PXI-2548 relay module calibration

#1) Where would I find the date when my PXI-2548 relay module was first calibrated?
#2) Are there different ways to calibrate the this relay module and if so what are they?
#3) How often should this relay module be calibrated?
Thanks,
Julian

Hi Julian,
The NI PXI-2548 does not require calibration because it does not have any electronic components that can get calibrated. Therefore, there is no calibration done, there are no ways to calibrate the module, and there is no calibration schedule.
Note that you can compensate for the insertion loss of the switch on a per path basis. These compensations typically include the loss through cables and are performed when the board is placed in the end system. This is more of an offset compensation for the system "switches+connectivity" rather than a board calibration; it is system dependent. I recommend making this compensation measurement before proceeding with any automated testing.
Hope this helps!

Where i can find exemples for PXI-2564 relay module

hello,
I'm beginner in PXI module using.
I bought a PXI solution for use it as a custom instrument.
My aim is to read RTDs and command some line using relays.
So i take the system below:
NI PXIe 1071
    PXI-8100
    PXIe-4357
    PXI-2564
I can see all the material on NI MAX.
In MAX, i can read RTD a channel value and can operate relays.
i have read and practice exercice on "Getting started with Labview RT module" and all it works,But i don't find any resources or exemple to deal with relay card or read RTD.
I have try to access it using "visa connect" and this step works, but what must i do to go further.
In a first time i want to swap relay position, by reading position, invert value ,set position and return the value.
And for RDT i'll want to make a simple measure and make a average a N measure for 1 or all input.
Can you give me some exemple or trick?
Best regards

Hello,
What software do you use? what version?
Have you look into the LabVIEW Example Research with KeyWord "Relay". There are examples with NI-DAQmx and niSwitch drivers.

Accessing the 40MHz clock on the PXI-7831R FPGA Module

How do you access the 40MHz clock on the PXI-7831R FPGA Module?
I'm trying to the FPGA to do RS-422 communication with UART and HDLC protocols. I want to divide the clock signal to generate the necessary baud rates. I've downloaded the FPGA serial examples as a start, but I'm looking for a direct connection to the 40MHz signal.
I'm Using LabVIEW 7.1 and FPGA Module 1.1 with the LabVIEW Embedded Project Structure.

settlesj,
If you are looking to have access to a 40MHz digital signal, it is possible to generate and acquire one using 7831R and LabVIEW FPGA module. To do this you would need to take advantage of the different compile speeds available with the FPGA module. The available compile clock frequencys are: 40MHz, 80MHz, 120MHz, 160MHz, 200MHz
For example to generate a 40MHz pulse train you could compile with 80MHz clock frequency (2 clock pulses are needed for a square wave period).
You will have to be careful when generating code because compiling with a clock frequency higher than the default one (40MHz) could give compile errors in some cases. These errors could happen more frequently if the code is more complex and needs more time to be executed.
I have attached an example program that generates a 40 MHz signal on a digital line. From there you could divide down the clock rate to which ever specified baud rates you needed. As a side not the LabVIEW FPGA 8.0 Module added the ability to derive additional clocks from FPGA base clocks in a LabVIEW project. Hope this helps.

Analog signal change(module 9381) in labview when activating switch on relay module (NI9481) on seperate circuit

We are getting analog voltage changes in Labview on several different inputs (not found with multimeter). It happens when we activate the NI 9481 relay module with a 24V DC signal to power a solenoid. Don't understand why this is happens or why it shows on three different inputs in LabVIEW but not when testing the points with a meter.

That picture is of little help, since the devices will report what they measure, wether it is the voltage of interest or not
To find the root cause of that effect, you 'just' have to follow the current. However current and to note _fast changing current_ can go funny, not always so obvious ways.
That's why I asked for details of the setup, and every wire counts
(and ground is a con...... see sig)
And a as fast as possible sampled voltage channel while a switch is actvated (say 20ms) would help too.

Are there any relay modules available for Compact Fieldpoint, and if not, what are the alternatives?

I'm speccing out a Fieldpoint system, and although Compact Fieldpoint has many features that make it superior to Fieldpoint for my application, I'm wondering why no relay modules seem to be available for it.
The cFP-RLY-420 is referenced in the manual it shares with the FP-RLY-420, and a search in the product section comes up with several pages that aren't viewable, but it doesn't seem to be currently available.
More importantly, if there are no relay modules available at this time, what would be the alternatives for switching? A small Opto22 backplane wired to a DO module perhaps?

