Incomplete simulated device list in MAX

I'm trying to create a simulated device (PXI-4071 DMM) using NI-DAQmx 8.9.5 but the list of instruments (see attached picture) contains far less than the list shown in the "NI-DAQmx Simulated Devices" tutorial. Most specifically, it doesn't contain the category "Digital Multimeters" where I'd expect to find the PXI-4071. What drives the list of available instruments? Are there device drivers I need to load to fill out the rest of the list?

A DMM does not use DAQmx so that is why you would not see it listed. You use NI-DMM and it can be simulated if you use the IVI driver.
Edit:
"Install the latest DAQmx drivers. I am running 9.2.3 and it shows up."
You are correct. Never saw that before.

Why does the DAQCard-6026E not show up as a simulated device in NI-MAX 4.3?

I am trying to simulate the DAQCard 6062E in Measurement and Automation Explorer. I have MAX ver 4.3 and NI-DAQmx ver 8.6 installed on a Vista OS. When trying to install simulated DAQ devices, there are no DAQCards listed as options for the E series. I don't know how to simulate this device if it won't show up in this menu.
Thanks

The 6062E (not the 6026 in your subject) shows up for me with the exact same versions of MAX and DAQmx.
p.s. Since your question has nothing to do with NI-Elvis or the student edition, you might want to post similar quesiton to the Multifunction DAQ board.

How to update device list in MAX ?

Hi all,
I'm running MAX 4.0.3 and trying to declare cFP module (that I still haven't received).
I'm expecting :
2 RLY 421 modules,
1 AI 111,
1 DO 401,
they'll be connected to a cFP 2020.
The thing is when I try to add a device I have to select from a list but RLY 421 is not in that list..
How can I update MAX's device list ??

Hello,
I've just installed FieldPoint Driver 5.0 downloaded from NI website but the RLY 421 is still not in the device list ...
Before starting to develop I thought I should update my drivers so I got the latest FP Driver version, but since I'm still using LV 7.1 maybe I shall unistall FP Driver 5.0 and re-install 4.1 and see if it works ?

Creating USB6525 simulated device in max

Can we simulate usb6525 to develop an application while waiting for device to be delivered? Cant see in in the simulated devices list in MAX?
Kind Regards

If it's not there, then use other Digital I/O devices.

Import MAX configuration without device or simulated device

I'm hoping there's a way to do this.
In previous versions of MAX, it was possible to import Channel and Task information without having to import the Device. This was handy if you didn't have the DAQ boards installed on that PC, but you needed to check Task and Channel information.
I'm currently trying to import an .nce file from a project where I'd used a USB6008 as the DAQ device. I don't have access to one of those at the moment and it's one of the devices that cannot be simulated.
I have tried simulating a similar device with hopes of somehow "tricking" it to import. So far, no luck.
Does anyone know of a way I can have a look at the Channel and Task information in that .nce file or possibly fanagle it into importing without or with another simulated device?
Patrick Allen

Hi pallen,
I actually don’t know of a way to change the configuration in the .nce file. It's a binary file which main use is to import and export complete configurations when you do not need to edit that configuration outside of MAX. The .ini and .txt are intended for editing outside of MAX. However you can always import the .nce in MAX, make the changes needed and export a .ini to your final destination. Sorry that this is not too helpful on your current situation.

ENET/100 GPIB0 not displayed in MAX device list

I configured the GPIB0 device as an ENET/100 through the win2k control panel. The unit is on our subnet and passes the diagnostic. However, it does not appear in the Max device list. When I try to add a device manually, ENET/100 is not in the list.

Hello Art,
It sounds like you are using NI-488.2 version 1.2. Version 1.2 does not have MAX support for the enet. NI-488.2 ver 2.0 has MAX support on Win 2k for the enet.

Simulated device in MAX, self tests without error and has working Test Panels, but doesn't show up in DAQ assistant.

