[LVTN] Messenger Library

Tue, 27 Nov 2012 11:50:05 +0000

Messenger Library

An extensive library for passing messages between parallel processes. Generalizes the communication method, allowing the message sender to use the method provided by the receiver. Supported communication methods include wrappings of simple queues, user events, and notifiers, as well a more complex channels such as a TCP server and client. In addition, one can configure simple forwarding addresses (“Observers"), which can send messages to multiple destinations, optionally with modifications such as adding a prefix to the message label, relabelling, or substituting a different message.

Communication patterns supported include request-reply (asynchronous or synchronous), where the reply is sent to a "reply address" attached to the request, and register-notify, where one process sends a registration message to another in order to subscribe to a series of updates. Also supports scatter-gather, the gathering of replies from multiple senders into an array of messages.

An option framework for dynamically-launched VI "actors" is also provided, including example templates, which can be accessed via the Tools menu (from an open Project, select Tools>>Messenger Library>>Create Actor from Template..). An "Actor Manager" debug tool is also installed under the Tools menu. Please note that this package has nothing directly to do with the NI Actor Framework (other than both packages are influenced by the Actor Model).

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 "\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.

UI Tools

UI Tools v1.4.0

Author:François Normandin

Contact Info: Contact via PM on www.lavag.org

LabVIEW Versions:

Created and tested with LabVIEW 2012

Dependencies:

OpenG Application Control Library >= 4.1.0.7
OpenG Array Library >= 4.1.1.14
OpenG File Library >= 4.0.1.22
OpenG LabVIEW Data Library >= 4.2.0.21
OpenG String Library >= 4.1.0.12
LAVA Palette >= 1.0.0.1

Description:

This package contains tools for designing user interfaces.

A first palette helps create special effects using transparency of front panel. Using them allows to quickly create fade-ins or outs using linear or exponential variation of the intensity.
A second palette contains VIs to calculate the position of GObjects for many purposes like alignment, snap, mouse follow, etc.
A third palette contains VIs to create dialog boxes based on class instances. "Simple Error Dialog" and "Simple Selection List" are featured with or without backrground blackening effect.
A fourth palette includes some VIs to move objects programmatically on the front panel, using a basic deceleration algorithm to provide an impression of a smooth movement.

The packaged VIs are all namespaced using a suffix “__lava_lib_ui_tools” which should not conflict with any of your own code.

Includes:

Front Panel Transparency (Fade In & Fade Out)
Utilities (Alignment, Snap)
Dialog (OOP based, extensible)
Engine (Beta) for object movement

Instructions:

This package is distributed on the LabVIEW Tools Network (version 1.3) and updates are on LAVA (1.4). It can be installed directly in the addon folder of any LabVIEW version from 2012 to now. The addon installs automatically under the LAVA palette of the addon submenu.

License:

Distributed under the BSD license.

Tell me how to use Modus Master Library

Tue, 08 May 2018 06:56:29 +0000

Hi, Nice to meet you.

I'd like to use "Write Single Register.vi" by RTU mode.

But I don't know how to input Value(U16).

http://modbus.org/docs/PI_MBUS_300.pdf

For example, like a query in above link page28, Figure 7.

In this case, How can I input value ?

Sincerely,

Canko

[LVTN] Code Capture Tool

Fri, 03 Jul 2009 06:12:14 +0000

Name: Code Capture Tool

Submitter: Ton Plomp

LabVIEW Version: 2009

License Type: BSD (Most common)

The Code Capture tool allows you easily create screenshots of you LabVIEW code for use in documentation, web-sites, wikis, emails.

This tool provides an API for creating images of LabVIEW code as well a GUI for easy capturing and use of code.

Further info is provided in the help-screen (F1) of the program.

For the latest version visit the Code Repository

For the latest version of the source code, visit SourceForge

For more info, visit the LabVIEW wiki with the documenation.

A series of videos is available on screencast: Code Capture Tool

Installation

============

To install the Code Capture Tool, run the 'Install Code Capture Tool.vi' in the LabVIEW version of your choice, or use the OGP file in conjunction with VIPM.

A wizard will guide you through the installation procedure.

Usage

============

After installing and restarting LabVIEW, you can open the Code Capture Tool via the 'Tools' menu to capture an image of the current VI.

For more info open the About screen of the GUI.

Uninstalling

============

To remove the Code Capture Tool from your LabVIEW installation remove the following files in your LabVIEW folder:

Project\Code Capture Tool.vi

user.lib\CCT.mnu

And the following folder:

user.lib\_Code Capture Tool

In your LabVIEW data folder (in Windows, this is normally: My documents\LabVIEW Data) is a configuration file called Code Capture Tool.ini, which can be removed at any moment. However this file can be shared between mulitple versions of LabVIEW, I recommand you to use a special LabVIEW data folder for each LabVIEW version.

Contact

============

Comments, bugs and thank yous can be expressed to the NI Forums community , and on the LAVA community at the CCT discussion thread.
