Trigger Input Occurred status in MAX

We are configuring a new closed loop stepper setup with PCI 7344 and the "Trigger Input occurred" led in MAX is turning red after a search for encoder index. The "Encoder Index found" led is green.
What does mean "Trigger Input occurred" and what kind of misconfiguration can cause it?
Tanks.

Hello TulioB,
Thank you for using our discussion forum. Trigger inputs, or high-speed captures, capture the precise position of the motion system when an external trigger signal occurs. You can enable or disable the trigger inputs from the Advanced tab under 1-D Interactive in Measurement and Automation Explorer. The trigger configuration can be selected on the Breakpoint and Trigger tab under Axis Settings. Trigger Input Occurred Led being red will not have any effect on the motion of your stepper motor. I hope this helps you out. Have a great day!

How to use SMB trigger input on PXI-8187 in LabView

Hello!
I have PXI-8187 controller instaled in PXI-1031 and two PXI-4071 digital multimeters. I want to trigger mesurement with external trigger. One way is to used AUX port on DMM, another can be TRIG input on PXI 8187 CPU unit. Is possible to use this possibility in LabView 7? How?
Best regards!

There are multiple reasons why this is not a supported feature for triggering under Windows and why NI does not recommend using the controller's SMB connector for this purpose. National Instruments has hardware that was designed specifically for extremely accurate clock generation, synchronization, and triggering between PXI chassis (PXI-665x) and other recommended alternatives listed below.
Non-deterministic propagation delays
1. The controller's SMB input is not guaranteed to have a defined propagation delay to the backplane. This means the SMB trigger on the Windows PXI controller is useless for customers that want deterministic triggering. Unlike our PXI-665x boards which have a maintained API and precise triggering properties, the PXI controller's SMB connector and routing circuitry is intended for Watchdog use under LabVIEW RT and isn't designed for this use case. A trigger propagating through the SMB circuitry and going to the backplane, or vice-versa, could have a great deal of variance in the propagation delay which makes gathering useful triggers impossible. This propagation delay is not something National Instruments specs.
An excellent available workaround: Use the measurement hardware's trigger inputs
2. The triggering inputs on our measurement hardware (that customers likely have in their system) can route triggering signals to the PXI backplane (usually through PFI lines) with deterministic results. This functionality is fully supported in most of our APIs and will be maintained between generations of devices.
NOT backward or forward compatible
3. The SMB input is NOT guaranteed to be compatible between different versions of our PXI controllers under Windows. The hardware properties along with an excellent workaround are the reason we do not support doing routing of triggers through the SMB connector on our PXI family of embedded controllers under Windows. If you are still interested in the beta software despite the shortcomings, visit www.ni.com/support and submit an e-mail request.

I cant publish anymore: unknown business catalyst error has occured: status 403, 107003

i just accepted the new adobe policy and now i cant publish anymore. When i click on publish this error pops up: unknown business catalyst error has occured: status 403, 107003

Hi, Aish,
That cleared it up, thanks for the quick response. You might consider sending an email that lets users know of this issue. I would never have figured it out. I don't often log on to the main Adobe site.

How to sample a data input waveform with a trigger input waveform

Hi,
I am using the NI USB-5132 digitizer to receive two inputs: one is an analog data waveform and one is a digital trigger waveform.
Is there a way to generate a third waveform/array of data that corresponds to the data waveform being sampled only once per rising edge of the trigger input?
-Thanks

Timothy,
First of all thanks for the reply, I've been really busy this last week and haven't been able to reply.
Right now I have my data signal on channel 0 of the NI USB-5138, and I have the trigger on channel 1. I have attached two corrections of how the signals look coming in (one is zoomed out, one is zoomed in, trigger is the red one the zoomed in one). The trigger signal has 128 square pulses per scan that correspond to the time that I would like to sample 128 different high values for the data input. I also have a 3rd input which has a falling edge for the start of each scan. As you can see in the zoomed out waveform graph, the data input consists of consecutive scans of data.
My end goal would be to process the data so that I have 128 different arrays of 10-20 data points (each data point represents a different scan), with each of the 128-array corresponding to a different element in the 128-long scan, and how it has changed over time. So for example, if the data at array location 3 changes from 0 V at scan t0 to 2.5 V at scan t1, then back down to 0 V at scan t2, then I would like to have an array that looks like:
Array of data for location[3]
Time: t0 t1 t2
Voltage: 0 2.5 0
My biggest challege has been setting up these arrays. Would it be best to capture 10-20 scans using the 'Acquire N Samples', and then do post processing? I also experimented with the PtbyPt VIs, which seem interesting because I would like to do as much of my work in real time as possible, but I'm not too familiar with these or with Labview.
Any help would be much appreciated.

Having trouble figuring out how to use trigger inputs as a general purpose input.

