Communicate between TS Executions

Hello,
Communicating between two threads in TestStand is easy enough using the Notification step type, but it seems like notifications cannot be used to communicate between two different executions. Is it possible to use the notification step in TS to communicate between two different TS executions? What is the best way to send messages between two TS executions?
Thanks,
Kevin

Scratch that. I believe I've realized notifications do work between executions.

A problem that how to communicate between PLC S7-300 and IA Server

The PC running the OPC server is connected to PLC S7-300 via the RS232 serial port and the Siemens RS232-MPI adapter (product no. 6ES7972-0CA23-0XA0).
But I encounter such problem when I create an object(S7_HMI)in IA Server:
Step 1：

First of all, Thank You very much for Your answer.
I'm using the TS Adapter that make the conversion from MPI to the serial bus.
I have made yet control panels to supervisor systems with Omron PLCs and I correctly use the DataSocket with the DSC module: with Omron PLCs I've never had any problems of communications. The problems is now with Siemens. For the communication between control panel and PLC I have to use the internal modem of my computer and the OPC is S7_MPI of IA opc Server.I wondering if this OPC is ok for modem communications (inside there is a form to insert the phone number of the remote station) or if every kind of modem are compatible with S7-300 modem it has inside.I've noted that my computer modem don't do the phone number when i run the front panel!In running mode, if I take a look to the Block Diagram and I click the "Highlight Execution" button I don't see any animation on the code generated by the HMI Wizard to connect the only one tag to the DataSocket URL.
Have You any other suggestions to solve the problem?

Can NI-PSP be used to communicate between machines developed with different versions of LabVIEW?

Hi all,
A customer has a large PC application developed with LabVIEW 2010 SP1.
They would like to add extend their system with a cRIO-9075. According to this document (ftp://ftp.ni.com/pub/devzone/tut/crio_software_versions.htm ), the minimum supported version of LabVIEW (with Scan Engine support) is LV 2011.
To minimize risks, it is preferred that we don't upgrade LabVIEW for the main application, which is atively being used in production.
I was thinking of developing the cRIO software in a newer version of LabVIEW (say, LV 2013 SP1), and using shared variables only to communicate between the PC and the cRIO.
Is this a viable option? Does it matter if the PC and the cRIO have different versions of the LV runtime?

It shouldn't matter, but then with shared variables you can never know for sure -- there are so many things that can make them break.
You might be money ahead to write the comm using TCP/IP. You know that will work.

Communicate between SWF & Global static vars

Sorry for my inglish...
I’m having some problems on getting full communication between loaded SWFs. I'm totally stuck and my timing is running.
Suppose the following scenario:
Father-SWF has his own class and loads A-SWF and B-SWF. A and B SWF has his own class and package. To exchange values and run functions between SWF, I’m using a Global class with public static vars. Some of this vars are function, example:
GLOBAL CLASS WITH STATIC VARS (com. with other class and package beetween SWF)
package scripts
     public class GlobalAct
          public static var mainStage:Object;
          public static var myFuncGlobalA:Function;
          public static var myFuncGlobalB:Function;
MAIN CLASS FATHER SWF
package
     import flash.display.MovieClip;
     import scripts.GlobalAct;
     public class FatherClass extends
MovieClip
          public function FatherClass():void
               GlobalAct.mainStage
= this;
               GlobalAct.
myFuncGlobal = myFunc;
          public function myFunc():void
               //some wird stuff
A_SWF CLASS
package
scripts
     import flash.display.MovieClip;
     import scripts.GlobalAct;
     public class Layout extends
MovieClip
          private var someMc:MovieClip;
          public function Layout()
                someMc
= new MovieClip();
                someMc. addEventListener(MouseEvent.CLICK,
mouseFunc);
          public function mouseFunc (evt:MouseEvent):void
               GlobalAct. myFuncGlobalA ();
B_SWF CLASS
     Similar to A-SWF class but with other kind of functions…calling “GlobalAct.myFuncGlobalB();” for example.
This works great, when I run Father-SWF, it load every SWF and functions run from SWF to SWF.
The problem happens when I load Father-SWF in another SWF. There is a MAIN-SWF with his own set os class and a Global static vars Class.
MAIN-SWF loads a SWF that will load Father-SWF into the MAIN-SWF.
WORKING
Father-SWF -> many SWF that could load other SWF
NOT WORKING
Main SWF -> SWF -> Father-SWF -> many SWF that could load other SWF
When this happens none of the Global functions seems to work. The other Global vars seems OK, only function vars seems not to work.
I only get the error: “TypeError: Error #1006: value is not a function. at scripts::Layout/ mouseFunc ()” when I try to click a button inside A-SWF.
Does I lose my Global reference when loading the Father-SWF in another SWF?
How can I make this bullet proof and generic for every situation?
What’s the best oop practice to communicate between class and SWF on AS3?

