The lead picture this month is really a logger and a recorder with a very nice touch front end.

It has almost everything.

Protective Rubber Boot - Comes with Hard carrying case
Benchtop or Wall Mount Enclosure Design

Now that is a Logger.

There are several NZ operators that have these already.

This is the new Industrial Tool for Process work and for site and field research. It is all done for you.


However if you are in the Transport business this is not the logger, the best is from Senonics, largest Supply of toss in the freight loggers.


They invented the Lipstick Taser oops Logger and now have such a broad range of Loggers andMonitors, right out to SMS and Wifi Loggers. Use once Loggers for Pharma


They make minature scientific loggers with LCD charts and several other sophisicated versions that drive sensors.


They make super loggers, that is hugh channel count loggers and are used mainly in Research work for monitoring at high sample rates. So loads of memory.


They make loggers, that run in PCs. So canned software that turns the PC into a powerful logger without the programming. Juist connect an MCC DAQ module on the USB port and configure and it is done.


They make Zigbe loggers, so a cluser of loggers.

Packet Power

They make AC Power Usage Loggers and monitors. Plug into the power cable to the device and measure and logger.


They have a large range of Industrial and commercial loggers that run on Modbus or Wireless


They make environmental loggers.

MasTec stocks the most popular loggers so you can be collecting temperaure and humidity data very quickly.

  LabVIEW Books   
Five PDF Books
How to program more effectively in LabVIEW

A 6th Book is planned to show how to include Editable Operator Messaging Inside State engines from files loaded at runtime.

The current 5 books introduce a more thorough development of LCOP - LabVIEW Component Object Programming methods.

Recently an early legacy piece of software built using these techniques was upgraded to a new DAQ system using Distributed IO on Modbus TCP from the older USB DAQ

This was an extensive upgrade plus many new features were added.

Report :-

This technique makes for an orderly upgrade, that is easy due to the design methods used.

This method makes extensive use of Front Panel TABs to expose different aspects of the Application as Tab groups, In each Tab there are Clusters as Type Defs and the sub Apps are driven by Enums as Type Def Verbs inside simple state engines.

It has a built in Cluster Editor that runs either in the Program that allows remote adjustment of programs configuration files.

Using LCOP methods will simplify and establish design development plus stabilise your programs. It even make installs and maintenance easier.

Updating and expanding programs then follows a standard pattern already in the program design.

This method delineates Public and Private data clearly.

This is critical for Component Design and for low coupling and best Cohension.

Book 1 "Hidden Data",

that is, cleaning up LV Program's by Removing Constants from Diagrams and putting them in Configuration Files for Loading at runtime.

This method does not use ini files but a far more robust LabVIEW centric method, not seen in other literature. It also cleans up Diagrams and Self Documents.

Book 2 "Abstraction",

that is, removing complexity in the top layer of a LabVIEW diagram by building Abstracted Message Driven LV Components.

This shows how to build Message driven (Test Verbs) Abstracted named (noun) State Engine Components that are safe & robust. It also leads to better cohension of course and no/low coupling.

Book 3 "Real Time Cluster Constants Editor"

that is, Removed Diagram Constants that are loaded at Run Time from a config file, can now be edited, in situ, inside the Program /or its Component while it runs, allowing tuning of programs in Real Time.

Changes made to the Constants by the editor can also be saved back into their original configuration files at run time. This addition of the Real Time Editor removes the need to exit a component or program to edit constants.

Book 4 "Low Frequency Real Time Control",

is about how to use USB DAQ, DIO and DAC to control an Hydraulic RAM for Testing a UUT.

It is a close look at how to use State Engine for Control.

Simple but useful for anyone wanting to do closed loop control.

It embodies many of the LCOP methods discussed in the other three books.

Book 5 "An Off Line Constant Cluster and Calibration Editor"

For Editing, Loading and Saving Cluster Constants" and also built in into the editor "Adjust Calibration and System Data" off Line for easing commissioning. Plus more helpful bits.

This includes a section on setting up all Paths for an application as a large Cluster Constant, again easing commissioning, Typically a large Application will have in excess of 30 Paths to manage.

MasTec Training
"LabVIEW for Everyone"

MasTec recently under took a 4 day Training course for 15 Academics, (Professors and Grad Students), at one of Oceania's largest universities.

The focus was on getting students to the point where they can undetake projects by the end of the course. A big ask. However, the focus was not on how to use all the bits inside LabVIEW to make software but the development of strategies to allow projects to be undertaken.

The MasTec Instructor has trained all over the globe and has taught over 2000 students.

He will also come to your site and do training with your LabVIEW team, using traditional or these new LabVIEW methods MasTec has developed.

MasTec Projects

Over the last year MasTec has completed 6 major projects in sites through out NZ. Several hundred hours of programming work has been completed, as well as many hundreds of hours of commissioning, site management, and installation.

All these projects involved LabVIEW at the core. However, many of these projects also include PACs, PLCs, Process Controllers, with peripherals like Servos, Actuators, VSDs, Water measurement and control, Hydraulic Control and other real world systems.

MasTec has several large projects on its books, spread out over about 3-4 years.

There are gaps in this schedule.

Many sites still run XP and Win 7 for their LABs and Production areas. MasTec is still undertaking new projects in legacy LV 6.1 /7.1/8.2 and 8.6 systems.

Major new projects are still undetaken in LabVIEW 7.1 that run in Windows 7 32 Bit OS, very successfully. LabVIEW 7.1 is still (in our opinion) the best LabVIEW ever released. Fast, efficient and stable. Win 7 32 bit OS will be available for some time. Most large corporations are still running Win 7 due to its excellent stability and IT staffs familiarity and history.

However, other projects using from LabVIEW 2010 up to the present version of 2015 SP1, which is good, but very processor hungry and much slower to develop in. We only recommend I7s CPUs with this software with SSDs for the OS and LV.

Announcement >>> Opportunity

The MD of MasTec has recently decided it is time to realign his life after 50 years of technology, to go horse riding with his wife and dogs Polly, Lilly and newly arrived Freddie.

If you have an interest in owning this important technology company, now is the time to act and start communcation.