I'm trying to create a development machine where we can test new code without using our physical hardware. I've followed this guide in setting up a simulated device. I can get to step 3.2b, but the device does not show up in the DAQ assistant. In MAX, the device self tests and self calibrates successfully, and when I open the test panels, I see some sort of signal. I assume this is a default simulated input since I haven't told the device to look for anything? Note that the two devices I'm trying to create show up in the Devices and Interfaces section, but that even after running Self-Calibrate, the Self-Calibration date is still unspecified.
When I try to test the device and create a voltage input according to the guide, I am unable to see either device in the DAQ task creator.
Steps 1 and 2 of this guide are obviously satisfied. Step 3 is not, but this is unsurprising since a simulated device wouldn't be found in the Device Manager anyways. Also, I am not running RT, so step 4 is satisfied.
Does anyone have any ideas?
Solved!

That would be because the PXI 5124 is a digitizer not a analog input device. You need to use the NI SCOPE driver not NI DAQmx

MAX Simulated Device SCXI-1001

I open "Measurement and Automation Explorer".
Right click on "Device and Interfaces".
Select "Create New".
Select "NI-DAQmx Simulated Device".
Press "Finish".
Expand "SCXI Chassis".
Select "NI SCXI-1001".
Press "OK".
Window "Create New SCXI Chassis" appears.
("Chassis Communicator" does not allow a selection)
"Chassis Address" set to zero
Press "Save".
Window "Chassis Communicator" not picked with message "Please pick the communicating DAQ device."
My system does not have an SCXI-1001 attached. Our equipment is being shipped to the
installation site. We need to continue software development and test.
Can you tell me if I can simulate the SCXI-1001 without the SCXI being attached to my computer?
This function worked when I tried it on the computer that had the SCXI-1001 attached.
Is there a work around for his issue?
Thank you for your help.
Bill

Hi Bill-
In order to configure a simulated SCXI chassis you will first need to create a simulated DAQ card to serve as the chassis controller. I would suggest a simple multifunction I/O board such as the M Series PCI-6221. Please post back if you are still not successful.
Thanks-

Cannot create a simulated device

Hi all,
I am using LV8.0 and MAX 4.0....
I am trying to create a new simulated DAQmx device,
When I right click "Devices and Interfaces" and select "Create New", only Virtual and motion devices are listed.. DAQmx devices are not at all there...
I tried uninstalling and reinstalling MAX.. Still the problem persists.
What could be the problem???
Thanks in advance,
Sahana

Hi,
I have same problem. I try to create a simulated NI DAQmx in MAX, but it is impossible. In create new dialog box, I cannot find any section like Simulated NI-DAQmx Device or Modular Instrument as shown in Figure. How can I add this section in MAX? I installed the latestversion of NI-DAQmx (9.8). Any way, when I click software section it show MAX Database Connection Error, I check the services of Window both NI Configuration Manager and NI Device Loader are running, I also check Window firewall and it also allow these NI program pass throught. I have no problem when installing LabView and NI-DAQmx Driver. Could you please help me?

Obtain the determinate data from the NI-DAQmx Simulated Device

Dear All,
       How to config in MAX in order to obtain the determinate data from the NI-DAQmx Simulated Device?
       For example, the vi will run when the Digital I/O line is High, but using the Simulated Device, the result is random. In another word, I can't set the line is high or low.
       Would you please give me some suggestion?
       Thank you!
Hugo

Here is what I mean of stopping the DAQmx stimulated device. I do from step A - E; and step E is what I mean stopping the DAQmx stimulated device.
3. Use the NI-DAQmx Task in VI Logger Lite to complete a data logging application.
a. Open VI Logger Lite. If you do not have VI Logger Lite, download it or request a free CD.
b. Right-click My System>>VI Logger Tasks and select Create New.
c. Select Using NI-DAQmx and click Finish.
d. Select the NI-DAQmx task for the NI-DAQmx simulated device. Leave all settings in the defaults, and click Run task in the toolbar.
Figure 9. VI Logger Lite data logging task.
The data logging task begins. Data from the NI-DAQmx simulated device is displayed in the Real Time Data viewer.
e. Click Stop task.

Can't add simulated SCXI chassis in MAX

Hi all
I wanted to test some hardware by simulating it on my workstation. I'm using Labview 8.2 and MAX 4.1.0
When I try and simulate the SCXI 1000 chassis, the first dialog box appears with the chassis communicator dropdown control greyed out. The chassis address box is available. When I try and save it keeps asking to select a communicating DAQ device but it doesn't seem to have a spot for that. I don't know if I'm missing something or if I need an update to MAX. Anyone had this issue?
Thanks in advance
Chuck

Hi Chuck,
You're right... the SCXI 1600 cannot be simulated according to the following KnowledgeBase article:
What are NI-DAQmx Simulated Devices and How Do I Use Them?
Are you having trouble simulating any of the other modules, or just the 1600?

