Binding a Shared Varable to multiple MODBUS registers

A simple question, but can't seem to find an answer:
I have a project library with a serial MODBUS i/o server setup. In this library I have several shared variables that are bound to registers on the remote device through the MODBUS protocol, and this works fine if each variable is bound to read a single register (e.g. Modbus1\D400001). What is the appropriate syntax to bind a single shared variable to multiple consectutive registers? If I set the Shared Variable type to "Array of UInt32" can I specify something along the lines of Modbus1\D400001-D400100 ? So far this doesn't seem to be working, or at least hasn't displayed anything when creating an array indicator and binding this shared variable to the indicator. Thanks,

Sorry, forgot to mention this is LabView 9.0.1 with the DSC module.

Hi Underscore_c,
Take a look at this help document:
http://zone.ni.com/reference/en-XX/help/371618E-01/lvmve/dsc_modbus_using/
This document should also be in your LabVIEW help. You'll notice that you can call an array of registers by preceding the address by "A".
For example,
A400008L8 is an array of values of length 8.
There is an example called "Modbus Datatype Extension" that should get you started in the right direction.

I/O Server: Writing 3 Modbus registers in one operation

Hello,
Can the I/O Server use Modbus Function Code 16 (preset/write multiple holding registers)? Essentially, my CompactRIO needs to send a 48-bit integer to a slave device, which means I need to write 3 registers.
I found a way to do it without I/O Server (http://zone.ni.com/reference/en-XX/help/370622M-01/lvmve/modbus_master_write_read_multiple_holding_registers/ ), but I was wondering if I could do the same using I/O Server.
Thanks!

Hello JKSH,
Unfortunately, a bound shared variable cannot read\write from 3 registers at once automatically. Below is a document which details Modbus I\O Server bound shared variable capabilities.
Using Modbus I/O Servers (DSC Module or Real-Time Module)
http://zone.ni.com/reference/en-XX/help/371618G-01/lvmve/dsc_modbus_using/
You do have the option to access two adjacent 16-bit input registers as one 32-bit shared variable but not 48-bit.

Hello All,
we have created shared folder on multiple client machine in domain environment on different 2 OS like-XP,Vista, etc.
from some day's When we facing problem when we are access from host name that shared folder is accessible but same time same computer when we are trying to access the share folder with IP it asking for credentials i have type again and again
correct credential but unable to access that. If i re-share the folder then we are access it but when we are restarted the system then same problem is occurring.
I have checked IP,DNS,Gateway and more each & everything is well.
Pls suggest us.
Pankaj Kumar

Hi,
According to your description, my understanding is that the same shared folder can be accessed by name, but can’t be accessed be IP address and asks for credentials.
Please try to enable the option below on the device which has shared folder:
Besides, check the Advanced Shring settings of shared folder and confrim that if there is any limitation settings.

No, Lightroom catalogs cannot be on a networked (shared) drive, and they do not support simultaneous multi-user access

What is the best way to create shared variable for multiple PXI(Real-Time) to GUI PC?

What is the best way to create shared variable for multiple Real time (PXI) to GUI PC? I have 16 Nos of PXI system in network and 1 nos of GUI PC. I want to send command to all the PXI system with using single variable from GUI PC(Like Start Data acquisition, Stop data Acquisition) and I also want data from each PXI system to GUI PC display purpose. Can anybody suggest me best performance system configuration. Where to create variable?(Host PC or at individual PXI system).

Dear Ravens,
I want to control real-time application from host(Command from GUI PC to PXI).Host PC should have access to all 16 sets PXI's variable. During communication failure with PXI, Host will stop data display for particular station.
Ravens Fan wrote:
Either. For the best performance, you need to determine what that means. Is it more important for each PXI machine to have access to the shared variable, or for the host PC to have access to all 16 sets of variables? If you have slowdown or issue with the network communication, what kinds of problems would it cause for each machine?
You want to located the shared variable library on whatever machine is more critical. That is probably each PXI machine, but only you know your application.

Multiple shift registers in For loop

I'm using multiple shift registers to find the number of different string in a string array. However, the shift register got refreshed every time it finds a different string and returns back to 0. How can I have the register remember its previous value after it encounters a new string value?

You should think about making your code scalable. At the moment, you need to re-architect the VI from scratch whenever the sensor names or their number changes. If you suddenly have 1000 sensor names, the code would be unmamangeable because the sheer number of cases and shift registers!
Attached is an simple alternative. As you can see, the code remains the same, even if the number of sensors or their names changes in the future. See if it makes sense. (You can easily modify it to also count unrecognized names, for example).
Modify as needed.
Some other possible bugs in your VI:
You should initialize the shift register with zero, not one. Right now the results are one too high.
Case "B" is actually "B." and the count is only accidentally correct because it is also the default case and there are no other sensor names (e.g. F) in the input array.

