SWITCH to DMM and/or the other way round.

Simulating the chassis and the SWITCH and DMM.

I didn't try simulating only the SWITCH in a real PXI setup yet. I'm only lacking the SWITCH.

thx,

Koen.

Hi kdCMC,

Just double checking, is this the example in LabVIEW?

I know this VI waits for a digital pulse from the switch before taking any measurements, and am not sure if this can be simulated. In the 'NI Switches Help' reference, I found the line "If simulation is enabled, instrument driver functions perform range checking and call Ivi_GetAttribute and Ivi_SetAttribute functions, but they do not perform instrument I/O"

Perhaps someone else knows for sure.

If you want to give it a go, there's a tutorial on 'Creating and Using Simulated Switches':

Out of interest, what do you need to simulate this example for?

Best regards,

Leah

Good day,

thanks for the answer.

I used the alternate method described in the doc to simulate the switch and the dmm.

It is the example of labVIEW.

The example works as is (continuous scan & # of triggers to 0 with dmm in measurement loop: backlog # > 0. But I want a specific # of scans as specified in the scan list -> # of triggers == # entries in the scan list & continuous scan to F. Without dmm in a measurement loop, but once retrieving the # of measurements (which should be equal to the # of triggers == backlog #), but the backlog stays at 0 (& measurement times out).

I will try to only simulate the switch into a real PXI setup which I've got, but I'm missing the labVIEW PC right now. I will try this when I have back that PC (within a week).

thx & regards,

Koen. (I want to measure shorts and opens in 2 scans, one scan for the opens & one scan for the shorts on a 2535 FET MUX 136 columns switch linked to a PCB.)

it works outside simulation, with real physical DMM 4065 & 2535 FET MUX on a PXI1078 Chassis with remote controller(oem PC).