I figured it out.

Communicate between separate VI's using OOP

Hello,
I have a question relating to how two separate labview programs can communicate with each other. Specifically I want to make a temperature controller using the OOP features of labview, and implement a Model-Viewer-Controller design.
I would like the Controller Object to launch the Viewer (the GUI) object. My question is though, how will these objects communicate between themselves?
The Viewer object is used to set the desired temperature, and display current temperature. Some how it must communicate this to the Controller object who will use its Model Object to create the correct response (i.e. change the set temperature of some hardware device, although generically the Model Object is an abstract class, to be implemented by it child classes), and then communicate back to the Viewer with the current temperature.
I was wondering if the Vi server tools are the right for this?
Thanks,
Paul.

Hi Bob, thanks for your post.
Here is what I want to program using an object oriented approach.
I want to make a temperature controller, which has three objects. A Controller Object, a model object, and a view object. The controller is a mediator between the model (which will talk to the hardware), and the view (which will display the current temperature, and where the set temperature can be changed).
The controller will have a method like myController.addView(Object View), and addModel(). So when I run the controller and give it a View object, I want it to open a window with a temperature indicator, and a set temperature control. When the set temperature is changed, the view object will notify the controller of this change (using an event), and the controller will run a method on the Model object which will control some piece of hardware setting its Temperature to a new value. The model will also send events (from time to time) to tell the controller that the temperature (of the device) has changed. The controller will then tell the view to update its temperature indicator.
I have found a nice article about implementing the Model-View-Controller design pattern using Java (I am a java programmer, trying to use labView). The article is here: http://java.sun.com/developer/technicalArticles/javase/mvc/
I would like to program this in labView.
Also I would like to make my code reusable as much as possible. So the controller, view, and model objects will all be abstract classes, to be implemented by code specific to the device. Also some devices will require more than one type of view object displaying the data in different ways.
I hope this makes what I am trying to do more clear.
So basically I want the View object to open a window with a temperature indicator and a set temperature control. I want the controller object to start the view object and tell it to open the window. But I am not sure how to do that with labView.
Thanks, any advise will be valuable!
Paul.

Communicate between two backing beans

Hi !
How can I communicate between backing beens ?
I would like to put data from Bean1 to Bean2.
This is my code in Bean1, I try this:
Bean2 b = new Bean2();
//... b settings...
//Map map = facesContext.getExternalContext().getRequestMap();
//map.put("Bean2", b);
HttpServletRequest request = (HttpServletRequest)facesContext.getExternalContext().getRequest();
request.setAttribute("Bean2", b);
So I put Bean2 instance in request, but JSF created new instance :(
How can I solve this problem ?

Communicate between 2 ipads over internal wifi only

Can I communicate between 2 ipads over internal wifi WITHOUT internet? They are on the same subnet and would have network access to each other, but it seems to IM or message between them it must go over the internet.

If you want to message between the two iPads, yes you must be connected to the Internet as the messages are transmitted via Apple Servers.