What is the best approach to converting LV7.1 tags to LV2012 shared variables in multiple VIs?

What is the best approach to upgrading from LV7.1/DSC tags to LV2012/DSC shared variables, in multiple VIs running on multiple platforms? Our system is composed of about 5 PCs running Windows 2000/LV7.1 Runtime, plus a PLC, and a main controller running XP/SP3/LV2012. About 3 of the PCs publish sensor information via tags across the LAN to the main controller. Only the main controller is currently being upgraded. Rudimentary questions:
1. Will the other PCs running the 7.1 RTE (with tags) be able to communicate with the main controller running 2012 (shared variables)?
2. Is it necessary to convert from tags to shared variables, or will the deprecated legacy tag VIs from LV7.1 work in LV2012?
3. Will all the main controller VIs need to be incorporated into a project in order to use shared variables?
4. Is the only way to do this is to find all tag items and replace them with shared variable items?
Thanks in advance with any information and advice!
lb
Solved!
Go to Solution.

Hi lb,
We're glad to hear you're upgrading, but because there was a fundamental change in architecture since version 7.1, there will likely be some portions that require a rewrite.
The RTE needs to match the version of DSC your using. Also, the tag architecture used in 7.1 is not compatible with the shared variable approach used in 2012. Please see the KnowledgeBase article Do I Need to Upgrade My DSC Runtime Version After Upgrading the LabVIEW DSC Module?
You will also need to convert from tags to shared variables. The change from tags to shared variables took place in the transition to LabVIEW 8. The KnowledgeBase Migrating from LabVIEW DSC 7.1 to 8.0 gives the process for changing from tags to shared variables.
Hope this gets you headed in the right direction. Let us know if you have more questions.

How to config a shared cache for multiple environments with C API

How to config a shared cache for multiple environments with C API? Just like Java edition. Chapter 2. Database Environments
I want to open large number of databases, at least 10,000. But as the counts of databases opened increase, the db->open operation become very slow. It almost cost 2 hours to 10,000 databases.
So I try to distribute these databases to multiple environments ( for example, 5 envs ). And in order to improve the efficient of memory use, I want to share cache between envs.

Hi,
It is not clear what you meaning about multiple environments. Do you mean these environments are in different directories or in the same directory ? If you mean environments in different dirs share the same cache, it is interesting why you need that.
If you do not use DB_PRIVATE to open the environment, the created cache will be on disk, in the environment directory, so it can be shared by multiple processes and multiple threads. Currently, the cache file is in the environment directory, and we do not support specifying a separate directory for cache only.

Use buffering and psp with datasocket-VIs and without any binding and shared variable node

Hello,
I'm using LV 8.5.
I'm trying to develop a multiplatform (windows and mac os x) and multi-computer application. II want to get executables running on each device, communicating through the network. Communication process includes datas (such as images) and events messages (something like "Hello, I got an error" or "youyou, my work is done" or "I'm hereeeee!!!!...."). I do need a communication without any loss of data.
I worked a lot and wanted to test a psp-based design, without any binding nor shared variable node (mac os...) using data socket VIs and SVE buffering.
I managed to :
- deploy shared variable library dynamically (even in an executable)
- communicate between two PCs with datasocket VIs
However, I never managed to enjoy buffering (even locally with one VI doing the deployment and writing datas and another one for reading).
I worked hard (dynamic buffering setting, dynamic buffering watching like in http://zone.ni.com/reference/en-XX/help/371361D-01/lvconcepts/buffering_data/ and in the example "DS send image" and "DS receive image" in the labview examples, trying to use "?sync=true" in the URL, etc...) but no way to get things work.
I attached a jpeg of an example of receiver and sender. I use wait commands in both receiver and sender to test buffering
Receiver do receive datas (the last written) but buffering doesn't work.
Did somebody did that before ? (better than me...)
Thanks
Bo

Hello,
Indeed my problem has been solved. My error : in the While loop of the receiver VI, I always reactualize the PacketsMaxBuffer and OctetsMawBuffer parameters, what resets the buffer and make it appears ineffective.
I now set the PacketsMaxBuffer and OctetsMawBuffer values only once at the begining of the VI and the psp buffering works perfectly.
Sorry for the desagreement...

