• Delta PLC with single-phase inverter

  Hi all
  I have Delta DVP 20EXPLC. In this machine, we can generate output pulsed Y0 and Y1. I wish to make the single-phase inverter with the help of this dry vegetables. Now, I use four MOSFET that will operate the switches to reverse operations. Fundamental reversal operation is right there pair of transistors MOSFET only should be remnants or OFF. The problem for me is, when I give the pulse of the controller, the pulses of the MOSFET 4 are the same, it cannot work with the above format. So, I have no inverse sine.

  I hope you understand my condition. If it isn't enough, I'm willing to explain deep depending on the response. Please help me with this problem.

  OR if the opportunities are there to control the VI MOSFETs...?

  Hello

  Your application this MOSFET control requires only the digital output that can be transmitted using any protocol of industrial communication.

  I checked the information on Delta DVP EX and found it supports these protocols: Communication port: integrated RS-232 and RS-485, MODBUS ASCII-compatible / communication RTU pro....

  LabVIEW supports all the of them. You can find examples for the first two in LabVIEW help - find examples...

  You can download Modbus support since the product page of NOR.

• Wiring of the AC source single-phase NI 9225

  Hi all

  How can I wire an AC single-phase my point of wall to the module OR 9225.  Agrees that if I connect LIVE wire wire HAVE + and I - NEUTRAL wire?

  Thank you

  Ajay.

  Yes, just do not exceed the 300 Vrms as stated in the Manual:

  http://www.NI.com/PDF/manuals/374707c.PDF

  And make sure that the power is off when it you wire!

• Can I use a NOR-9244 for measuring single-phase AC 2-wire 480V?

  As the 9244 module is rated for a maximum of 400 v L - N and L - L 800V, to measure 480V, I would need to connect to AI0 AI1 and let the neutral entry floating. Manual outlines all single phase measures referred to the input neutral and has some instructions on the conversion of L - N L - L measures, but it is expressed not bad so I don't know if it tells me that I can directly measure the voltage through AI0 AI1, or not.

  Can anyone confirm that I can make measurements with 9244 cable in this configuration, until I drop the $$$ to buy it?

  Hello MStewart,

  A distinction must be made between Vpk and Vrms.

  @GerdW is correct that the input device is ~ 1000Vpk (997.5Vpk). However, this translates into ~352.6 Vrms

  The side of 800 Vrms for line (L - L) measures is for multiphase applications.

  As you take a single-phase measure, you would use an AIx-neutral (L - N) connection.

  The diagram for this is detailed in figure 12 on page 25 of the Manual:

  <>http://www.NI.com/PDF/manuals/376131b.PDF >

  So to measure above 400Vrms on this unit, you will need to use a power supply external to resign from the tension, as mentioned in the white paper in (specifically the section of voltage):

  <>http://www.NI.com/white-paper/8198/en/ >

  In summary the 9244 cannot directly measure 480Vrms.  You can set before the signal to less than or equal to 400Vrms

  I hope this helps to clarify your question!

  See you soon,.

• Select multiple channels for a single task - control and shift keys do not work

  Hello

  Following the advice of several other positions, I try to choose several physical channels in the drop-down list so that I can then use the function "unflatten channel channel" later. It seems that if I hold this key is pressed or cntrl, I should be able to select multiple channels in the list, however, this does not work for me. I tried to go in the "navigation key" property for the control channel to task, but there not all listed associations. Someone else has encountered this and found a solution?  I previously around that by declaring several channels by a colon (for example, ai1:3), but it does not work for the unflatten function.

  Thank you

  Claire.

  If I understand correctly, I think that you need to do is use a task property DAQmx. Try to use the channels property to get an array of strings.

  It seems that the problem of database. I found similar in 'Doc ID 1638989.1'.

  In your journal, I see that it comes in the catalogue (to the oracle.iam.catalog.repository.DBRepository.updateCatalogItems(DBRepository.java:4053)).

  The solution was the following: "apply the patch database #17501296 to the 11.2.0.4 database version.

• If I config ISAKMP (phase 1) duration shorter than the life expectancy of IPsec (phase 2). What's going to happen.

  Since I couldn't find any document from Cisco (Cisco produces only that, the longer life ISAKMP, safer) of the directive.

  I was wondering if I config life ISAKMP (phase 1) shorter than the life expectancy of IPsec (phase 2). What happens when I still have the traffic through the VPN, the ISAKMP his timeout reachs tunnel. Phase 2 would also got laid off, and turn all the negotiation of Phase 1 VPN again?

  Any help will be appreciated.

  Angela:

  We probably need to consider the context of your use of the term "session".

  If you had to define an ACL crypto that consisted of a single access control entry (example: 192.168.1.0 ip allow 0.0.0.255 192.168.2.0 0.0.0.255), which would be generally * lead to the creation of an ISAKMP security association unique and two IPSec security associations. Lets call it a "session encryption.

