Brilliant SCADA System that failed

Sunday, September 19th, 2010

A friend of mine shared an article about software failures. it’s a good stuff to read, where we can avoid some mistakes that previously been made by software developers. there is a SCADA software there – some of the problems that I’ve been encountered too in my life. check this out:

http://images.nakedmaya.com/Troll-Link1-sm.jpgNet-Herald – a monitoring application for water supply companies. It was a complex client server application that would receive monitoring data from specialized hardware and store that data inside a SQL database. The client displays that data in different graphs, provides printable reports or sends alarm messages via SMS if a monitored value is not within its specified limits. I developed Net-Herald as a perfect fit for that specialized hardware that is provided by a local manufacturer. That way, so I hoped, I could profit from their sales leads and would find a smoother way into these water supply companies. The downside of course, was that my software would only work with their hardware. (more…)

OPC Training Institute Selects Softing Products for OPC & DCOM Training

Saturday, May 17th, 2008




opcti logoEdmonton, Alberta – The OPC Training Institute, a worldwide technology-training provider, announced today that it has selected Softing’s OPC Tunnel product as a teaching tool in their hands-on OPC training workshops.

OPC technology is a global industrial connectivity standard that enables process control and manufacturing applications to communicate with each other using an interoperable, reliable, and secure connection. Interoperability is apparent due to support by over 3,000 companies with well over 15,000 unique OPC applications. As a result, most work environments host a multitude of applications created by a variety of vendors. Historically, vendor-hosted training opportunities generally focus on proprietary solutions only.

Softing, a world leader in providing OPC technology, was selected by the OPC Training Institute because of their strong commitment to provide advanced OPC technology. Softing is a Charter Member of the OPC Foundation and participates regularly in OPC Foundation Interoperability sessions. In addition, Softing has authored the OPC industry popular “OPC Book” now entering its 4th revised edition.

“We fully endorse the OPC Training Institute as it is an excellent approach to introducing OPC technology to a global industry,” says Jürgen Lange, Product Marketing Manager at Softing. “They are staffed with OPC experts that readily convey the technology by combining their know-how with real-life examples.”

“We choose Softing’s OPC Tunnel product for two reasons,” says Randy Kondor, President of the OPC Training Institute. “First, Softing is a reputable international company headquartered in Europe. We seek to partner with world-class companies that have local representation in the regions where we offer OPC training. Second, Softing’s certified OPC Tunnel is a field-proven product for applications that require high-performance and data security.”

The OPC Training Institute’s Certified OPC Professional designation involves four levels of training. Softing’s OPC Tunnel application is demonstrated in “Level 1: OPC and DCOM Diagnostics”. OPC Tunneling products, such as Softing OPC Tunnel, will be used in the classroom to demonstrate how to reduce the reliance on Microsoft’s DCOM technology while at the same time optimizing the OPC technology communication standard.

The OPC Training Institute is supported by many OPC Foundation members all with the goal to educate automation professionals on the use of OPC technology.

Earth’s Worst Software Bugs in History

Wednesday, May 7th, 2008

Last month automaker Toyota announced a recall of 160,000 of its Prius hybrid vehicles following reports of vehicle warning lights illuminating for no reason, and cars’ gasoline engines stalling unexpectedly. But unlike the large-scale auto recalls of years past, the root of the Prius issue wasn’t a hardware problem — it was a programming error in the smart car’s embedded code. The Prius had a software bug.

With that recall, the Prius joined the ranks of the buggy computer — a club that began in 1945 when engineers found a moth in Panel F, Relay #70 of the Harvard Mark II system.The computer was running a test of its multiplier and adder when the engineers noticed something was wrong. The moth was trapped, removed and taped into the computer’s logbook with the words: “first actual case of a bug being found.”

Sixty years later, computer bugs are still with us, and show no sign of going extinct. As the line between software and hardware blurs, coding errors are increasingly playing tricks on our daily lives. Bugs don’t just inhabit our operating systems and applications — today they lurk within our cell phones and our pacemakers, our power plants and medical equipment. And now, in our cars.

But which are the worst? (more…)
