Library for Modbus ???

Hi, I have a project to control a motor system.
The communication is RS485 through Modbus via Serial.
The computer is the master and the control motor is the slave.
I have just one system to control
I found 3 free driver.
MODBUS Library for LabVIEW Version 1.21
http://www.ni.com/example/29756/en/
LabVIEW Modbus API v1.1.3.32
https://decibel.ni.com/content/docs/DOC-30140
MODBUS included in DSC module for LV2014
http://zone.ni.com/reference/en-XX/help/370622M-01/lvmve/choose_modbus_ioserver_vi/
I already made a development with 1.21 from NI.
Should it better to use Modbus library from DSC module ?
What do you suggest me ?
thanks in advance

Hi Minikisscool,
The Modbus Library for DSC is probably the more convenient to use but you need for that to have purchased the DSC module.
The option you have choosen (the free low level API) is probably the most commonly used and if you did not experience any particular troubles using it, I suggest you stick to it ; )
Have a nice day,

Labiew lib for modbus over RS485 over USB

Hi,
I have the following problem which I would be grateful for any help to solve.
I have a digital meter device (lumel NA5) which has RS485 interface, and modbus protocol over it.
A possible solution I'm contemplating is to get a RS485 to USB converter, and then talk to the device from Labview.
I found Labview library for serial and TCP/IP modbus. But is it possible to connect to this device using UCB?
Thanks,
Eyal.

You can use this
1-Port RS485/422 Interface for USB
or if you need more ports...
2-Port RS485/422 Serial Interface for USB
4-Port RS485/422 Serial Interface for USB
With this device the serial ports will show up like any other COM port, you can target it in LabVIEW or third party software.

Mod bus library for LV6.1

Hi
i'm using LV 6.1 .I need to automate an equipment that support modbus protocol RTUframing.
So is there any library for LV 6.1version. The version available on site is for LV 8.2 . Is this library compatible with LV6.1? Please solve my problem.
Regards
Thanks.

I saved for previous version from 7.0 to 6.1. I did get warnings on two of the files. All of the info is inside this zip file. I don't have 6.1 installed, so I have no idea if these will work.

Adobe Photoshop 8.0 Object Library for PSE 8 ?

Hi
I want to write a program to loop over all tags and copy the associated fotos to folders named with the tag-name. By this way I have a good structure to select the fotos on stick / DigiFrame.
I'm a Unify TeamDeveloper developer, so it's no problem for me. But: in TD I can generate the COM classes to access PSE. I think the right object library for this is Adobe Photoshop 8.0 Object Library.
I have a complete installation of PSE 8 on my computer but this Object Library is not present.
Does Adobe Photoshop 8.0 Object Library not serve for PSE8? Where can I get it?
the one I have is Adobe Photoshop Elements 8.0 Media Client 1.0 Type Library. There are some methods like GetTags. But what is the input parameter tagIds? The return is a object. But the Media Client has no class Tags.
I also searched google, perhaps already exists a plugin for such a export. But I found nothing.
Can anybody help me?
Best regards
Thomas

I have found a solution (psedbtools).

How to develop a Library for Windows Phone 8.1?

Hello guys!
I'm a quite new developer in this topic, I have never created a Library and right now, I need to create a library using this project of C because the normal OCRs cannot recognize 7 segments display:
https://www.unix-ag.uni-kl.de/~auerswal/ssocr/
Last year, I used a library for SQLite (in the beginning it didn't have a Nuget package) and you must add a C++ project to execute SQLite code in WP8. I hope someone might give me an idea where to read and help me with this project. Thanks a lot
for your worthy knowledge.
Federico Navarrete

I need to use a special OCR that detects 7 Segments Displays. I have been reading during the week and I discovered that the most similar project is this one:
Seven Segment Optical Character Recognition
However it's a C project not a C# or VB and I must create a special library (or project) to integrate with my Windows Phone App. As I said before last year I used this article:
How to use SQLite in Windows Phone
And in the beginning it was just a C++ project that you must add to manipulate SQLite. So, I think I should create something like that for migrate those libraries and later integrate with my project but I have never worked with this kind of libraries
or create C/C++ libraries that finally will work with a C# App. Thanks for your time.

How do I... Set up an entirely seperate iTunes library for my kids?

I would like to set up an entirely separate iTunes library for my kids on the pc which currently has one iTunes library and everything we own collectively in it.
There are some items not suitable for children (explicit music lyrics, "MA" or "R' movies, etc) that I do not want them to have access to. Disregarding the whole "parental control" settings, I would simply like to be able to open iTunes to a library which has only the content I deem acceptable for them so they can arrange their own play lists, sync their devices, etc, with minimal input by me.
Is there any way to do this? If so, How?
PS: I would only be using one iTunes account but would like to be able to drag content from one library to the other. For example, download a purchased movie into the "Master" account but be able to put it in the kid's library also.
i would like an entirely seperate libray, not just a playlist for them.
Thanks!