  As you said, the implementation of the session "encryption" was triggered by a "session" (for example: TCP) between two hosts (each behind their respective ends of the tunnel). Additional meetings (for example: TCP) between different hosts on two sites, do not need other IPSec security associations. Security associations previously established IPSec supports all traffic defined by the ACE in the ACL crypto.

  For each extra ACE in your ACL crypto, you would see the creation of a pair of IPSec security associations (assuming traffic defined by the ACE triggers it) extra.

  If you need to set the layer 4 criteria (e.g.: TCP port 80) in an ACL crypto, that would be horrible. IPSec security associations are negotiated for each combination of source/target port used by a host. For example: A single host visiting a single web site (by the crypto tunnel), would open in general multiple TCP sessions (each with a different source port), and IPSec security associations are negotiated for each TCP session. This would quickly deplete resources on the cryptographic endpoints.

  We generally use P2P GRE or love with IPSec to swap info dynamic routing between sites. Because the traffic between sites is encapsulated in GRE, only a single proxy is needed.

  edg01 #show crypto ipsec his

  Interface: Tunnel0
  Tag crypto map: addr Tunnel0-head-0, local

  protégé of the vrf: (none)
  local ident (addr, mask, prot, port): (/ 255.255.255.255/47/0)
  Remote ident (addr, mask, prot, port): (/ 255.255.255.255/47/0)

  In this case, a single proxy is used. IP addresses are external physical IP addresses of crypto tunnel endpoints. Mode of transportation (where the 255.255.255.255 masks). The '47' is the GRE protocol.

  * Note: Sometimes, each cryptographic peer begins negotiations with the other, causing two bidirectional redundant ISAKMP SAs.

• Save data in several collections of data control

  Hello

  In another post (https://forums.oracle.com/message/11094155), I asked how to merge data from several collections and display it in a table. FrankNimphius gave me the right answer. I now have my table with merged data from my control of data collections. But now I have reverse request: the table must allow to insert new lines and to store the data in the model represented by all of these collections.

  I saw this blog https://blogs.oracle.com/jdevotnharvest/entry/how_to_add_new_adfand it is great, but works with a collectionModel, but the idea is exactly the same thing, just with several collectionModels in a parent one.

  The table is not lined with a collectionModel, it is bounded to a list < MyObject > in my managed bean, in order to control the integrated data to create/delete operations from the parent collection do not work.

  Another thing is: for me the model is a black box, I don't know anything about the model, I just know the datacontrol.

  Thank you!

  Hello

  If you only have access to the data controls then it has no option to combine the two data sources in a single data control (for example, Pojo). Go with a suggested abstraction managed bean, the option I see is to expose a method in the managed bean that you can use to create a new empty - list entry. This then will be displayed as a blank line in the table after PPR.

  The trickiest part is later - when you submit or commit the new line - to manually create new lines in other iterators or update other data sources accordingly (for which you will need to know what information goes on what iterator control or data). If other data controls are not BC of the ADF, and then to persist new lines, you will need to explicitly call the methods exposed on the data controls. So what you basically generate is a managed implementation bean of a two-phase commit. And then there's the case of deletion to consider as well.

• tab control event link

  I'm working on a program which requires me to bind two different tab controls.  I tried to implement a case of the event, but I don't know how to get it to link page 1 control 1 to page control 1 2, page 2 of control 1 control 2 2 page, etc...  Any help would be greatly appreciated.

  I would recommend a local variable rather than the value property node.

  Of course I do not understand why you do not just use a single tab control that is twice as wide, for example?

  What is the idea behind a code extra stuff?

  In addition, you could do a tab control the master and turn each other into an indicator. This way one can be used, but the other will always follow if they are wired together and placed in an event of value has changed. (Hide the tabs on the second).

• Set up parental controls for 1 child on two computers

  Here's the scenario that I have and I would like some help to determine if it is possible to what I want to do.

  My wife and I just bought two Surfaces, one of her and for me.  We have a son who we know that we will share our devices with.  It will probably use his more than mine.  It has a Microsoft Account because he has an Xbox Live account, thanks to our family of Xbox subscription.  I wanted to lock him on Surface machines using parental controls, but here is where I am currently.

  (1) I have set up Microsoft account my son on the Surface of my wife and indicated that it is on behalf of a child when I did.

  (2) I used my wife's account to configure all settings families on behalf of my son, such as the allocation of time, hosted the games and sites, etc..

  (3) I signed up for the family web site by using the account of my wife and could see everything.

  (4) I then created Microsoft has my son on my own Surface, also indicating that it is on behalf of a child when I did.

  But now I'm stuck.  I was really hoping that the same settings we had a machine would be then on the other account, but appears not to be the case.  I don't see his machine within the parameters of the family and she can't see mine.  When I try to add him to my family, he said "this person has already been added to the parental control.  So, it is a primary, and so I am.  Here are my questions:

  (1) how can I set where I am primary and my wife is a secondary antibody (or at least a parent who may approve things)?

