• OK to mix 'of connection to the switch"and"close relay switch?

  Hi all

  I'm developing a test sequence using the card multiplexer 2527 to the track signals.  To configure the card, I use DAQmx switch functions.  In my application, I have a Subvi routine that imports the data from a spreadsheet Setup and run a loop for to set the configuration for each step (each iteration of the loop contains the channel for 2527 card information).  The topology is set on the first iteration, as well as the configuration of the path to the first string.

  My concern is this: I need to close the extra channels/relays without changing the topology or resetting the device.  In the first round, I use "connection to the switch" function to set the initial path, (ch0 to com0 for example).  Then in subsequent iterations of the loop, I use "Relay close switch" function to close the additional channels individually (for example k2).  In the end, when the measure is taken, both ch0 ch2 must be closed and routed to com0.  This implementation is so sure, or am I somehow to make the adjustments to the initial loop?

  I would like to test this with the hardware, but it is not yet available.

  Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer.

  Please notify.  Thank you.

  Hello GSinMN,

  It's OK to mix 'of connection to the switch"and"Close relay switch"If you understand what's happening below. "Switch Connect" connects two channels by closing a path of relay between the channels, then "Close relay switch" can be used to change the State of the individual relays. If you are not careful you can mess up your connection by activating / deactivating relays that are part of the route connecting your channels.

  "Also, I realize that I could use independent topology and configure all relays individually for each step, but I hope that my approach will be easier and safer."

  I would recommend the topology independent if you want to stick with connections to channels only. http://zone.NI.com/reference/en-XX/help/375472G-01/switch/2527_independent/

  Initial connection:

  CH0-> pcom0

  pcom0plus-> icom0plus

  pcom0minus-> icom0minus

  icom0-> com0

  In each future iteration just connect to the next to pcom0 channel (which will be indirectly connect it to com0):

  CH1-> pcom0

  CH2-> pcom0

• Sequence of a good idea?

  After the search and read a few posts from forums, I understand using the sequence is probably not the best idea?

  I wanted to get some advice on the best way to address my problem.

  What I want to do:

  I intend to use the van der Pauw method and the hall effect to experimentally determine various parameters for a small sample of semiconductors.

  Right now, it's a lot of your time to make all of the BNC connections required by the hand that in all the totals to 24 or 48 connections to make.

  To speed up the process, I want to use Labview to control a microcontroller to control transistors which controls of the Tower relays who make the required connections. At the same time after each series of necessary connections have been made, a current source controlled by Labview must provide the necessary current, a voltmeter to read voltage. A total of six different sets of four connections to perform and voltage read for all six groups. This must be done twice, but since the equipment creating the magnetic field is controlled manually, I can just run the program twice.

  Recently, I learned how to control an arduino using labview and how to control the power source and the voltmeter using labview as well.

  So here's the sequence that labview should send orders:

  Digital I/o using 6-pin on arduino

  1. initially, all pins are attached below.

  2. first pin set high, while the rest remains low. This option turns on a transistor making it the first series of connections.

  3. the current source is turned on and provides a specified amount of current to the sample.

  4 voltmeter measures the induced voltage and stores this as a double or be it in something like a table.

  5 current source turns off.

  6. second pin on arduino set high, while the rest low and steps 3 through 5 are repeated until all 6 pressure measurements were recorded.

  7. the 6 measures must be exported to excel the file or Notepad or other.

  8. the same data could be transmitted to something like a different tab in the same program to perform the calculations to find the semiconductor, parameters of the sample.

  So now my question on the best way to do these things. I was looking through labview and found what is called a sequence of flat, but according to the forums it's supposed to be frowned upon.

  My other thoughts using some kind of combination of loops/case, but I'm not sure how to structure and what should be included or excluded from the loop. Other thoughts are maybe a timed structure. Another possibility is to create 6 different vi and calling it one by one.

  So basically the program run, and once completed, I need for each measure 6 voltage, preferably displayed in both a table and saved in excel/Notepad.

  A state machine with these 8 States (and perhaps some assistance States: idle, stop, start, error, etc..).

  Basically a while loop with a case structure (one case for each State) and a State (e.g., enum) variable in a passage that. Look at the design templates provided with LabVIEW.

  (A flat sequence is too rigid for this. What happens if an error occurs in the #5 State? It has no way to go to a State of emergency. What happens if you want to stop in the Middle? What If a State fails and must be repeated.)

• Relay switching

  DUT is followed. Power is given through relay. The current control system is taking to this time delay relay is on. If the current increases up to a certain level relay must off the coast. And at the same time when the stopped program relay also change its state of not OFF. Can I use a conditional loop?