Any standard RFC there to communicate between satellite system and Solman?

Driver to communicate between LabVIEW and Omron CJ1G PLC

I am trying to communicate between my Omron PLC (Model CJ1G) and LabVIEW. I want to be able to read specific registers and be able to display and save the data in LabVIEW.
I have the "Idustrial Automation Servers for OPC" CD but my PLC model no. doesn't appear under the Omron options.
What other options do I have?
Thanks, in advance,
Felipe

Hi Felipe:
I checked in our PLC compatibility database and the only Omrom PLCs that are supported are the following: C20, C200, C500, C1000, C2000, CQM, and CPM1.
The PLCs that are suppored in the IA OPC server is based on the driver dll that was supplied to us by Omron. When newer PLCs are released, they are not included in this dll and are thus not supported. You might want to contact Omron to see which OPC Server supports that PLC. You should be able to use any 3rd party OPC Server to work with DSC which will then be the OPC Client.
Hope this helps.

Can't communicate between JS and ExtendScript

I tried this: (according to the docs it should work)
In JS
var csInterface = new CSInterface();
csInterface.evalScript('$.test()', function(r){console.log(r)})
In JSX
$.test = function() {
alert("test");
return 65656;
I'm seeing the alert, but the logged statement is empty. Anyone know how to communicate between the two?

I tried a few ways but the only way I could do it properly was pretty involved:
1) Use Socket.io to communicate between generator and extension
2) When you want to raise an "event" from JSX, update generator settings, use a unique id for your event
3) Parse the event in generator
4) Emit the event from generator to extension.

Diff between Logistics Execution and General

Hi ,
Can anybody tell me what is the basic difference between Logistics Execution and Logistics General
Thanks
Bharath

Logistics Execution
The entire delivery chain functions in this module.
Both outbound and inbound deliveries, stock transfers, picking, packing, and all other activities which are supposed to take place during the movement of a material from one place to another place happens here.
Logistics general
This link can serve some of the functions of Logistics execution, materials management, and sales and distribution also. This module by itself will not contain certain processes of its own, but it will enable the functions pertaining to all of the logistics modules namely SD, MM, LE etc. In this aspect, this is the module which covers ceratin configurations pertaining to multiple modules like product hierarchy, variant configuration etc.
Hope this helps.
Rwd points!!!

RS 232 port to communicate between cFP 2100 and Multiple cFP 1808

Hello All,
I am using one cFP-2100 (controller) and two cFP-1808 (network contoller) for a project.
All the three devices have Ethernet port, so i can connect to a network switch for communicating with the Host PC.
My question is:
All the three devices have Serial Ports (RS 232) too, Can i use those ports to communicate between the three devices (1 controller and 2 Net. controllers) and use the ethernet port in the controller (2100) only for communicating with a Host PC?
If this is possible, how to do the RS 232 cabling ?
Regards
John

Hi bjsprem,
You can connect network modules to the controller with serial. This KB shows how to do this. Hope this helps!

How can I communicate between two simulated software

Hallo,
I have confusion regarding this topic "How can I communicate between two simulated software".
1: PC with CAN simulation
2: PC with AFDX Simulation
Now i have to communicated these two pc with each other.
How can i communicated? which module from ni is best for it.
thanks in advance
BR

I recommend looking at the Simple Messaging Reference Library that NI has released. Use the TCP/IP version of it.
FYI, TCP/IP is a communication protocol that is used to communicate between two computers. It is what the internet uses. So you just need a network switch or router between your computers and you can talk to each other with their IP address.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Can Simple Data Client/Server VIs communicate between computers?

I am having trouble using the Simple Data Client VI / Simple Data Server VI to communicate between computers? Can these VIs do this ..or do they simply communicate between each other on a single computer? TIA.

NO it can be used between two computers. You have to replace the localhist string with the IP address of the computer running the server and make sure that the server computer is allowing external connections on the specified port.