I'm trying to use "Trigger 1" as a general purpose input to indicate the status of external circuitry. I can't seem to get the "Read High-Speed Capture Status" to indicate anything. I'm using the "Configure High-Speed Capture" VI with the capture mode set to Inverting Digital Input, and that VI feeds into a Do-While loop which contains the "Read High-Speed Capture Status" VI, which has the Ret Vect set to 0. I see from the online help that the High-Speed Capture function is available on Servo and Closed-Loop stepper systems, which I suppose is to enable the ability to read the position of the encoders. I'm using an open loop stepper system, so are these High-Speed Capture fun
ctions unavailable even though I'm looking only for status (Trigger 1), and not concerned with reading position? Thanks in advance, Rob.

Thanks for the answer Ken. I'm going to try a different workaround. The global was too slow, and I think I'll break my subVI into two parts. I'll create a sub that has all the setup stuff in it, then embed the actual "check trigger status" loop in the main VI. The loop contains only 2 or 3 nodes. Too bad LabView works this way. I can see one reason it should, but another larger reason it shouldn't. Wishlist.... Oh, speaking of wishlist, I like the improvements that 6.0 has brought, but one thing still bugs me. There's no way to have LabView remember the place to look for files when it's first started. It defaults to "My Documents", which should be, as all LabView programers know "LabVIEW6\user.lib" (or whatever). Of course, once th
ere, LabView remembers for that session. Next time it's started, back to "My Documents" again. How 'bout fixing the "Options", "Path" settings so that it will actually remember the path set? Am I missing something here, or does it have anything to do with the fact that we're using Windows 98? My buddy's using NT, and his works the same. Is there a way around this? TIA, Rob.

Re: Sales Order Output trigger after Overall status is Complete

Hello Friends,
We have a requirement where in , we want to trigger the Sales Order Ouput once the overall status is completed.
Basically , the print program should trigger only when Overall status of Sales Order is Complete.
Can anyone suggest any way to achieve this requirement ?
Thanks in advance.
Julie.

Hi,
For this we have to go for ABAP development/a "Z" program.
This program/conditions will be maintained at the smart form level.
This has to be triggered only when the over all status is complete.
This thing we have to check in table "VBUK".
Pass your order number into "VBELN" and check for the field "GBSTK".If it is "C" then only it should be triggered.
We have to write a small line before this triggering program or condition is to be maintained in smart form if you are using it.Contact your ABAPer.
Regards,
Krishna.

Trigger input point in cvs 1450

hiiii i am using cvs 1450 first time. i have a proximity sensor which is giving 24V output. i want to trigger camera to take picture when i get output from proximity sensor. But i do not at which point i should connect output of sensor to trigger camera. Please told me the point where i can connect output of sensor on cvs.

You can connect 24V signals to the isolated inputs of the CVS.
You will find more information at the CVS-1450 Series User Manual

What is the PCI-1422 external trigger input impedance?

I wish to drive this line and would like to avoid mismatch problems.

The trigger lines on the 1422 go straight into TTL buffers which have very high input impedance (in the megaohm range).

Analog Trigger Input - PCI 6010

Hi everyone,
I have a PCI-6010. I'm programming in VC++ and DAQmx.
It seems to be a simple task, but i cannot seem to accomplish it by myself.
I would like to bring in an analog trigger signal and count every rising edge of this signal.
Does any one have already made something similar?
Hope someone can help,
Thanks a lot,

Hello Eloise,
I have made some research and i was wondering if I can input my 2V analogue trigger in the PFI0 channel, i just want to use it as a trigger to ouput a waveform.
The basic code would be like:
//Create task and output channel
DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
DAQmxErrChk (DAQmxCreateAOVoltageChan(taskHandle,"Dev1/ao0","",-0.5,0.5,DAQmx_Val_Volts,NULL));
//configure sampling clock and trigger channel
DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"",1000.0,DAQmx_Val_Rising,DAQmx_Val_ContSamps,1000));
DAQmxErrChk (DAQmxCfgDigEdgeRefTrig(taskHandle,"/Dev1/PFI0",DAQmx_Val_Rising,100));
//start task
DAQmxErrChk (DAQmxStartTask(taskHandle));
//generate waveform
DAQmxErrChk (DAQmxWriteAnalogF64(taskHandle,1000,0,10.0,DAQmx_Val_GroupByChannel,data,NULL,NULL)));
In the PCI - 6010 specifications, it is said that the PFI0 channel is a digital channel. Since my signal is analogue, is it correct to input it there?
If "no", would it be more appropriate to use this piece of code instead?
//Create task and output channel
DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
DAQmxErrChk (DAQmxCreateAOVoltageChan(taskHandle,"Dev1/ao0","",-0.5,0.5,DAQmx_Val_Volts,NULL));
//configure sampling clock and trigger channel
DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"",1000.0,DAQmx_Val_Rising,DAQmx_Val_ContSamps,1000));
DAQmxErrChk (DAQmxCfgAnlgEdgeStartTrig(taskHandle,"Dev1/ai0",DAQmx_Val_Rising,1.0));
DAQmxErrChk (DAQmxSetAnlgEdgeStartTrigHyst(taskHandle, 0.1));
//start task
DAQmxErrChk (DAQmxStartTask(taskHandle));
//generate waveform
DAQmxErrChk (DAQmxWriteAnalogF64(taskHandle,1000,0,10.0,DAQmx_Val_GroupByChannel,data,NULL,NULL)));
What is your opinion about that?
Thank you for your help.
Best regards,
João Rodrigues.

