Hi.
I use shared variables on several projects on different nodes. On some of them, after rebooting the OS, the variables restore their value (as it should be), on others this does not happen. I use Windows 10 and approximately the same setting. Does anyone know where I can search in the OS settings or LabVIEW to get predicted DSC behavior after rebooting the OS.
Sincerely, Vitaly.

View File Plasmionique Modbus Master
This package contains the Plasmionique Modbus Master library for LabVIEW.
It supports RTU, ASCII and TCP modes with the following function codes:
0x01 - Read Coils
0x02 - Read Discrete Inputs
0x03 - Read Holding Registers
0x04 - Read Input Registers
0x05 - Write Single Coil
0x06 - Write Single Register
0x07 - Read Exception Status
0x0F - Write Multiple Coils
0x10 - Write Multiple Registers
0x16 - Mask Write Register
0x17 - Read/Write Multiple Registers
0x2B/0x0E - Read Device Identification
Other features include:
- Sharing a COM port across multiple Modbus sessions using VISA locks (10 second timeout).
- Sharing a Modbus session across multiple communication loops.
- TCP transaction ID handling to ensure that requests and responses are matched up correctly in case responses are received out of order.
- Modbus Comm Tester, available through the "Tools->Plasmionique" menu, for testing communication with a slave device without writing any code. 
- Detailed help document available through the "Help->Plasmionique" menu.
Examples are included in "<LabVIEW>\examples\Plasmionique\MB Master\":
MB_Master Comm Tester.vi: Demonstrates usage of API to open/close connection and communicate with a Modbus slave device. MB_Master Multiple Sessions.vi: Demonstrates usage of API to open concurrent Modbus sessions. MB_Master Simple Serial.vi: Demonstrates polling of a single input register over serial line. Download a copy of the user guide here: MB_Master - User Guide.pdf
Note that Version 1.3.4 of this library has been certified compatible with LabVIEW and has been released on the LabVIEW Tools Network: http://sine.ni.com/nips/cds/view/p/lang/en/nid/214230
The most recent version of this library will always be released on LAVA first before going through NI's certification process.

Overview
In order to quickly and efficiently prepare source for distribution, a build system was necessary to abstract away the conversion of source into the different types of deliverables (VIPackages, Executables, dlls, ect) as well as abstract away the build order of our software hierarchy.
Many have undertaken to solve this problem. I don't claim to have created a silver bullet. But I do hope that the system I've put together (and am releasing as open source) will act as a starting point for you to extend and customize to meet your needs. I've endeavored to employ good software development principles including separation of concerns, and the SMoRES principles.
 
I'll be the first to volunteer that it isn't perfect and as always, our best software is constantly a work in progress. However, I believe the build system is at a stage to be at least moderately helpful to a handful of people in our community. 
 
Description
 
The Application's UI
The UI is designed to guide someone through the build process, allowing them to select what components or exports they would like to build, if and how they would like to be notified about the build, auto submission options, and source code control. I've attached a small video titled "Build UI Demo.mp4" below.
UML and APIs
All UML and API documentation are included in the Word document per released zip file
 
 
Software Requirements
LabVIEW 2017
NI Application Builder
VI Package Manager Pro
Other dependencies are listed in the Instructions per zip file.
 
UML Overview
As of 1.4.0-58 the UML looks like:

Release Notes
1.4.0-123 (Component Builder 1.4.0-123.zip)
Added new NI Package Manager API Added new NI Package Manager BuildSpec Utils  Added procedure and documentation for the component template and its anatomy  
1.4.0-113 (Component Builder 1.4.0-113.zip)
Added documentation for the SCC API  
1.4.0-111 (Component Builder 1.4.0-111.zip)
 
1.4.0-99 (Component Builder 1.4.0-99.zip)
Added a few new P4 API functions allowing the creation of a session if a user is already logged it.  Added Log in and log out tests to the test suite.  Adding new function to tag all p4 paths in a label with the label. Resolving the input path to a p4 depot path Adding quotes around p4 paths.
   
1.4.0-91 (Component Builder 1.4.0-91.zip)
The refactor of the LabVIEW SCC API is complete and the build process is linked to the new install location. The LabVIEW SCC API can now be used independently of the Component Build process.  I've included a test suite for the P4 implementation of the SCC API. It assumes that you have checked in the two files in the "Build Instructions\LabVIEW SCC API\Test Suite\Tests\Test Dir" into perforce.  
1.4.0-85 (Component Builder 1.4.0-85.zip)
This is a major refactor in the SCC API. I've modeled the p4 label with a new api. This release is primarily as an intermediary release. I intend on breaking SCC out of the component builder into its own separate component in the next release. 1.4.0-81 (Component Builder 1.4.0-81.zip)
Created a "proxy" api for VI Package manager interactions. Sometimes the VI Package manager api would hang. So I now call by reference and will kill and restart VIPM if it doesn't respond in time.   
1.4.0-75 (Component Builder 1.4.0-75.zip )
Fixed reference counting for executable builds.   
1.4.0-73 (Component Builder 1.4.0-73.zip)
In the case where a user has specifically unchecked "auto increment", the build process will auto increment the build. Builds must be auto incremented.  I've released a new build of the container that has a minor bug fix. Added file utility tools to aid with using "net use" to move and copy files across the network.  
 
1.4.0-59 (Component Builder 1.4.0-59.zip)
Minor spelling error in component template: "componet". Added documentation for the Custom Install Step Launcher. Added build instructions for Custom Install Step Launcher.  
1.4.0-58 (Component_Builder_1.4.0-58.zip)
Added the ability to export NI-Source Distributions, NI-Executables, NI-Insatllers, and NSIS Installers Released a template component that exports an NI Package and VI Package including step by step instructions Released "Custom Install Step Launcher" to execute VIs as pre install, post install and post install all actions for NI Packages. Released comprehensive documentation included in the zip file. Component_Builder_5_31_2018.zip