  Your explanation is a bit rough.  But I'll try to help:

  Use a While loop with a stop button.  On the inside of the loop insert your current tracking code.  Compare the current limit by using more function.  The Boolean value to a structure in the event of the wire.  If True, set the code to deactivate the relay.  If False, do nothing.  After the loop, put the code to deactivate the relay.  But you must have a wire from the while loop for the code to deactivate the relay.  You can stop button out of the loop of wire in a sequence structure flat and put the code to deactivate the relay inside the sequence.

• The relay through time and Total flow control

  Hi all

  I'm relatively new to Labview and have worked on a great program from lately, which uses a Module with my cDAQ-9178 OR relay SPST 9481 to open and close the 3 different solenoids. The program should open at a specific time and leave it open until a certain amount of flow is passed through them. I already finished the programming to record the total flow through the valves, and after many hours past the forums I found a way and changes in the code that turns on the relay based on the amount of time spent searching, however it turns on the relay and leave them on until the 'period' are filled then pass on the next round. I need to change this option further so that it lights when my "Cycle Start Time" is reached, turns off when reaching the set amount of flow for this cycle and then continues to wait until the next "Cycle Start Time" occurs.

  I imagined a way to proceed would be; by eliminating where departures from the clock a new cycle each run and just have it constantly by comparing the time of "Initial start (run)" 'Start' time sequence (when I push the start sequence and actually start to opening the relay). Then change the "delay" to 'Cycle start time' and the (> =) function to a function (=). So now, it begins after the elapsed time is equal to the start time of Cycle. Certainly, this opens the questions, because currently, at the beginning of the cycle the command of the relay begins. So I need make my comparison outside the case 'Cycle' or move the control relay in the case of 'true/false '. However, then I run the question of how to get the software to change the case once he saw to stop the relay.

  As you can see, I have about 1 million different things in my head that I played with. Advice or assistance to get me on the right track, or you know of examples would be great! My code is attached below, and I'll post a photo after this post about how I'm taking care to record the total flow. Thank you for your time and help!

  Hi M_Blaylock,

  You mentioned that you are relatively new to LabVIEW. Are you familiar with some of the debugging tools?

  http://www.NI.com/getting-started/LabVIEW-Basics/debug

  Turning on climax execution should allow you to see the data flow through your schema. Also, probing the wire just before the input case structure should allow you to see what data is actually trying this case selector. If you get unexpected data, you can probe the front steps to see source these unexpected data.

  I hope this helps and good luck with your code!

• 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

  Paul

  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

• 6.1.4 NSX upgrade to 6.2.0: DLR fails to upgrade with DHCP relay message

  Hey all, in the middle of an upgrade of non-prod to a greenfield 6.1.4 6.2. Did the Manager NSX, and follow-up of all controllers. Then after the VMware recommended upgrade sequence, I did the GSS. Then began the DLR. When you try to upgrade the DLR, I received an error message

  The "Upgrade Version" operation failed for the entity with the following error message.

  [DHCP] To enable DHCP Relay, DR instance must be created with a single connected LIF.

  

  Also, the router now displays status in the NSX edges pane: "failed to create/update edgeAssist interface for edge edge-3.» 404 not found. »

  

  So I tried erase the configuration of DHCP on the DLR with the button relay remove, no dice. Tried to redeploy, fail with the same message. Tried to force synchronization, changes in status to "impossible to force synchronization. NSX Edge edge-3 is in poor condition. Try the operation again. The DHCP configuration disappears, but the change seems never commit, because when I browse the bracing or routing section and browse to the DHCP relay page, the original configuration is still there. It is a simple DLR with no configured HA. I have attached the newspapers of DLR tech support in case there is any support curious people out there. Note, vCenter 6.0.0 2741530, ESXi 5.5 Patch 5 reissue 2718055.

  He was just going to remove the DLR and re-create it since it's a lab, but if it wasn't a lab I just want to know why it's a failure.

  After reading more carefully, I apparently missed a step in the upgrade (hosts). I suggest that whoever does the upgrade follows the upgrade guide in pubs located here: 6.2 NSX VMware vSphere Documentation Center

  • Manager of NSX upgrade to 6.2
  • Upgrade of the Cluster controller NSX to 6.2, check the status of cluster control
  • Upgrade the cluster hosts for NSX 6.2
  • 6.2 the NSX border upgrade
  • Guest Introspection to NSX 6.2 update
  • Remove the NSX data security and redeploy

  So I tried a lot of things to work myself back from that. I tried to upgrade the hosts but that didn't fly, esx-vxlan has been blocked to version 5.5.0 - 0.0.2691051. To return to a viable State in the end I had to nuke basically the GSS, logical switches, DLR, TZ, manually uninstall the NSX vibs and unsubscribe manager the NSX to vCenter in the cluster take-off of the State of "uninstall." From there, re - install the 5.5.0 - esx-vxlan 0.0.2983935 (6.2) vibs on the cluster worked OK, and I rebuilt the gateway routing and dashboard. So read before making anywhere near prod. : )

• Why E-mail stopped to relay my ISP?