Hmmm.... Of course I ignored the "causes problems" line and went ahead and set up a 2nd library anyway!
I experimented with a movie (Forbidden Planet).
1st I simply copied it from my original iTunes libray (it was in the "Movies" folder) on my hard drive into the new Library "Itunes1". Of course when I opened iTunes that movie did not appear in the new library (it was totally without any content). So I realized that the movie actually has to be loaded into iTunes. So I dragged it from my old library and dropped it into "Movies" tab with iTunes open with the new library. Success! Just like any other time I import anything.
So then I went into my hard drive and looked at the iTunes1 (the new) folder and the movie is not there! But it plays!. So I realized that the movie stays in my orignal library but is now there twice (). Once as Forbidden Planet and once as Forbidden Planet1 (there is a number "one" after the title).
I also have the one sitting in the iTunes1 library where I dragged it first.
Now, I can't delete any of them as the message "access denied" pops up!
So, the movies are duplicated when they are loaded into a 2nd library?
And they stay in the original library's folder system?
Or did I just do everything wrong from the start? (but the movie plays in both library's!)
Help!

How do I use one library for multiple iPods

I have three girls that recently got iPod nano's. I would like to use only one library for their music etc. How do I do this. when I installed the first one it worked great. Then when I installed the second one it won't recognize the first one. Then when I went back to factory settings on the first and synched her music the second one is not recognized. Help......

Sorry, guess I am not using the "technical lingo". I already had itunes on my computer for a medical review course that I purchased to study for a certification exam. When nano #1 was purchased I hooked it up, registered it, and synched music to it. When my daughter tried to play songs, the songs titles and songs were mixed (song didn't match title). I hooked it up to the computer. It said it needed to be formatted. So I did and reregistered and synced the songs back on. Everything ok. Second nano hooked up, registered, named different name than #1, synched with the music she wanted. Tried to hook up #1 and it didn't recognize the nano. I went to the website and found out how to "find" it on the computer, followed the instructions to find it, and again it had to be "formatted" to have it recognized. I was again able to sync her music. Will I have to do this everytime I try to sync more music? that could be a real pain!
thanks for any help for this sometimes electronically challenged mom.

TS4062 I am completely frazzled! My iPhone 4s says I'm over my GB's so now I can't even delete ANYTHING, not even my texts! also when I try to sync with Itunes it says there is not enough room in the itunes library for me to sync. What do I do now?

I REALLY need help!!! My iPhone 4s is apparently OVER the amount of GB its supposed to have so it now will not even let me delete ANYTHING! Not my texts, apps- to free up space, NOTHING! It keeps kicking me off my email, wont let me get voicemail,see who last called on my "recents", wont let me send or receive text's or even let me change things in my settings. Now when I go to iTunes to sync, so I can try to free up space, iTunes sais there isn't enough space in its library for all my stuff so it WON'T sync either!!! I'm frozen and I have A LOT of VERY important stuff on my phone that I REALLY need! Can anyone tekk me what to do? PLEASE!!!!

First off try and go into your IPhone manually through My Computer and cut photos or anything you can through the device to be able to free space up so that you can continue to do what you want to do with ITunes. This way you will be able to create a backup or do what you have to do to manage your information, photos and texts on your device a little better.

How can I use my itunes library for iphoto slideshow?

how can I use my itunes library for iphoto slideshow?

Here's a possible workaround:
Create the slideshow in Iphoto and add a theme and music.
Install Picasa and it will include the slideshow on it's indexed list.
Upload the slideshow to PicasaWebAlbums and send the link to anyone you wish.
The music and theme is preserved.
Caveat: My playback pictures appear darker than usual but that could be just lousy photography...:)

How do i make a seperate itunes library for an external hard drive?

my brother bought an external hard drive to have his own itunes library. We attemted to download the program into the ex. hard drive. but what it did was transfer all my music to the ex. hard drive. So we undid it, and now its back on my computer. So what can i do to have a seperate library for the external hard drive?
Windows XP

Choose Go to Folder from the Finder's Go menu, provide ~/Music/ as the path, drag the entire iTunes library to the external drive, and if desired, then to the iMac's internal one. If you put it in a different location than the default, launch iTunes with the Option key held down and point it there.
If the library contains rented movies, those won't play on a different computer.

