• Sending a pulse to pin using an output switch

  Hello

  This is my first program in labview.

  I want to use a while loop continually between data for the acquisition of data that displays on an oscilloscope. The output signal must be controlled by a switch (0 when the switch is open) and 1 when the button is pressed.

  I put a toggle switch in the while loop and connected the output to data acquisition Manager, but he demonstrated a connection error.

  Source type is Boolean.

  Type of sink is 64-bit real.

  So, how can I convert data from the switch so that it gets feeding the DAQ output?

  Thank you.

  When the switch is off, he sends a zero, when turned on, it sends a 1.

  You will need to keep DAQmx inside the while loop probably you can use the structure of the event to do this. Also even if you set up the digital output you must select channel instead of multiples (unless you really have multiple channels) then you can connect the switch directly to it.

• Output switching PWM of routing

  Hello

  I want to put in place a control loop with 2 PWM signals that would be connected to 2 inputs of a H-bridge drive an electric motor. So we PWM would make the engine go to the right, the other to the left. (similar to a controller of hot/cold)

  Two independent counters are available (PXI6602).

  When I want to change the meaning, I have to turn off the signal PWM one and turn on the other. However, duty cycle 0,0 is not allowed. I could stop the one / start another task and vice versa, but this seems very heavy.

  Is it possible to direct the output of counter (i.e. the PWM signal) through a digital line? In this way, I could keep the PWM 'dormant' clocked at minimum cyclical report, while the 'active' PWM does its job and only inhibit the respective output digital line zero - ING it.

  Thank you for your attention.

• 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.

• 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.

  GSinMN

  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

• How to synchronize the start of IT and relaxation the Scan list (DAQmx Switch)

  Hello

  I want to measure samples of N to the AI0 of Council NI PXI 4461. The measurement starts on a rising edge of a digital triggering provided to the PFI0 of the same Board. The measure is configured with samples of N/2 pretrigged. So far, everything is under control...

  Using an NI PXI 2567 Board, the signal applied at the entrance the 4461 (AI0) switches between a V2 and V1 signal. I would like to synchronize the switch between the two signals with the trigger signal applied to the input of the PFI0 Governing Council 4461. In order to obtain samples of N/2 of V1 and V2 samples N/2. Synchronization of 1 to 5 ms would suffice!

  My question is how to synchronize the start of acquisition of AI pretrigged of 4461 with the switch control given by the Council of 2567?

  Thank you in advance for your help...

  PS: the configuration of the system is:

  -LabView 8.5

  -Chassis PXI-1044

  PXI-4461 on slot 2

  Module 4-slot PXI-2567

  Hi Frederic,.

  I came back to this recently and used the following examples to run the desired synchronization.

  PXI-4461: Acq & graph tension-Int Clk - dig Start & Ref .vi

  Samples per channel = 1000

  Rate (Hz) = 10000.00

  Start the trigger Source = / [name of the instrument DAQmx] / PXI_Trig0

  Onboard start = fall

  Reference Source Trigger = DAQmx Device Name] / PXI_Trig0

  Reference edge = fall

  Trigger samples = Variable (100, 500, 900)

  PXI-2567: Switch Scaning-SW Trigger.vi

  Advance the output terminal full = / [name of the instrument DAQmx] / PXI_Trig0

  Scan list = / [name of the instrument DAQmx] / ch0-> com0.

  Scan list = / [name of the instrument DAQmx] / ch1-> com1;

  Hardware configuration:

  The PXI-2567 module controls an external relay that switches between the voltage of 5 V on ch0 and ch1 0 V.

  The PXI-4461 connects to the COM of the external relay and therefore reads 5V when ch0 is connected; 0 v when ch1 is connected.

  Procedure: The above examples are used in the following procedure.

  1. run the PXI-4461 VI.  A start trigger (falling edge) is necessary to start collecting samples before firing.

  2. launch the module, PXI - 2567 VI.  When ch0 is initially (and immediately) on com0, a trigger is sent to PXI_Trig0.  The PXI-4461 will begin to acquire samples before firing.

  3. - click on the "Connect to the next" button on the front of the PXI - 2567 VI module.  This sends a trigger to entry software for the PXI-2567 module and the transitions of the scan for ch1-> com1 list.  Once the PXI-2567 module remains (debounced), advanced complete relaxation is sent on PXI_Trig0 for the PXI-4461.  The PXI-4461 will begin to acquire samples after outbreak.

  Note: Instead of the trigger of the software entry, an external input trigger can be used (e.g. PXI_Trig1).

  Results:

  > Before instant release of samples = 100

  Delay is caused by the time of actuation of external relay.

  

  > Before instant release of samples = 500

  Delay is caused by the time of actuation of external relay.

  

  > Before instant release of samples = 900

  Delay is caused by the time of actuation of external relay.

  

  I hope that the attached screws and the explanation above helps you and/or other customers who have this problem.

• PowerConnect 6200 series interoperability with 3Com Switch 5500.

  Hi all

  We offer to our customer Dell PowerConnect 6224 and 6248 as they are expanding their network.