Allow boolean arrays as input for "Array Min & Max"

The Array Max & Min function is quite versatile, but for some reason it does not accept boolean arrays. This restriction make no sense at all. Since we can easily sort boolean arrays, this function should work too! It would come in handy for example if looking for the position of a single TRUE in a 2D array (search only works for 1D arrays!). Array min & max would simply return the index pair of the first TRUE found. As a workaround, we currently need to insert a "boolean to 0,1" to get the same effect. This seems unecessary.

> I have to disagree with the need to do this LabVIEW prides itself of function polymorphism, but there are these nagging little holes that give you a broken wire for no obvious reason at all. Sure there are workarounds, but the beginner programmer might construct a horrible Rube Goldberg style workaround, full of duct tape and bailing wire. We can sort boolean arrays so there is a clear order between TRUE and FALSE ---> there is a MAX and a MIN and the function should return it. Note that Array Min&Max even works for string arrays, where it outputs the lexically sorted first and last array element. (Hey, I did not know that, could be useful sometimes!). Not allowing boolean array inputs is an unnatural exception and should be fixed. A similar case is described in this suggestion (which did not get much attention either)

Does "pause trigger" have a status flag?

Hi,
I am using a BNC2110 with PCI6133 multifunction DAQ card. I am reading random analog voltage pulses on one channel for now, and using the "Pause Trigger" properties (on trigger property node) so that the read task only takes in samples from the pulses, and not samples of the baseline noise between pulses. This works ok. But is there a way of signalling when the pause trigger has actually started and stopped (at the rising and falling edges of a pulse, respectively)? I want to use these signals to index the collected data so that I know where in the data any one pulse starts and ends, and so keep all pulse data separate, but in one array.
Many thanks,
Oliver.

Hi Oliver
One thing you could do it to look for a timeout error to flag when a pause occurs. The time-out error code is -200284. If you set the timeout value to the minimum (1) you can keep checking for the timeout and set a boolean to true when a timeout occurs. So if the boolean is true you know you have a pause, if the boolean is false you know you are reading in the signal.
I have adapted the vi that you posted to do this and attached it below.
I hope this helps
Thanks

How to trigger different Initial statuses in same status profile

Hello All,
In a CHaRm flow, while creating a SDCR document from SLFN we want to make a distinction depending on the subject in SLFN. If the subject is X, then the status should (in the follow-on document SDCR)be "To be estimated" but when the subject is Y then the initial status should (in the follow-on document SDCR) be "Approved".
Since SDCR has only one status profile linked to it which has an initial status as "to be estimated". The logic is not working when we want the initial status as "Approved". Is there anyway to overide the initial status in SDCR ?
Help would be highly appreciated and rewarded.
Aba.

Hello Nirmit,
My problem is a bit different than yours.
But i can help you. You can create a Z status profile as a copy of the existing status profile. Go to transaction CRMBS02 and copy the status profile SLFN0001 to a new ZSLFN001. Once u have copied to Z status profile, u can go to Transaction types in IMG and change the status profile for SLFN Transaction type (which is used for Service Desk) with ur new status profile..
This is one way. But its recommended to copy the transaction type to a Z transaction type and assign your Z status profile to this transaction type. In the status profile, then u can maintain new statuses as u wish.
If you find this helpful, please reward some points.
Cheers

I am trying to route the trigger input on a PXI-8105 that I have in a PXI-1042 chasssis to the PXI backplane.

I have several modules in a PXI-1042 chassis that I am tring to route the same trigger to [on the PXI-Trig0 line]. I am using the VISA Map Trigger VI, but I cannot seem to get it to work without error. I am trying to use the front panel trigger from the PXI-8501 module [resource name PXI11::13::INSTR] as the souce and the PXI-Trig0 as the destination.
Since the VISA Map Trigger does not accept VISA sessions of class INSTR, how do you map a trigger from an instrument to the backplane?
Thanks.

How do you create a max/min for a series of input in labview 2010

with labview is there a way to get max/min values from a series of inputs? I want it to graph the data and keep track of what the highest and lowest values were. I am using Labview 2010

While you don't really define what you mean by a "Series of inputs", maybe Array Min&Max PrByPt might be of interest.
(For better help, attach a simplified VI that shows typical data.)
