Two control relays

• Control relay with Boolean switch using DAQ assistant 9481 - problems

  Sorry for what may be a stupid question but I'm stuck in quicksand.

  I use a relay module 9481 and have two external relays connected lines 0 and 1.

  When I create a digital output 0 line by line, I can run the test inside the express and activate the relay and turn off without problem.

  The generated block DAQ expressed expects a Boolean input of 1 d. (See attached photo).

  I want to connect a Boolean switch relay line disk 0. You can connect live not because the switch is Boolean and the input is Boolean 1 d - I'm a conversation in the pict.

  All plumbing lines display results, the relay never active.

  Any bunch would be greatly appreciated! Thank you

  

  Mr._Mechanical,

  Welcome to the Forums of switch OR this forum is generally intended for products OR-SWITCH [such as the NI PXI-25xx & NI SCXI-11xx], I think I know the answer to your question.

  I think the reason why it's a failure is the conversion you make generates a table of 16 Boolean [as the 'boolean to (0,1)' function creates a data I16 type] with your data more false data points 15.

  

  When you try to control the relay, he sees 16 datapoints are you Commander to a single port [channel] and so error out.

  

  My suggestion would be to use normal DAQmx digital output screw [with, he set up as ' Digital > single channel > single sample > Boolean (1 line) "] rather than the DAQ assistant.

  If you use the daq assistant, simply by using the function 'Building the table' will transform your simple Boolean data point in a Boolean array containing a single element.

  

  While the DAQ assistant is very easy to use, I recommend that you use the DAQ assistant, because this reduces the features and increases the execution time.

• How to bind together two controls

  Hi all! I am now trying to create a range using two digital controls, but I don't know how to connect these two controls set in the block diagram.

  I need to create this scenario, this range (fixed by these controls) to exceed a number fluctuating (temperature) until the fan is running; kind of like a control 1 "AND" 2 control must be above this temperature, the other conditions are ignored.

  Thanks in advance for the help!

  

  
  

• Reminders of two controls "at the time"

  I need a little help with most of the user interface callbacks and threads.

  Here's the scenario: there are two controls

  1. digital control with callback for EVENT_VAL_CHANGED

  2. button with callback for EVENT_COMMIT

  RunUserInterface() is called once at the beginning of the program. The user enters a value in the control digital with the keyboard (some numbers), and then they click on the button.

  This triggers the following events:

  (Digital) EVENT_VAL_CHANGED--> digital reminder works

  EVENT_COMMIT (digital)

  EVENT_LEFT_CLICK (button)

  EVENT_LEFT_CLICK_UP (button)

  EVENT_COMMIT (button)--> button callback runs

  EVENT_LOST_FOCUS (numeric (?))

  EVENT_GOT_FOCUS (button)

  The recall button parts can run before the digital Encore ends?

  Thank you!

  To answer question of Ian, Yes, all UI events are sent to the thread that owns the group. Here's the relevant help topic of the CVI.

• 6008 daq digital outputs to control relays

  Hi all, I'm looking to help create a VI to send out digital to a daq 6008 to control relays. What I'm trying to do is when you press start and a condition is met send a digital output to control a relay for 30 seconds or so to take a measured voltage to be taken an analog voltage. After 30 seconds, I want the first relay to switch off and the next relay lights for the same amount of time. I want to continue this sequence to 7 readings, blood for every step and send the data to an excel file. I know it's basic stuff, but my experience with labview is limited! Any help would be greatly appreciated.

  Thank you

  Hi Paul,.

  I looked on your problem this afternoon and I agree completely Fan Ravens that the state machine is in fact the most appropriate architecture for such a task of data acquisition. A state machine architecture is one of the most commonly used in LabVIEW design patterns and is especially suitable for any program where you have clearly defined the steps that can be represented by the States and rules for the transition between these States.

  There is a model of Machine of State Standard contained in LabVIEW which should give you an idea of the underlying architecture and is a good starting point. To give you a better idea of how this architecture can be applied to a data acquisition task, I would recommend that you look at This example. Although States will be slightly different in your case, this should provide you with a good understanding of how you can architect such a request.

  I hope this helps.

  Best regards

• How to bind two controls?

  Hello

  I'm trying to bind together two controls, a slider and a digital, so that if I change the value of a control, the other will also show the new value.

  Anyone know how to do this? Is it still possible?

  Thank you for your help

  

  Right-click on your cursor.  Go to visible items-> digital display in the menu.

• How to add two controls on the same form datagrid? I get the error message...

  Hello

  I have to add two controls on the same page datagrid. When I try to drag an another DataGrid in the components window, it says "an element with that name already exists in the library."

  How can I add multiple controls on the same page datagrid?

  Kind regards.

  _data2 = new XML (event.target.data2);

  should be

  _data2 = new XML (event.target.data);

  (actually, it's better if it was

  _data2 = XML (event.target.data);

• Two controls data, user interface

  andrejusb.blogspot.com/2012_08_01_archive.html

  In the link above, andrejus explained how to use a single UI for two human tasks.

  I have a similar case to use with slightly different. I have to use the same user interface with or the other of the two controls different data available under certain conditions.

  In other words, the UI remains same components will, but data will be filled with one of the controls two data.