  Their existing network is 3Com Switch 5500 and the main switch is 5500G - EI. Of course, on their network, they have mutiple VLAN and switch 5500G - EI core will make the VIRTUAL LAN routing.

  I would like to know, is it questions about interoperability between 3Com Switch 5500 and Dell PowerConnect 6200 Series, especially on the VLAN routing?

  Know your opinion.

  Thank you and best regards,

  Syed.

  I'm not aware of any questions that you would see with the use of these switches together. On switches 62xx you set them VLAN, and then set the connection of 3Com in general or Trunk mode, allowing the VLANS on the connection.

  Create a VLAN

  Console (config) # vlan database

  VLAN console(config-VLAN) # 2

  VLAN console(config-VLAN) # 3

  VLAN console(config-VLAN) # 4

  output console(config-VLAN) #.

  Configure the interface in Trunk mode and allow for VLAN through it.

  console switchport mode trunk #.

  console # permit trunk switchport vlan add 2,3,4 tag

  You may need to set a static route on the 62xx switch so the traffic on the next hop.

  Console (config) # ip route 172.16.0.0 255.255.0.0 10.0.0.2

  Here are a few good white papers to look over. Not all of them concern the 62xx switch, but the information is always good.

  Each Vlan cannot communicate with the switch, I think they have a problem in my configuration of vlan / port, can you help me.

  Hi, Thibaud,.

  Thank you for the purchase of the ESW switches.

  Just out of curiosity, you are using the latest firmware on your version of switch ESW 2.1.19

  But of course, you seem like you have a great understanding of Tagged and VLAN no tagged of you ad description... great stuff.

  I just tried your configuration, I can communicate between ESW540 - 24 p-switch and a SF300 - 48p.

  Sorry, I don't have two switches handy ESW. But it doesn't matter. Standards based Ethernet is I hope that some standards based on ethernet

  My configuration of vlan below for my ESW540 - 24 p and it works very well.

  I plugged just ports of the switch 24 between the two switches together, that's why the 24 port is labeled in each of the screenshots below.

  I really really doubt you would have a problem, unless there is something fundimental or basic you did for example do not save the configuration running on the boot configuration.  Obviously do not save the configuration before a power down will kill the configuration.

  (saved your configuration in each switch)

  

  

  Here is a copy of a part of my switch running configuration, which were a result of me playing with the ESW configuration utility.

  (Note that my switch has all Gigabit ethernet ports ;)

  As I said at the beginning on the $line0, lin1and line2, they serve to control the relay in my circuit. 10ms could be controlled with the OS clock. Pulse of line3 series is used for IGBT gate signals, which is the critical moment. I want to use the clock machine to accurately control line 3 and synchronize at the same time the pulse with analog inputs from an another two NI9206 modules in the same cDAQ chassis.

  I just want to know more on the digital line demand signal relay output and a correlation between the line of analog input-synchronized finished pulse output. Waveform diagram is locked.

• Switch Connectivity

  Hey Cisco experts!

  I have a small question, I'm sure you can answer for me. I have installation of the Israeli army for the clients that I questioned how they are physically connected. Connection to the MDF is ok because they use their ports of 10 GB on fiber optics. The question I have is if there are multiple switches in the Israeli army should they be connected to each other using their 10 GB ports from A to B and C and then also to connecting A to C on switch ports? I think it's can cause a loop but wanted expert advice.

  Thank you

  Hello

  Yes, when you have multiple MDF switches, connect together to provide redundancy of the network.  Of course if you connect to layer-2 switches together, you must run stp or use some other technologies like stack to make it look all MDF has a switch.  There are also VSS for the 6500 that offer the same advantages as the stacking on the 3750 series.  In this way, your don't have to use STP.

• Help with redundant switches

  Can somone tell me if it is necessary to join two switches together during the definition of redundant paths and so why is this need to be?

  To give an example, I have a box of ESXi 3.5 with 2 uplinks were team together for iSCSI software storage. On this team, I have a cable going to a switch and another cable from another switch. My san also has the same configuration for the grouping.

  The switches must be connected togther and if so why?

  Typical connecting two switches together aims to make them behave like a single large switch and increase redundancy.

• Connect a PCI-6521 and a PCI-4065 DMM

  Hello

  I would like to know if I can use that digital relay is issued by a PCI-6521 to switch between the 4 lines in which I have to measure resistance using a PCI-4065 DMM.

  I´d would like to know if West any question if I log out of the PCI-6521 together four terminals (to GND) and then I connect the other 4 sides of each output at each of the points where I need to measure the resistance. So when I measure the R1 resistance, for example I have activate the respective relay output and I disable all other 3 exits. And then I read the resistance with the PCI-4065. And so now... with the other 3 resistances. I´d would like to know if West any connection problem of the PCI-6521 with the entry of the PCI-4065 DMM outputs.

  Thank you!

  Hi MariMS;

  You can use the configuration that you explain, but a 4-wire or 2-wire configurations are recommended depending on the application, for example, if the resistance you meassuring is greater than 100 kOhms, you can use a configuration 2 son, but if it is lower, you must use configuration 4 sons. The following document has a more detailed explanation about them.
