RT Reboot Controller and RT Ping Controllers with PXI-8184 and LabVIEW 7.1

Hi,

 

I?m having problems using RT Reboot Controller and RT Ping Controllers from the Real-Time Utilities palette with LabVIEW 7.1, but only with PXI-8184 controllers.  This work fine with PXI-8175.

 

The attached VI will list all the 8175 on the subnet, but none of my 8184.  However, I can ping and FTP all my 8184.   If Local Subnet? is TRUE, I don?t get any error, but the RT controller doesn?t reboot.  If it is FALSE, I get: Error 63 occurred at TCP Open Connection in FPC open connection.vi->RT Ping Controllers.vi->MssUT-RebootController.vi.  All 8175 and 8184 are on the same subnet and ahve the same IP settings (mask, gateway, DNS server).  None of them is locked with a password.

 

What?s wrong with this VI and 8184 controllers?  Please don't tell me to upgrade to LabVIEW 8.2, I can't, these systems are under production in 3 sites in 2 countries.  We already have 16 PXI-8175 deployed that control cars from trains in hump yards.

 

Thanks,

 

Patrick.

The issue is that the PXI-8184RT was released after LabVIEW RT 7.1. The RT Ping Controllers uses an internal protocol to find ethernet base devices. It is actually used on more than just RT targets as other products like GPIB and Serial Enet devices. The RT Ping Controller VI in LVRT 7.1 uses a white list of known RT targets to provide you with only the RT targets. <a href="http://digital.ni.com/public.nsf/websearch/BFF8232A17B0B70586257021007B228B?OpenDocument" target="_blank">KB 3MEGCEUW</a> contains and updated version of the library with that VI.  
&nbsp;
FYI,&nbsp;rather than update that every time a new RT target comes out, we've changed that to being a black list of non-RT targets. This means if a new non-RT ethernet based device came out it might mistakenly&nbsp;be returned as an RT target but we thought that was better then your RT target&nbsp;not showing up.

Can I trace and probe active code in a 7030 RT controller using Labview 6.1 while the RT engine is running?
Can I trace and probe active code in a 7030 RT controller using Labview 6.1 while the RT engine is running?

Using the cFP controller with only LabVIEW and FIELDPOINT software but no LabVIEW RT
I have a cFP-2020 controller and cPF-AI-100 modules which I intend to use in a small project. I do have LabVIEW and FIELDPOINT software but I dont have LabWIEW RT software. Is it possible to use the cPF controller with only just LabVIEW? if yes, I would like to be advised how. Thanks Dear Chuma, It is not possible to&nbsp;set up your system without Labview realtime module. There are system integrators who can build a executable for you. You can search for a alliance member by using the following link; <a href="http://sine.ni.com/apps/utf8/niaa.search_display" target="_blank">http://sine.ni.com/apps/utf8/niaa.search_display</a>&nbsp;Or call your local NI branch office. But if you are planning to do more realtime projects&nbsp;in the future this wouldn't be costs effective. Another option is to use compact fieldpoint pc controlled backplane (so there has to be a PC to control your compact fieldpoint system (not deterministic)). You can do this by using the compact fieldpoint ethernet backplane; <a href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527" target="_blank">http://sine.ni.com/nips/cds/view/p/lang/en/nid/202527</a>&nbsp; Good luck with your project, and please let me know if there are any questions, &nbsp; Martijn ...

LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
Y am i getting this msg? Hi, muks, This happened because "...LabVIEW does not compile code on the block diagram that does not execute. For example, LabVIEW does not compile any code that exists within the inactive subdiagrams of the Conditional Disable structure. In addition, LabVIEW does not compile code within a Case structure that has a constant wired to it that would not execute the case with the code..."In the other words, if you have case structure, which is wired to T/F constant, then prior to version 8.x both cases will be compiled. From version 8.x the only "executed" case will be compiled. So, LabVIEW replaces constant with control for ensure that both cases will be compiled as before. refer to <a href="http://zone.ni.com/reference/en-XX/help/371361A-01/lvupgrade/labview_8_0_features/" target="_blank">this document</a> best regards,Andrey.

labview 7.1.1 rt application slows system clock by 1 second evry 25
Hi, I have an application that I'm trying to run on Dell 620 laptops.It's running under Labview 7.1.1 RT and comunicates to a field point 1001 485 network module every 125 ms. via a NI ENET to RS 485 converter.&nbsp;My problem is that when the application is not running the laptop system clockis fine. But, whenever I run the application, the system clockslows so that it loses about 1 second out of every 20.The problem is repeatable between 2 different machines, and does notseem to be related to antivirus (disabled), firewall (disabled), cpu loading(cpu use is less than 10%) , ram or video (one machine has onboard video,the other has a video card).Any ideas?thanx:-&gt;tb Hi Terry, This level of fluctuation of the internal clock is unexpected, so I would like to get some more information about the system: - How are you controlling the timing on the host machine (i.e. timed loops,&nbsp;specific wait functions, etc)? - How are you communicating data between the target and the host? - Is the Real-Time code running as an executable on the target, or are you controlling it from the laptop? - How are you monitoring the system time? - Can you narrow the code down to some specific functions that can reproduce the error?&nbsp; Let me know some of this specific information, and include a basic VI if it is reproducible on a small scale, so that I can investigate this behavior further.

