calendar intermodules cDAQ

Hello

I use a 9178, CompactDAQ, with a 9237 (strain) and 9411 (HS digital) module (s).

The deformation module has two attached load cells and the 9411 as a rotary button configured with X 4 entry quadature.

I created two tasks, one with two load cells and the other with the position of the wheel. I put the sampling frequency of 10 kHz and the two tasks are timed off the coast of the analog sample clock.

My question is, how do I determine what time it is (if any) between the 9237 readings and the position of the encoder? I constantly both running in a while loop and I'm just collecting data as if they were the rule.

How can I determine the delay specified? Playback controls are both in the same loop, but they run "parallel", so I don't know if we run first. I have it configured to read 100 reads per loop iteration, and I add to a graph. I'm trying to understand if there is any delay or offset compared with the reading of the strain to the position of the encoder to read.

I hope it's clear.

Thank you

Jeff

Hi Jeff,

It would really be a delay specified with what you have. However, there is a delay of filter you would have to explain since you use a 9237. The links below tell more and how you can adjust the delay of the filter:

  • synchronize 2 cDAQ-9215 modules on the cDAQ-9174

    Hello

    We collect 8 channels of the AI of the comments about 32KS/s, but they must be synchronized with precision. We intend to use 2 CDAQ-9215 modules mounted on a CDAQ-9174 chassis.  This system will do the job? And what kind of calendar and clock configuration should I use to improve the precision of the synchronization.

    Thank you.

    Hello

    I'm sorry I didn't know not the 9215 was a simultaneous module.  Instead of the S series card, you should be good to go with a 9174 and 2 9215 modules. If you use the same DAQmx task to run on all 8 channels acquisition they share all the same timing engine and snack at the same time.

  • cDAQ AO to I

    Hey everybody,

    Currently, I'm reading in 4 channels of I and 1 AO output signal. For my application, the calendar of area of OCCUPANCY for the AI is of importance. To be sure, I would record the AO output signal. Is it possible to record this signal AO somehow internally with to make a loop of material?

    I use a cDAQ-9178 with a 9215 and a module 9263 in it for this purpose.

    George

    Hi George,.

    If you have an AO you can´t use as HAVE at the same time.

    In the data example based in LV basic find an example of a voltage - output continues. (help--> find examples--> HW Input and Output--> DAQmx--> analog output)

    You can see, that the signal of the AO is shown in a graph it.

    Instead of the chart, you can also use a table or something else.

    Hope this has been helpful.

  • cDAQ-9184 AI DO

    Community of hell,

    I'm working on a chassis OR cDAQ-9184-one module (NI 9474) and two modules of it HAVE (NI 9215).

    The task is to acquire analog measurement and generate a pulse train to trigger a Laser sensor. Please find attached my simple diagram.

    The challenge here is to know how to sync the and GOT them. As a newbie in this area, I get several questions as follows:

    1. for synchronization multifunction, I need route my output internal counter to the task of AI as a sample clock. In NI MAX I can find this source in the advanced calendar section. However, in Labview, this CtrxInternalOutput is not available in the DAQmx Timing.vi.  Do you have an idea what could be the problem?

    2. during the measurement, I got 6590 HAVE measures and 6699 laser that are triggered by the pulse train with a sampling frequency of 500 Hz. It seems that we do not get the same amount of HAVE and. What could be the problem?

    3. information on this synchronization, in my opinion, we must configure the same sampling rate, the same same sample clock and HAVE & acquisition start together. Am I wrong? The difference in the number of samples is possible due to IT & do not stop at the same time, when I press stop in Labview?

    Thanks for your help.

    -sparkle

    1. the "Advanced" are hidden by default.

    2. There are two issues:

    i. you must start the task I face the task of meter output while he is in time for the first edge of clock.

    II. to make sure that read you the same number of samples in the form of impulses generated, you must stop the task of output of the meter and make sure you read back all the samples that were in the FIFO of AI.

  • Calendar Apple App Bug frozen works only with iOS 10 update grrr

    Since I updated to iOS 10 (more more later than 10.2, etc.), everything was not too bad except THE APPLE CALENDAR app, its deiving me crazy when I click on the app it's like it freezes and past shift x 50 mode still something to do with the calendar app will cause either a frozen or a black screen or white and then crashed ack to main menu. Sometimes it will allow me to create but will be trolling with typing and finally crashed or not even save it... Please HELP I am sure what else to do, I tried to download google calendar and which seemed to have something of bug he loves too then something happens. And I tried to delete it and download it again, / force delivery, nothing has changed

    Hi there calsparks!

