Opto 22 manufactures powerful and easy to use hardware and software products that allows measurement and control of all kinds of electrical, mechanical, and electronic devices and machines.

OPTO 22 IOT products enable industry to look after all types of systems and devices remotely View

Opto 22 PAC controllers, I/O (input and output modules), solid-state relays, and software are used for industrial automation, remote monitoring, data acquisition, and machine-to-machine (M2M) applications.

OPTO 22 has the best HMI product on the market groov

OPTO 22 products make it possible for you to use your normal business networks and computer systems to monitor, control, and get data from all the devices and machines that are important to your business, on the production floor or even more remotely.

OPTO 22 products translate the data between computers and other machines. This translation works easily and inexpensively because Opto 22 designed products to run on non-proprietary communication standards like Ethernet and the Internet Protocol (IP).

Also BACnet, OPC, Modbus, dnp, EthernetIP etc

You will find if you are building PAC based solutions, in almost all cases OPTO 22 will the lowest cost and the most flexible of all current solutions on the market. And of course you get OPTO 22 legendary isolation and tough I/O.

Ask for a quote before you run off and buy some companies PAC system that doesn't have the long experience OPTO 22 has (since 1972).

Linear and Rotary Measurement



Unimeasure Products

MasTec has distributed Unimeasure for many many years.

UniMeasure manufactures a broad line of flexible braided wire actuated linear position and linear velocity transducers. Often referred to as a string pot, a yo-yo pot, a draw wire transducer, a linear position transducer, or a cable extension transducer, the device has proven to be an attractive approach for a multitude of applications in many different industries.

With relatively non-critical alignment requirements, compact size, and ease of installation, wire actuated transducers are the linear position measurement system of choice in applications as diverse as bone densitometers in the medical industry, crash testing in the automobile industry, pump jacks in the crude oil extraction industry and irrigation and flood control in the water management industry.

With a variety of available electrical outputs that include uni or bipolar voltage, 4 to 20 mA current and Encoded digital, UniMeasure linear displacement transducer products provide an extremely cost effective method for linear position and velocity feedback.

Three LabVIEW Books
"Three Methods to program more effectively in LabVIEW"

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.

The key structure used is a cluster that all the programs constants are placed inside and saving that cluster to a file.

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.

All 3 books are expansive, yet very simple and this information is not often seen in other LabVIEW information at this detail.

Using these methods will simplify and establish design development plus stabilise your programs. It even make installs easier. Updating and expanding programs then follows a standard pattern already in the program design.

Also this method delineates Public and Private data clearly.

Once you have built a program using this LCOP method, if at any point you want to add or delete constants to any of your established components, maybe just add one more constant or truly expand the calibration to include a whole new sensor set or add more paths etc, all that is required is just expanding the type def for the constant data clusters and make the new entries. These entries can be any data type or grahical data type. Once this new type def cluster is saved, it will also automatically appear in the Constant Data Editor TAB Selector Open the Editor, enter your new data into the new constants and then save the new Cluster Constants.

So only one diagram programming step is required, adjusting the Type Def Cluster. Next time the program re/start, the expanded constant cluster with the new data will automatically appear in that section of the program. The wire from the configuration file read will now contain the new constants.

You do not have to add or change anything in the diagram to make this change or addition happen. The program automatically knows the shape and structure of the new cluster constant. This is acheived by using a local variable as the type on the Unflatten from string VI. That local variable used to give the shape to the data wire, is cloned from the Cluster Constant directly so will expand and contract automatically as changes in the cluster constants data and types are made.

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

MasTec has several large projects on its books, spread out over about 3 years. There are gaps in this schedule.

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

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.

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.

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 for succession in early 2017.