can Labview 7.0 control an instrument without the labview driver?
hellow,i have an instrument which do not have the labview driver,its output signal is RS232,so can i use labview7.0 to read the signal? thanks! Another possible option is to use the Instrument I/O Assistant. It is an interactive tool that generates Instrument I/O and response parsing code for you. It is very helpful in establishing a connection and helping parse instrument response data. It is pretty high level and basic, so if you want to utilize any special serial VISA functionality it may not go as deep as you would like - but it can definitely help get you started. ...

Re: LabVIEW and LabVIEW RT?
Hello Iman, I will try to illustrate it with an example since it all will depend on the type of application you would like to implement. Let's say you would like to implement an application where you log data, maybe exchange data with databases and you acquire a bunch of data points at a time not performing any type of control and where high determinism is&nbsp;not needed. In this case LabVIEW for Windows work great. If you on the other hand would like to implement a closed-loop application where you need high determinism and reliability and will acquire data point by point you would use LabVIEW RT which is an add-on to LabVIEW. I.e. you need LabVIEW + LabVIEW RT when developing an RT application. ...

labview 7.1 Events read previous value of control
Hi I am experiment with labview events. I have button that once its value is change (ie clicked) it would fire an event to do an I2C write to a device. The data to be rewriten is in a numeric control. Labview however writes the previous value in the numeric control rather than the current value. I've verified this via scope on the I2C signals. Also i've used probes and break points in labview to see what is going on and it does confirm that old value is being rewriten. To make things more interesting it seems the right values are brought to edge of the event box however the pre...

I think my query is clear,please reply me soon......... Pratima Hi Pratsha, The 9004 is NOT a multicore controller, so being able to select which core a task runs on does will not improve performance.&nbsp; Also, 4 time-critical loops typically is NOT desired.&nbsp; That is because time-critical means the MOST important operation compared to other parallel operations.&nbsp; If all you have is 4 timecritical operations and no others, then all the loops are the most important, thus making none of them important.A reason to upgrade to LabVIEW 8.5 with a cRIO is the <a href="http://zone.ni.com/devzone/cda/pub/p/id/303" target="_blank">fixed-point data type</a>.&nbsp; I would look into that if your interested.

How to easily control multiple controls in labview
How can I easily control multiple controls with a single write to in Labview? For instance, I need to update 50 different boolean indicators. When I update them one at a time I use a cntrl refrence in my event structure, but outside of an event structure how can I easily cycle through them and update without making 50 local variables if I need to do them all at once? Why don't you use an array of boolean indicators? Have a look at the example attached <a href="http://forums.ni.com/ni/board/message?board.id=170&amp;view=by_date_ascending&amp;message.id=204328#M204328" target="_blank">here</a>, which can also be applied to this. You should usually avoid updating the value of a control from more than one place, though (unless it's something like initialization, where you can guarantee not having race conditions). Other alternatives: using an array of booleans or using the picture control to create the image. The way i use these booleans in my UI, I had to make them separate so I could arrange them in a user friendly way. And yes this is just for initialization so they won't be getting updated in two places at once. ...

How do you control seperate motors with Labview through a remote control?
Forgive me if I am not typing the question correctly, or if it is a stupid question. I am only fourteen and only started learning about Labview.. I would appreciate all help possible. Thanks What type of motors are you trying to control?&nbsp; How do you have them/plan to have them connected to your computer?&nbsp; When you say you want to control remotely, do you mean that you don't want them connected to a computer or that you want to communicate remotely through your computer (no cables)?&nbsp; The more information you can give the better help you will receive. Cheers Hi LouidSilence, It would also be helpful to know what version of LabVIEW you are using.&nbsp; It's impressive that your starting to learn LabVIEW at such a young age, it will be challenging but worth it!&nbsp; Well first off, thanks for asking questions to my questions, it helps me too :) The kind of motors I am trying to control are IFI Robotics Multi-Speed Motor Connect to PWM or RLY port (12 volt)..

The first thing you need to do is find out if your BIOS has "Hardware Monitoring" Most ASUS "do it yourself" motherboards have hardware monitoring built into their BIOS. I don't know if computers you buy from companies like Dell or HP have hardware monitoring capability built into their BIOS. Next when running in Windows you need software that can retrieve the data from the BIOS. I don't know of any free software that does this.