  I had my server running beautifully for serval months now.  Last Friday, we noticed that some of the emails from our office did not reach their destination in a few minutes. Some would take hours and days. I could very well receive emails. We organize our company e-mail service in the House on a mac mini with OX 10.11.6 5.1.7 server. In case of problems today, I determined that the implementation of relay on the server is correct, but when I need local customers send the relay through our server it fails. If I uncheck this requirement, local customers can send very well.

  

  The requirement of relay works well until last week. Without going through this may very well at the moment, but it seems counter-intuitive. Is there a problem with the installation of relay that needs work to update or rinsed out properly?

  Now that I have turned off the outgoing 'Through ISP mail relay' switch I received a call from a person in Texas who does not work for us. He received an e-mail from his home account to our domain name.

  

  It doesn't have an e-mail account in our system. How is this possible, and is this power flowing through our mail server?

• Problem of sequence of collation for sorting on iCloud Win (Turkish sort) Contact

  I use Turkish in the names of my contacts. Turkish has the additional characters to the alphabet from A to Z.

  They are capital and small versions of gbreve (ğĞ), scedilla (Şş), o-umlaud (Oo), u-umlaud (Uu), ccedilla (Cc), capital I point (iİ) and without point-i (ıI).

  For example my name begins with capital i with a dot on top, İhsan.

  Some other examples of name are Çetin, Şamil, Umit, Omer, Bader...

  I have almost 2000 contacts in my outlook and on iCloud as synchronized as well.

  These characters have all their olaces on table Unicode.

  And there is a collation sequence Turkish governing the sort of contact names.

  In my case, I see my contacts in Microsoft Outlook (Windows) and also on the web site of iCloud.

  When I connect to www.icloud.com, I see a perfectly sorted according to collating sequence Turkish contacts list.

  But when I have the contacts list of Microsoft Outlook such as that presented by iCloud for Windows Extension, contacts are not sorted properly and starting with these special characters is listed either at the beginning or at the end.

  Problem can be comfortably attributed to iCloud extension because when I copy same 2000 + contacts in the iCloud in a native Microsoft Outlook folder contacts folder, they are sorted perfectly. Outlook can sort by the Turkish sort sequence. It is a very annoying problem that affects also search and replace too. A Z characters have a fixed position on Unicode table offset when locating the capital and reduced versions. But these extra characters do not have the same fixed offset and because of that when I'm looking for c I can't find C or vice versa.

  So sorting is OK on the website to iCloud and based on Windows native Microsoft Outlook contacts folder, but not OK in iCloud contacts file presented by iCloud extension under Windows.

• the song sequence

  Hello

  Since this update for a given title, 'CD', song or 'track' selection is no longer moves in the regular sequence, i.e.track 1 to 2 to 3 and so on. The automatic progression is random, going to randomly say 1 to 3 to 5 or 1 to 7 or 9 or 8, then sometimes back to 1, even skip a track in a title to another title, then another title. In other words totally unmanageable, without the possibility to fill in a piece of music, for example a symphony or other.

  Is there a solution to this, any ideas?

  Thank you.

  In airport utility, go to the wireless tab... from options wireless at the bottom of this page and then you will see the wireless channels

  

  

  I put the 5 GHz channel because she was using a channel in Australia which is BAD.

  Personally, I doubt that this will fix your problem... It is more likely caused by too wireless signal around you and the TC as a poor place.

  Use simple... No, apple names recommended... anyway, no spaces and pure alphanumeric characters and also pure alphanumeric passwords.

• mail server rejects emails because it does not relay. What is the relay?

  I'm trying to set up an e-mail account on my imac, iphone and the ipad. Implementation was a success on the imac and can send and receive messages to test. However, in putting in place ACCT even on phone and Tablet returns an error msg "... the recipient ' my @me.com apple" was rejected by the server because it does not relay ".". " The sender email acct server rejects email or the receiving email server rejects it? Regardless, how to fix? IOS and newer and operating system are installed on all devices.

  Relay, this is how mail servers send messages between them. You are not a mail server, you will need to login with the appropriate credentials. The configuration for sending mail is bad for the account that you are using. These settings are found under SMTP, the main server at the bottom of the account settings. The automatic configuration of iOS is perhaps not good for the server. Since he works on the iMac, you can use it as a guide. Look especially for the SSL port number required and the type of authentication (password, etc.).