Multiple modbus sessions

I need to connect slaves with RS232 port to PC, so each slave will have one PC serial port connected to it. And the protocol is modbus. Will Labview/ OPC support more that one serial port on the PC with modbus protocol?

No problem -- you may want to just repost in the LabVIEW forum.
By the way, and for the record, Lookout can do this i.e., have multiple Modbus Objects via multiple serial ports.

Sharing jsp between multiple controllers

Is there a way to share a jsp between 2 different controllers?
If I put the shared jsp in its own directory and the 2 controllers in their own directories - I seem to be able to use netui:anchors and specifying the fully qualified "href" attribute - but not the "action" attribute. For example this works (but means I have to specify the exact controller):
<netui:anchor href="/portlets/Controller1/findAction.do">
            find
</netui:anchor>This does <b>not </b>work:
<netui:anchor action="findAction">
            find
</netui:anchor>Additionally, if I want a form to be on this shared jsp - I don't know of a way to use the netui tags to accomplish this... This example results in an error (as if it's trying to find the action in Global.app):
        <netui:form action="submitSharedForm">
            <table>
                <tr valign="top">
                    <td>Foo:</td>
                    <td>
                    <netui:textBox dataSource="{actionForm.foo}"/>
                    </td>
                </tr>
            </table>
            <netui:button value="submitSharedForm" type="submit"/>
        </netui:form>Are there other better techniques for sharing jsps between multiple controllers (jpf)? The only other thing I was thinking of trying to have a jsp found within the same directory as the controller include the shared jsp (which seems kind of tacky)...

You may consider using a base pageflow controller that has the common JSPs
in its directory. I have done that before like this:
// inheritLocalPaths=true lets us inherit the JSPs from the base pageflow
@Jpf.Controller(
inheritLocalPaths=true
public class MyChildController extends MyBaseController

Designing an automated way to Convert two modbus registers in a useable number

I have two modbus registers that contain data. example reg1 8245 and reg2 13361. From them I convert and end up with 541 then convert to 5.41. It is relatively long equation. I will have to repeat nearly 600 Times per site. Is there a way I can utilze the same equation without having to type in the same thing over and over? Hopefully this give enough detail. Thanks James

You can create an Aggregate object for this Expression of yours. And then use this "custom" (Aggregate) Object in your other processes.
See Online Help for details on the Aggregate Object.
Hope this helps.

Dynamically enabling/disabling opc-binding to shared variables?

Hi.
I've got some shared variables binded to my OPC server, but sometimes some variables need to "ignore" the OPC updates and and be simulated, and in some cases, all of the variables.
So, I've got an application to dynamically change the shared variables properties: Network.UseBinding and Network.URL to "connect to" or "disconnect from" the OPC server, but is there a way to "unbind" the whole library from the OPC quickly and restore it back when need it?
I tried creating and deleting the IO server programatically but the variables go "bad"...
Is this is a good practice or should I change the method?

Hi Keptat, you can bind them directly to the OPC sever but you need to add
psp: at the begining.
For example
   psp:\\localhost\IOServer\ModbusSlave1.000001
   psp:\\aebenjamin\IOServer\OPC1.Channel_0_User_Defined.Ramp.
   psp:\\ host \ library\IOservername.register
An easy way to find the complete address y bind a Variable with psp
binding to the OPC server and you will get the path.
In the example code it gets the psp address from a Library, but won't get
you the directions of the registers inside the IOserver, so you need this list
manually.
Another option is create 2 libraries one with the variables binded to the IO
Server and the other binded to the simulated info, in this case you just have
to point to the library, and get the address of all variables.
Also you have to make sure the OPC server is deploy and you can see it
in the Distributed System Manager

Sharing Library across multiple machines

I have a shared network drive in my house and want to have multiple computers (two Macs and one PC) all have access to the same library. I have all of the machines pointing to the same mucis folder so that is not a problem.
I would like to be able to add music to the library from any of the machines but then be able to update the individual iTunes screens to show all of the music in the folder.
After putting in several hundred songs and going to each machine and using Add Library (Add Folder to Library on the Windows PC), I now find that I have duplicated the MP3 files in the album directories. The iTunes screens on each computer only shows the songs listed once but the files are duplicated.
There has to be a way to do this without duplicating all of these files.
Thanks for any suggestions.
David

David,
there is no auto-sync feature build-in into iTunes.
As a workaround when adding/importing music put those tracks on a seperate playlist (or use a smart playlist) and export this playlist to a shared folder.
Then import this playlist on your two other computer.
To avoid dupes disable in iTunes Preferences Advanced "Copy files to iTunes Music Folder ...."