  (2) will be the security settings, we have set up the synchronization of one single machine with the other somehow or we must manually preserve us allowed applications, etc all in harmony between the two machines manually?

  Hi Mike,.

  What I mean by my statement is that as long as the child is managed by a single parental control (for example you as the account parent principal, manipulation of the child), the settings on the Web site will be synchronized on all machines).

  Regarding your second question, it would be necessary on behalf of primary parent to have a user account for both computers. It would be better if you remove parental control on both machines first configuration so the settings would be better implemented according to the configuration you prefer.

  Thank you!

• Tab control with control buttom

  Hello

  I have a system with a single tab control and works fine, but when I change the program and to put two buttons to change the tab the system does not work.

  Can you help me please?

  Attached the two programs.

  You have removed the timeout event once you let him down on the block diagram. Recreate it is no different than creating events to change the value for Boolean values. Simply select the Application as the event source.

  I don't know what you mean by a digital constant or a wire inside the structure of the event. The only constant you need is a value connected to one terminal of the time-out period and it is outside of the structure.

• WHY IS THERE NO PARENTAL CONTROLS FILTERS ASSOCIATED WITH EATING DISORDERS?

  I know that I can ban specific websites using Parental control filters, but when Microsoft will add a way to filter the news of dangerous on weight loss, dieting, etc.. ? It is too easy for children to find the BMI calculators, feeding sites and other things of that nature and mistreat them. I could turn on each single parental control and my child would probably still managed to use a search engine to access a Web site that could be detrimental to her recovery. I can't type in a thousand of banned sites. It would just be easier to ban its ability to search for a specific word.

  So I would like to see a filter added to Vista, XP, and Internet Explorer that allows me to forbid my child looking for a specific word associated with consumption of issues, issues of body image, eating disorders, weight loss, etc.
  These topics are just as dangerous as alcohol, nudity, blasphemy, weapons, etc. IF NOT MORE SO.
  And with so much pressure from the media, there are more and more children using the internet to fuel this problem.
  It's time to give parents a chance to help protect our girls (and boys!) preventing them from surfing for such things!

  You can give your Microsoft ideas directly on this link:

  But there is a better way to achieve your goals, rather than through your operating system. Set up a free account at OpenDNS and choose your own filters. MS - MVP - Elephant Boy computers - don't panic!

• How to get the vertical scroll bar is displayed for control panel

  Hi there, Im a beginner in Flex and I'm working on my first application for a client. I have the most difficult time to get a vertical scroll bar to work for a Panel control, that I use. Here's the overview:
  
  1. I have a control of the application with a horizontal layout
  2. I have a Vbox left with 2 panels on top of the other,
  3 - I have a Panel on the right with a bunch of text controls just above another.
  
  the application looks like this. Think fair spaces and dashes since this wont let me enjoy the areas:

  MY PROBLEM: I would like the application to stay confined to the browser window and have scroll bars appear in the right panel when text controls contained too long for the browser window. Yet, I can't make it work, Ive tried to use clipContent = true and activation verticalScrollPolicy but nothing seems to make the sign on the right contrain at the height of the browser window.
  
  I have a feeling it's something really simple so any help would be LARGELY APPRECIATED!

  I have it! Thanks Darin for work through this with me. Liike looks like, I really need the Hbox, so do the layout of Panel = "absolute" as josh suggested. Then wrap all text with a vbox controls, Viola! I get scrolling as expected! Here's the final MXML:

• cRIO ethercat application error

  I have a cRIO-9074 connected to and AKD via EtherCAT drive, running in standard mode.

  Simple straight line move using a VI express softmotion.

  It works fine except when I force the engine to stall, a strange thing.

  When I take the engine yet it will suddenly reverse direction rotates at a speed faster than the requested speed rear forward.

  The faults of the ADK out but it takes 100 to 400 ms to turn off the power.

  The AKD displays F 503 and Labview indicates an error code 6A 3130.  This resulted in "phase failure AKD.

  Relavent part of this error is: "the excessive power single-phase connection load".

  Of course I am inducing power over load so expect this fault, but the reverse rotation before the AKD Cup feeding is strange.

  I tried to reproduce this using the Kollmorgen Workbench software, but so far it only happens when Labview is controlling via EtherCAT.

  Hello Brians,

  Taking the engine beyond normal limits of operation may cause unexpected behavior. It is never recommended to intentionally block the engine. In this case, it seems that LabVIEW is trying to remove the constraints inherent in the system in the case of a stall by reversing the motor. The reason why you do not see this behavior in the Workbench is because it does not contain the control algorithms that are present in LabVIEW. In addition, I am curious about how to determine the time the motor runs in reverse; 100-400 ms seems very specific. If the pitch of the engine is possible in your code, I need to program under a security to handle this situation and perform all measures requires your application in the case of a stall.
