  Is it possible for someone to post a new link to this library?

  Best regards

  I just put "ftp.ni.com/pub/devzone/epd/nimodbus121.zip" in the address of my browser and downloaded correctly.

• I use the MODBUS library and can receive data, but I can send it very well?

  Hello

  I use the Modbus Library to communicate with a VFD to control a fan. I use the master write and read vi. I can write data to the drive mechanism and get the fan to do what I want. The VFD is supposed to send a package of confirmation after I told him to do something and I can also read its records. When debugging the VI it shows that the problem is that the buffer always reads zero and the VI timesout. If I look at the USB adapter lights to RS 485, I use to interface with the drive mechanism, I see that the flashes of light RX immediately after I send a message. So I should have something in the buffer. Does anyone have any suggestions?

  OK, here's what has happened to those who have this problem. In the series Receive.vi MB The bytes to the Port of property node has been reading 0 even if there was something in the buffer. Executing the program was then stuck in a loop until it expired and never went to read anything of serial port buffer. I didn't spend too much time wondering why that VI has not worked and created my own. Within a period appropriate after writing to the serial port, I used the same bytes to the Port property node and was able to get the exact number of bytes to the stream and then VISA vi the number of bytes to read. I received the message of the right answer and everything seemed good. But of course that NO! Then I experimented with different speeds of writing to the drive mechanism to get the fan to operate at different speeds. I found a small range of speeds where I get no response to the VFD, either in operation or by sending me a response packet. After a while, I found that there is a mistake in the LRC-8 code in the MODBUS library OR. It does not prescribe that the LRC will be a two-character value. So if your LRC is proving to be a single character such as F value (which should be 0F) you get an incomplete MODBUS message. This has been easily corrected in the vi LRC8 saying "number in hexadecimal string" vi to produce output with a minimum width of two. Then everything worked fine. Moral of the story, it's the MODBUS library is awkward.

• Several Modbus with shared serial port

  I know that Lookout lets do you cool things like have several protocols series that share the same serial port hardware.

  I asked where I might like Lookout to simulate a network of Modbus Devices for some tests. In this case, I want to implement multiple Modbus slave, all with different node addresses Modbus objects and have all listen to the same serial port. Would this be possible? Each received Modbus message will include the number of slaves in there. Multiple objects can listen on port and only the selected one respond?

  Thank you

  Max

  Yes, slave modbus Lookout can work this way.

  But the ethernet mode does not support.

• How to create the shared library for linux real-time target in labVIEW Windows?

  I use myRIO running linux in real time. In my project, I need to pack some C code, so I tried the node library function call.

  I know that I should use the tools compile cross - compile linux on Eclipse to compile c code in linux .so library. But the problem is that call library function node does not recognize the .so file because my labVIEW runs on a Windows PC.

  What should I do to fix and how to combine C code with labVIEW during programming for devices shipped as myRIO?

  Basically, you must also create a Windows DLL that exports the same functions. These functions can be empty stubs if you do not want to run the code correctly on Windows, otherwise you will need to consider how to implement the equivalent functionality on the Windows API.

  Then you can write in your node library call as the name of the library ". "*" and the name of the shared library Windows ".dll" while the Linux version is called "name of your library > .so". LabVIEW will replace the * after the comma in the name of library with everything that is the preferred extension shared library for the platform it is running on and therefore load the right shared library.

  Alternatively you can wrap call all the nodes of the library in a structure that contains the node library in the case of Linux RT and all what you want to run on other platforms in the case of default or a case of specific platform, call the conditional compilation.

• ICloud using photo library for the first time

  I am considering switching to iCloud photo library for the first time - mainly so I'll be able to use the new functionality of memories in iOS 10. However, I have quite a large library of Photos on my Mac and I'm worried about the mistakes of synchronization, bugs and any damage my irreplaceable photos. I have a Time Machine backup, but each backup on which generally only lasts a week or so, and with a large library of errors can take some time to appear. Should I be worried? Are there precautions I need to take?

  In view of all the people who use it, there are very few messages on issues. Since you have a backup, you can still recover. You can consider to get a 2nd external and make a copy of your photo library in order to have 2 backups. Depending on the size of your library, you may need to purchase additional iCloud storage as free storage space is 5 GB. With a large number of photos, it will take much time to complete the synchronization. Some people have posted their s took 2 to 4 weeks. Our respective synchronization went well and we had no problem.

• HP ZBook 15 G2: I can't find driver for Serial Port PCI

  After re-installation, my HP ZBook 15 G2 is missing the driver for "PCI Serial Port (COM5)".

  This unit has the following ID: VEN_8086 DEV_8C3D

  I installed all the drivers for chipset for the HP ZBook 15 G2.

  Where can I find the driver for this device?

  Hello:

  You need this driver.  If the driver will automatically install the driver for serial port, and then manually install the device by navigating to the folder of the driver that was created when you ran the file.

  This file will be located in C:\SWSetup\sp68428.  Make sure that the include subfolders is selected and the driver should install.  Then restart.

• Transfer Mac Air Aperture library for iMac.

  Transfer Mac Air Aperture library for iMac. I placed the library is on an external HD; connected to the iMac; switched to the libraries on the ext HD; go to file > import > library-however the dialog box has the desired gray library. It shows another Aperture library (the iMac original Aperture library that I've got on the same post HD for the trip).

  Any thoughts?

  

  Could solve the problem now?  Usually only the library that is currently open in Aperture will be grayed out. your screenshot looks you had currently open "Library Aperture 2" opening and could open "Aperture library.

  Try again to move to the correct library that you want to import.

• Programming of the digital I/o pins on the NOR myRIO-9100 for serial communication

  I use NEITHER myRIO for my robot and I want to use four reading of the distance sensors that communicate via the serial port. But the myRIO has only two UART ports on board so I was wondering if there is a way to program the digital pins use for serial communication. Any help appreciated.

  It is possible.  Here is an example that I could find.

• Create a shared library for NI Linux real-time

  I need to build a shared library for NI Linux time real (.so) which corresponds to a shared library, which I create on Windows (.dll).

  I have the C code that needs to call a function of VI. On Windows, I have a project that allows me to create and build a "Shared Library (DLL)", but I don't see the same option available in a real-time project targeting the cRIO-9068. Am I missing something, or is it not still possible?

  Hi Wayne,

  Using LabVIEW VIs in other programming only possible through dll environments. In LabVIEW there are options for creating libraries and source, but these distributions will be accessible in LabVIEW and not in other programming environments.

• I have a Leica LR but my creative cloud annual subscription has expired, my Lightroom my LR library for 2015 and beyond now has a question mark and I can't open pictures

  I have a subscription valid and active Leica camera.

  How can I get Adobe to recognize? My creative cloud has expired. I'm frozen out of my photo library

  Using the redemption code Leica I downloaded successfully updated day to day LR 6 but my LR library for 2015 and beyond now has a question mark, and I can't open the images.

  Any suggestions?

  Is this something that Adobe has to rectify?

  Thank you

  John

  The question mark has nothing to do with your subscription at the end. The question mark on your records indicates that Lightroom cannot find the photos, because they have been moved or renamed, or delete outside of Lightroom. The instructions to fix it are: Adobe Lightroom - find folders and files moved or missing