    Thank you for bringing your question on the calendar of freezing and trolling since the update to iOS 10 on your iPhone for Apple Support communities.  I rely on the calendar to keep my life organized, so I'm happy to help you resolve this issue today.

    Looks like you did a few good troubleshooting by force to leave the app, force to restart the iPhone and deleting and reinstalling the application calendar.  At this stage my next recommendation would be to backup your iPhone, then erase and restore your iPhone as a new device, then test calendar to see if it behaves correctly, and then restore your backup.

  • How to disable alerts from travel time calendar

    From iOS 10, I get calendar alerts, not 5 minutes before my meeting (which is what I said), but rather these travel alerts in time talk about traffic conditions and if I leave now, I'll make my meeting... or something to that effect.  Is it possible to disable these and have just alerts timed static normal that I specify.

    And besides, all my calendar events have time to travel the value 'None '.

    Thank you.

    Hello JupiterOne,

    Thanks for this info and choosing the communities Support from Apple. I know how to turn off this alert leave time is important to you! The good news is that these steps will be useful in solving your problem with this alert calendar events, you can go to settings > calendar > default alert time and disable the time alert off. This will transform this AutoFix to this alert feature.

  • After the installation of Sierra, calendar does not work

    After installation of Sierra, when you open the calendar on my Mac, missing entries and the screen is frozen with the comment 'Moving calendars to the server account.' I signed that I the cloud to see if it would help, but I still have this problem.

    Hello and welcome to Apple support communities, Stanley Star.

    If I understand your message to the right, at the opening of the calendars for the first time after upgrading to Mac OS Sierra, you are missing calendar events and the app is frozen with a message saying "moving to Server account schedules. Calendars, this is one of my apps used on my Mac, so I certainly understand the importance of having the opening and operating as usual. I'm happy to help you to turn it on again!

    Icloud and a signature was an excellent step to try. Here are the steps I recommend to do next:

    1. Check that the date and time are correct in your Mac by following the steps in macOS Sierra: set the date and time on your Mac.
    2. Close the present calendars on your Mac. If you are also reminders, close that as well as reminders and schedules work together. If the calendars close normally, will not force close it by clicking the  in the upper left corner of your screen, select force to close, select the calendars in the list of open applications, and then click the button close Force.
    3. Go to System Preferences > iCloud and uncheck the boxes next to the calendars and reminders.
    4. Restart your Mac.
    5. A times restarted, open again your calendar application, select "Calendar" in the Apple menu bar in the left corner of your screen, select "Add an account", choose iCloud and sign in with your Apple and the password.
    6. Give your calendar some time to sync and charge all your data. Once it is loaded successfully, and you can see all your events, open the reminders and do the same steps for signing in iCloud there are also well.

    Thank you for using communities of Apple Support.

    Take care.

  • How to invite people to an event calendar with the new iOS 10?

    Before I updated to iOS of 10, I was able to create a calendar event with the apple iPhone built-in calendar and there is an option to 'invite' contacts him so they could add to their calendar. I can't find this option now after the new update. Where and how can I do this?

    Invite others to an event. You can invite people to an event, even if you're not the one who, on demand with Exchange and some other servers. Press an event, press on modify, then on the guests. Type the names, or tap to select the people to contact. If you don't want to be notified when someone refuses a meeting, go to settings > calendar, then disable view guest declines.

  • the iOS 10 not displaying calendar widget is not the events

    After the update to iOS 10.0.2, the calendar available on the lock screen widget does not always display the events. Nor the duration of the event or the event name appears, but a white widget with calendar color bar can be seen.

    This is not always the case, but very often. For ex, if you open the calendar application, then check this widget, event, but after that you lock the screen and check again, it would disappear.

    Hello jyothishureth,

    Thank you for using communities of Apple Support. It is my understanding from your iPhone Calendar widget still shows no events. I use my daily calendar to keep me organized. I can understand your concern. I'm happy to help you.