  Hope that I presented the use case clearly

  Adaptive links (https://blogs.oracle.com/groundside/entry/towards_ultra_reusability_for_adf) should work for your use case.

• can anyone tell how to compare two documents with two controlled with the same mouse pointers

  can anyone tell how to compare two documents with two controlled with the same mouse pointers?

  Windows and OS X can only display a mouse pointer - it is created by the operating system, not the application.

• set the duration for the nor 6501 to control relay

  Hi all

  I made great progress thanks to your help. Now, I know how to control the relay using NI 6501.

  Furthermore, I try to put in place a period of time (after two hours) and leave-6501 OR turn on the relay.

  What kind of example I can refer to?

  When pressure data are weak to 1mtorr, then turn on the relay is another control.

  If there are some I can refer to similar examples, it will be useful for me to programming

  Thank you

  
  

• The task bar has two control panel icons

  The task bar has two icons in Control Panel. When I added my office to the two taskbar Control Panel icons apperded. (I have the taskbar right-click, then toolbars and selected Desktop). I can delete the second icon in Control Panel, but it returns to the restart. I found as subjects during a Google search. Someone else has the same double icons? Is there a fix to Windows? I am running Windows 7 on the new system.

  That did not work.

  It does not - it did for me when I go from 7 to 8 and then 8 to 8.1

  You MUST delete a registry key.

  Create a file "deleteCPIcon.reg" with:

  Windows Registry Editor Version 5.00  [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace\{5399E694-6CE5-4D6C-8FCE-1D8870FDCBA0}] 

  Run the file

  Voila!

• Control the event with two controls

  Here's what I have.

  I have two separate loops of time. Inside of each timed loop, I have a structure of the event. Each structure is the trigger by pressing a button each. It works very well.

  However, I would like to add a third button that runs the two structures of the event. I want to do this without creating additional events in each structure. Is it possible to somehow this third button wire to the other two and to trigger both based on the action of the third? I have problems it works.

  Thank you

• 4250 - SX: use two control ports supported or not?

  4250 SX sensor, I have two monitor ports.

  -Is it possible to use both at the same time?

  -Are there restrictions?

  -Is it supported by Cisco?

  Thank you very much

  Kurt

  -Is it possible to use both at the same time?

  Yes

  -Are there restrictions?

  The total bandwidth of 2 interfaces must add in the performance audit.

  The IDS 4250 SX is assessed to 500Mbps so if you receive 350Mbps the map of SX, then only plan on sending 150mbps for TX standard sniffing port.

  -Is it supported by Cisco?

  Yes

  SIDE NOTE:

  Do not confuse the IDS 4250 SX with the IDS 4250 XL. The SX has a single card PCI SX, while the XL is a double SX PCI card with hardware acceleration built into the card.

  With the XL both SX ports can be used for monitoring (but the standard TX port on the motherboard cannot).

  Combined traffic both SX ports must not exceed the return of the IDS 4250 XL (1 Gbps).

  Sniff two XL SX ports is supported by Cisco.

• connect the two controls of VCS to Call Manager, unity and IM/P by AXL for migration

  All,

  I'm migrating from physical to VM for my VCS-C/E. can I connect ' my existing physical VCS both my new virtual machines to CUCM, unity, IM/P by AXL at the same time? or should it be done at the during the downtime of the migration?

  The new virtual machines are not ready yet... always set up the production.

  Thank you

  RB

  You can integrate physics VCS C/E with CUCM, CUC, IMP from now. Once you are about to migrate to virtual VCS C/E, you can integrate virtualized VCS C/E with CUCM, CUC and IMP and shut down physics VCS C/E.

• I want to order two relays, but Labview says that I have something wrong with my VI

  Of the image, I have 2 control relays, they are the two toggle switch type, I want to control at the same time, but fail to do so.

  I already have digital > channels > single sample 1 > Boolean (1 line per channel) and before I run it, I choose the channel 0 and 1 in the front panel

  When I run it, the program does not give error, however, I use a voltmeter to test the voltage on ports 0 and 1, they are 5V and stabilize... which does not correspond to the VI I write

  After you click stop, Labivew said:

  read name or write operation failed because the number of rows in the data of a string is not the lines in the channel.

  If you use the digital waveform data type, make sure that the number of lines in the digital waveforms is the number of lines in the channel. If you are using Boolean data, make sure that the dimension of the array for the rows of the data is the number of lines in the channel.

  Number of lines in the channel: 8
  Number of rows in the data : 1

  Task name: _unnamedTask<4>

   

  
  What is the problem with my VI? Thank you

  He doesn't seem to like the layout of the table 1 d Boolean.  It is not sensible.

  But I found a way so that it will run without errors.  I don't know without having a real DAQ hardware whether outputs will be correct.

  1. change all DAQmx wrote on the Board of Boolean 2D, (N lines per channel).  If Digital > multiple channels > sample > Boolean 2D.

  2. change all the raster constants to add a dimension turning them into 2D Boolean tables.

  Now, it will run without error.  But if the output is correct or not, you need to test.

  You said you want to control the relay.  I don't know what kind of relay that you have, or is that your DAQ hardware, but take keeps most of the DAQ cards do not provide enough current to directly drive a relay.