Mako,
Several of the more specialized modules in FieldPoint have not yet been released in Compact FieldPoint. However, National Instruments is presently working on releasing most of these traditional FieldPoint module in the future.
Depending on your application, either the cFP-DO-401 or cFP-DO-410 (which are both providing sourcing outputs) may be a possible alternative. The DO-401 module can sustain up to 2 A per channel, 8 A squared per module whereas the DO-410 can sustain up to 1 A per channel. Please note that these modules only handle low voltage DC.

Relay module and DAQ Assistant

Hi everyone!
I'm a Labview beginner and currently dealing with a priori easy business. Recently I got a USB Relay Module to be incorporated in an alarm system. Let's say if one gets a certain value bigger than other, the relay should close and activate a siren (see example attached). For this I've used the DAQ assistant and configured one of the module output channel. By using a simple boolean switch, I can easily close and open the relay. However, if I use a case structure, an error is obtained, as the DAQ Assistant for one output can be only used once. I mean, if the relay is closed and I'd like to get back the original situation, i.e. opened relay, what should I do?
Schematically:
-if A>B, then closed relay
-if A<B, then opened relay
Sorry for the messy explanation, but I think you get the point.
Thanks in advance

I just got it. The problem was that in the main vi, not in the example I attached, the same output via DAQ Assistant was configured for two different case structures. Obviously the relay module was going completely mad, since I had two independent pairs of TRUE and FALSE working at the same time. If I get, for instance, TRUE for one case structure and FALSE for the other, the switch doesn't know what to do. Hope now it's clear...

NI TB-2605 terminal board to NI PXI-2503 relay card pin GND interconnect?

I am using the NI PXI-2503 relay card and the NI TB-2605 terminal board to impliment some interconnects My question is on the terminal board there is a GND terminal listed on pin GND. What electrical pins or internal backplane or relay card terminal does this "point" interconnect to?
Solved!

Figuring this internet stuff out is not for the feignt of heart....!
First....thank you for your initial effort.
I am a test equipment engineer.
As you probably know, I am confused with the threads through the documentation. I am looking at the figures provided on the TB-2605 Isothermal Terminal Block Installation Guide, Figures 1, 2 and 3. I am also looking at the NI PXI-2503 Specification pdf figure 1.
There is no mention of a GND connection connected to the Relay card Figure 1. This GND may go into the PXI chassis backplane and mate to the power cord neutral line or some other connect like that, but I cannot tell.
I would like to peice together a guide to my manufacturing people as well as to my software people how this thing works using software to select 1 x 48, 2 x 24, and dual 2 x 12 switching modes when I specify the use of this fine equipment for solving our test needs.
I beleive that I am close, but a very few questions remain.
Thank you for you excellent approach to "looking" into the answer for my question. Any additional insite to GND paths is appreciated.

PXI-2501 relay life

Hi,
I would like to know the relay life of PXI-2501.
For PXI-2503 and others, I can find the relay life (electrical and mechanical) in its specification manual, under Dynamic Characteristics. However, I cannot find the relay life for PXI-2501 under its specification manual, under Dynamic Characteristics. Could anyone tell me the relay life of PXI-2501 (for both electrical and mechanical)??
Thank you & Regards

MAX does not recognize PXI-4056 DMM module with PXI-1033 chassis

New to NI PXI chassis. Using the PXI-1033 chassis with several installed modules. I am able to see the chassis and two of the modules in MAX, but my PIX-4065(DMM) module is not listed/found. Any advice?

I have to ask the stupid questions first. Do you have NI-DMM installed in your computer? Is the DMM card fully inserted (I have seen people not lock the card in and expect it to work)?
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

SbRIO & 9205 C module : calibration validity

Hello,
By using LabVIEW, is there a way to get calibration information for a 9205 C module used with an sbRIO-9612 ? (last calibration date for example, or at least a boolean information)
I know that we can get this information with MAX functions when 9205 is used with a cDAQ. But is it possible to do such a thing with an sbRIO and if so, how can I do that ?
Thank you in advance for any answer.

My PXI-5401 was just calibrated, but Vpp is off 17%

Hi,
Using the FGEN-SFP software I specified a 4MHz 500mVp-p sine wave and set up the load impedance as >1M. When I scope directly on the output, I get a 582mVp-p signal. I tried this on another station to confirm and get a 542mVp-p signal. The scope is a LeCroy LC534A 1GHz model.
The spec on the device is +/-0.1dB which works out to 1.16%, or 494 to 506mVp-p at 0 offset.
This indicates a problem with the calibration to me. Is this a fair assessment? My setup is as simple as possible, do you see any error in my methodology?
Thanks.