    If you haven't done so already, I recommend that you restart the phone. This can solve many unexpected behaviours. Follow the steps below:

    1. Press and hold the sleep/wake button until the Red slider appears.
    2. Drag the slider to turn off your device completely off.
    3. Once the device turns off, press and hold the sleep/wake button again until you see the Apple logo

    Restart your iPhone, iPad or iPod touch

    If the problem persists, try to remove the widget and adding it back on. Use the following steps:

    1. Right above the home, lock screen or Notification Centerscreen.
    2. Scroll down and tap on change.
    3. To add a Widget, press on . To remove a Widget, press on . To reorder your Widgets, touch and hold next to the apps and drag the in the desired order.
    4. Finally, tap done.

    Use Widgets on your iPhone, iPad and iPod touch

  • Calendar is the name of the month showing

    This is a new, just started my laptop this morning and the menu bar showed M10 5 sea, which is also how it looks in the calendar. All other months are the same (M01, M02, etc.).

    Tried resetting the PRAM, but can't see any prefs calendar that I needed trash as the only one is the synchronization agent.

    Anyway to get my laptop to remember what it October again? Do not know if it is connected but it also completely forgotten that I have my trackpad tap to click and three fingers to drag, and I put DND in Notifications.

    Hi Ben Collier.

    Looks like you're some problems with your Mac, specifying the digital number for the month, instead of the names of the months themselves. Also, you have some problems with the trackpad preferences and do not disturb for notifications. I can see how you would like to get this all resolved. We'll see what we can do.

    I would like to first of all, you have set the trackpad preferences and do not disturb the notifications as you want, then start up the Mac in safe mode.

    OS X El Capitan: Notifications preferences

    OS X El Capitan: start in safe mode

    Once you're in safe mode, please try to see if the names of the months are returned and that the trackpad still works as expected. If the names of the months back, please restart the Mac and open the calendar application and then check to make sure that the problem is solved. If issues are not resolved in safe mode, please create a test user and verify. This will help us to determine if the questions are the scale of the system or a specific user.

    How to test a question in another account on your Mac.

    Thank you for using communities Support from Apple. Have a good night!

  • iCloud suddenly ask for password for public calendar shared

    I'm on a mac, my Windows 10/Thunderbird woman. I have a public calendar to which it subscribes. When I upgraded to Sierra, suddenly iCloud requires a user name and password for this public calendar. The message we receive is:

    A user name and password are requested by https://p08-calendarws.icloud.com. The site says: "MMCalDav."

    My name of user and password does not work. The calendar is certainly defined as public, marked like this on my mac and iPad. What can I do so that she can see my calendar?

  • Calendar alerts stopped working in IOS 10

    I can't understand why, but calendar alerts do not go to sea. Very frustrating. I searched around online, made sure that I am not on do not disturb, etc.. Anyone else having this? I think it's a problem on my iPad, since alerts on this device (annoying) turns off at the same time. Thanks for any input.

    I noticed on my iPhone and iPad about 10% or more alerts will never happen. They do not sound that they appear on the screen "info". They all work correctly on my Mac.

    Input events calendar I have on my Mac don't sync my iPhone or Apple Watch.  Events calendar on iPhone synch to iMac.  in iCloud preference, I've marked contacts, calendars and notes.  All the work schedules.  Any suggestions?

    Option 1) update your calendars and reminders of the app of calendars:

    Open the calendar application.

    Choose View > refresh calendars.

    Try option 2) remove the account in calendar > Preferences > accounts.

    Now add back.

    Option 3) if it still fails to work, try to test in the comments or new user.

  • Import emails .ics calendar events

    I recently updated my 5 c to 10 IOS iPhone and I can't import all events in a calendar .ics file into the standard calendar from an email app.

    Previously in older IOS, the method was:

    1. open email with the .ics file.

    2. tap on the file in .ics to display a list of events.

    3. scroll to the bottom of events and press 'Add all' and then select the calendar to which events are to be added.

    Nothing is more a ' add all ' button. I tried to add events one at a time, but appears not to half of the working time.

    I met the same problem.  I tested this by creating a file ICS w / calendar (version 8) on my Mac OS X (el capitan 10.11.6) then sent me.

    Using the default e-mail program, I can see the file but cannot add them both.  Is there another way, we are supposed to do now?