External HD as iTunes library for 2+ Macs

Hello,
I am looking for the best way for my external hard drive to serve as the iTunes library for both my work iMac and my personal MacBook.
If possible I want to be able to add music (from CD - yes I still like to support my local record shop - and from iTunes Store) to the library while using one computer, and have that automatically show up in iTunes when I open it on the other computer. Can this be done without having to select the new files and click "Add to library" every single time I open my other computer's iTunes? I sometimes go long periods without using one of my computers and add lots of music to my library, so it's tough to remember exactly what is new. If that can't be automatic, is there an easy way to search for the new files that aren't yet visible on the iTunes screen?
So basically I want to know if my all of the content and brains of my iTunes can be on an external HD that can be used with multiple computers, and each computer I use simply serves as a controller for that iTunes library and scans for updates each time it opens. I'm not interested in options that involve using a cloud/match/sharing service, as I am often without internet service.
Thanks so much!

Quit iTunes.
Drag the iTunes folder in the home folder to the trash but do NOT empty it yet.
Start iTunes and see if the songs play. No need to hold the Option key.
If everything works (play a song), you can empty the trash.
I rather not have to hit option everytime i load itunes
No need. iTunes will use the last library opened.
In order to access the music and library, you need to have the external connected and ready BEFORE you launch iTunes, else it will go back to the default location (Users/username/music) and create a new iTunes folder.
If this happens, simply hold the Option key again and choose the external drive.
You can use this drive on the other computer.
Simply plug it in and start iTunes while holding the Option key. This only needs to be done the first time unless you start iTunes with the external drive not attached then do as above.

Use 1 itunes library for multiple user accounts

Is there a way to use 1 library for multi-user accounts on mac osx? I have 4 iphones and was previously using the main account only. I'm getting tired of having everyones contact lists downloaded into my main phone. I can't seem to figure out how to sync the music to the same library.

Hi There,
I sync 2 iphones with the same library, and to stop the other iphones contacts adding to mine I have two groups in the address book, one has my contacts in and the other my friends. I then just sync the appropriate address book in the info pane when the iphone is plugged in.
Hope this helps.

Using single iTunes library for multiple computers

With the new Airport Disk utility, can I attach an external hard drive with my iTunes library and have multiple computers point to that library as the library for each?

just to clarify...
Use ONE computer and ONE COMPUTER ONLY for purchasing / adding new content to the 'master' iTunes library area. Use ANY OTHER COMPUTER that's looking at that 'master' iTunes library for reading (playing back).
Yes. If you can enforce it by "persuasion", not software
Would there be a conflict if someone rates songs from other computers etc?
Yes. If they both rate at the same time.

One Itunes library for Ipod and touch

I have a 5th generation Ipod and plan on upgrading to the Ipod touch. Can I keep my one itunes library for both devices or does each device have to have its own itunes account/library?

You can't do that.
And before you decide to store any music that you own on a computer at work, talk to your IT department. Many organizations do not permit it for legal reasons. Standard policies are that anything stored on company owned computers is the property of the company. It could not be legally stored on their machines unless you transfer the licenses and all copies, physical and digital, to the company, meaning you no longer own the music. If they were to be audited and could not prove that they own the music, they would be subject to copyright violation penalties. Just use your iPod when you're at the office if you want to listen to music.

Having one iTunes music library for multiple computers via TimeCapsule

Hi there,
I'm just wondering how to best set-up my iTunes library. I want the library on my TimeCapsule wireless hard drive, and to be able to set this as the library for multiple computers at home. It's a waste of space to have duplicate libraries on both computers.I had this working with an earlier version of iTunes, but its not working now.
I also want to know how I can get the wireless device to fire up simply by pressing the iTunes icon. If I do this without, iTunes says it can't find the library.
Thanks.

Frank, yes. Only one library of the songs and content if it's stuff from the Music Store.
If the music is your own CD rips, then you can put all the music on a central server and have all the computers connect in on your home network.
You do NOT set your iTunes to share their libraries, or look for shared libraries, you manually do the drag-and-drop with your networked music folder into the iTunes library window and each copy of iTunes behaves as if the network volume is it's own.
The only shortcoming to this is if you add music with one machine, the others will NOT have the new songs added to their own library lists unless you drag and drop the songs into the iTunes library manually for each computer.
I have enough music that I have broken down the library list into five folders, A-E, F-J, K-O, P-T, and U-Z. When I add new songs, the folders they're in will be added at the root Music Library folder level, so I can refresh the libraries with the new music THEN manually file it into one of those five correct folders.
This is what my network library looks like:
http://home.comcast.net/~foodandart/Network%20Library.jpg - you can see that I haven't added the Clapton, BBC, Roxy Music, etc, to the library lists for the entire house.
The G4 frankenbeast computer in our living room, is the media server for the house and has the stereo system rigged through it and is used to rip vinyl and watch the video. I still have to refresh the libraries in my husband's laptop, and on my main internet computer, so those albums haven't been filed yet.
Of course the caveat here is that I haven't a single item that's purchased through the Music Store and thusly locked down, since I rip my own LP's and CD's, so everything is much more flexible in how I can handle it.
Deb.
