"When we decided to construct a handheld wireless control system for onshore and offshore usage in a classified area, we knew we needed two very unique solutions for our project.

1.  We would be operating in a Class 1 Division 1 area; therefore, we would need a handheld control panel or a PDA rated for the classified area that would 
     be capable of successfully functioning as an HMI device. No small feat,
2.  We would also need an HMI software capable of running the above handheld device with logging and maybe more. This software would also have to
     coordinate with our already designed PLC system from other similar non-wireless or non "classed" systems. Drivers and Communication was soon to be key
     to the development.

As the design process proceeded we also discovered that we needed at least a Class 1 Division 2 wireless PC. This PC was to interact with and control our system, along with the PDA including data logging for pressure and position recording and monitoring purposes.br />
Originally we were unaware of any acceptable products, handheld devices or software capable of handling all aspects of our project.

Eventually, we discovered the solutions to our conceptual problems within the span of a couple of days. We found "Software Horizons, Inc." and their flagship product "Instant HMI".

Located in Massachusetts and specializing in PDA based HMI software and systems they were an obvious starting point for our software implementation.

The next day we discovered a Class 1 Division 1 rated PDA was available for sale in the USA. Upon inception of the project, "Software Horizons, Inc." actually acquired the devices for us, set them up for our unique protocol and even provided the proper conversion devices to allow the correct drivers to seamlessly communicate "Instant HMI" with our PLC based system.

At this stage of the project, our customer now has the luxury of controlling the positions of 16 very high pressure devices from a safe distance in a classed area with precision, dependability and the luxury of position data, pressure data, and other pertinent system data in the palm of his hand.

The customer is also thrilled to have had input on the screen design in conjunction with our staff using the programming and development stage. The system also includes a portable Class 1 Division 2 wireless touch screen PC also equipped with "Instant HMI" for the customer’s use inside of a control room nearby. This PC is equipped with data logging also from Software Horizons.

Previously the operators of this hazardous activity were bound to long runs of cable and air lines as well as other needed lines. Today everything to operate the system is located on a single skid. The control interface action of the system is 100% located on the Class 1 division 2 PDA and the portable Div 2 PC. Everything is wireless.

During this complicated and innovative process "Software Horizons. Inc." was extremely supportive and highly instrumental in all facets of its development and evolution."

"Thank You, Thank You, Thank You

You guys are the best!!!. I followed your e-mail instructions. Flipped the switch (so to speak) and WOW - everything worked exactly as you said it would. I am jumping with joy! Naturally I have found some problems on my end but that's good - now I can move forward. I also plan on changing the Box (thanks for that also!!!!) from input/monitor to just monitor - I'm not sure what I was thinking and I appreciate you pointing that out.

Your support has been outstanding and you have no idea how much of a relief it [is] dealing with people of your caliber. You have certainly made a believer out of me. I have lots of work to do, so I must get busy now. I will stay in touch and let you know how every thing turns out.

"Thank you for everything."