Hi, bmaxton.
This issue may be associated with the cable that you are using. Try using a different cable. It is also possible that the PXI-5401 and/or scopes need to be re-calibrated. Confirm that the scopes are calibrated correctly by applying a known voltage.
What is your operating temperature? This could also affect the accuracy of your reading.
I hope you're having a great day!

Why are my PXI cards not recognized by Windows or MAX?

I have a PXI-1045 chassis connected to a PC through MXI-4. When I turn the chassis and PC on with a PXI card in slot 2, the message "Windows could not load the installer for DAQDevice. Contact your hardware vendor for assistance." appears, and the PXI card is not recognized (it is scene by Windows as an unidentifiable PCI Devices, though I have a DAQmx installed).
More details:
Windows XP
LabVIEW 8.0 installed
TestStand 4.0 installed
Latest DAQmx 8.XX installed
NI Scope installed
NI CAN installed
MXI-4 PCI card installed in PC and recognized by Windows (as PCI-PCI bridge, and MXI-4 Device)
I identified PXI chassis 1045 in MAX and on subsequent boot up saw that MAX complained about pxisys or some other ini file (in the chassis status area of the screen) so I configured it as 'other' then put in the PXI-resorce CD and selected the ini file for PXI-1045, MAX no longer complains about pxisys and instead says the chassis is configured properly
If I have nothing but the PXI MXI-4 card installed in the PXI system and boot up the chassis then the PC, I get no errors
If I have a card in slot two (I've tried PXI-6509 Industrial Digital IO, PXI-2569 Relay Module, and PXI-5102 Digital Oscilliscope) and boot the chassis then PC, the message "Windows could not load the installer for DAQDevice. Contact your hardware vendor for assistance." shows up when Windows boots and Windows sees a PCI Device but can't identify any drivers for it.

Hello,
Can you post a screenshot of the problem? Are you switching on the chassis first or the PC? Please make sure that you switch ON chassis and then boot the PC. This typically happens when you have a corrupted installation. I would suggest downloading the latest version of driver from here and re-installing it.
Please uninstall all the driver software from computer before installing the new software.

How do you configure multiple PXIe chassis to share Tclk synch with the 6672 timing module?

Hi,
I have two PXIe chassis, each with a number of digitizers (configured through NI-SCOPE). Each chassis has a PXIe 6672 timing module. I have downloaded the sample VI from:
http://zone.ni.com/devzone/cda/epd/p/id/5254
which deals with PXI chassis. My question is this: in the VIs at the above link (and in fact all VIs I've seen for using the 6672 for sharing triggers), the VI needs access to the resource identifiers for both Master and Slave timing modules, how do I access the (remote) slave resource identifier from the master chassis? I feel like I'm missing something obvious, but can I do this using just an ethernet connection, or do I need another module to enable the master chassis to view the devices on the slave chassis in MAX?
Thanks for any help you can provide,
Cillian

Those example VIs are written to be used when a single host PC is controlling multiple chassis so there is just one computer running the program. Since both of your chassis have their own controllers it will be necessary to run a program on each (one as master, the other as slave). You can modify the code from that example to create and Master and Slave VIs. For the Master you will call the VIs as specified in case 0 of the example; for the Slave you will call the VIs as specified in the default, 1 case of the example.
You will also want to send a signal from the Master to the Slave to let the Slave know that the clock is being generated. You could use TCP/IP or a PFI line to do this. The basic order of events should be as follows:
1. VI runs on Slave to configure it to accept a clock.
2. VI runs on Master to begin outputing the clock.
3. Master sends a signal to Slave to let it know that the clock is being generated.
4. Continue with the rest of your program.
Let me know if you have any questions about this.

How can i find out the resolution and accuracy of PXI-6602 module?

I have a 32 bit 8 channel PXI-6602 counter module. PXI card is interfaced to PC with MXI-4 link. How can i find out the resolution and accuracy of this system.What is the maximum accuracy and resolution i will get from this system. Because optical signal to cmos conversion signal is given as a input to the counter.

Hi chandhu,
Were you referring to the accuracy of the count register or the timing clock?
PXI-6602 specifications can be found in the NI 660x Specifications. The resolution of the count register is, as you’ve noted, 32 bits. This corresponds to a maximum count value of 4,294,967,295. As long as all of the edges are in accordance with TTL specifications, the accuracy of the count register is 100%.
On the other hand, the PXI-6602 baseclock accuracy takes on the baseclock accuracy of the PXI CLK 10 signal. Again, this is all found in the specifications.
You may also want to check out the NI 660x User Manual – it contains a lot of details on the operation of these counter/timer devices.
I hope this helps. Please post back if you have further questions.