Does DAQmx 7.5 allow the creation of an PXI-8464/2 as a simulated device?

I'm using 7.4, but could not find the 8464 in the list of possible simulated devices. Likewise for the PCMCIA CAN cards - can I create these as simulated devices in 7.5?
Thanks In Advance - MJD

Hi Mike,
The National Instruments' CAN hardware is supported through its own
driver, NI-CAN. The NI-DAQ (mx) driver software does not interact with
National Instruments' CAN hardware, only with data acquisition (DAQ)
devices.
However, NI-CAN 2.3
introduced a concept similar to the 'simulated device', where there are
two virtual ports (CAN256 & CAN257) that are connected to each
other. Unlike the 'simulated devices' of NI-DAQmx, those two virtual
ports/interfaces are not visible in the Measurement and Automation
Explorer.
For more information on the two virtual ports, please refer to the readme file of NI-CAN 2.3 or to the Frame to Channel Conversion section of Chapter 6, Using the Channel API of the NI-CAN Hardware and Software Manual.

Simulated Device Aliases should behave like other device Aliases

BUG submission:
Here is a nasty little problem: do the following:
Replace a USB device neatly:
Assign an Alias to a USB Device For simplicity use an NI USB 6008 "MFD1"
Remove the device from the system
Plug in a new NI USB 6008
Run the code here with "Device to rename" = MFD1
require no further action. This is desirable behavior! user's are happy (And if I went to nirvana and wrote the Devmon hook linked from the abResult: Old 6008 becomes "Dev1" New 6008 is MFD1 and existing applications calling resources for "MFD1" ove the swap happened at PnP device discovery)
Similar techniques can be used for a system where one developer delivered a solution using a DMM as "Dev1" and your app call's it "DMM1" Yup, Application specific hardware configuration has a lot of potential!
Contrast that with this:
Replace a Simulated USB device:
Assign an Alias to a Simulated USB Device For simplicity use an NI USB 6008 "MFD1"
Plug in a new NI USB 6008
Run the code here with "Device to rename" = MFD1
Ignore the runtime error
Result: Simulated 6008 remains "MFG1" New 6008 is "Dev1" and existing applications calling resources for "MFD1" are broken pointing to the simulated device.
Simillar problems ocurr when importing a *.nce file (No surprise since, the system configuration API lets LabVIEW act on system configuration methods and properties just the way MAX does)
This bug can be a showstopper for high mix test enviornments with staged test releases.

An alias for a usb device is probably intimately linked to the device serial number. If the devices have valid serial numbers (usb spec says its optional) then what you want wont work because windows will only ever recognise that device with pid vid and serial number exactly matching as being the same device.
Which is why I intercept the connection event and configure NI Device monitor to launch the custom exe to re-name the alias via the system configuration API for USB DAQmx devices (and launch a config import from file in a system rollcall sequence for system hardware that doesn't use the DAQmx expert)
With an alias I could care less about how the OS identifies the resource- its what they exist for

Incorrect Device List AC1900 EA6900

When I look at my Device List, the list is either incomplete, it lists devices that are off-line and it lists several devices multiple times; quite annoying.
Why is that? Any suggestions?
(I do have a none-linksys extender)

mine does that occasionally too. just hit the x to delete the offline ones. I dont find that map very accurate but usually the ones that show online are truly online.

Why can't I see a simulated device in myDAQ assistant?

I have created a simulated device (cdaq 9174) in NI MAX.
I am using the DAQ assistant symbol in labview to create a voltage signal simulation.
When I get to the "select physical channels to add to the task" screen in the DAQ assistant, my simulated device is not showing up, even though I can see it in NI MAX.
Any trouble shooting suggestions?

Hi Dawud,
you should stick with your original thread instead of scattering the problem in different places…
Did you also simulate some modules in this cDAQ chassis?
Why don't you supply a MAX screenshot with your question?
