Protecting Your Plant's Data Against Viruses and Hackers
Security for production network is now a critical issue.
Over the past few years, security for industrial facilities has expanded from simple physical protection to include safeguards for data and networks. In this era of enterprise-wide Internet connectivity, protecting industrial networks has become at least as important as protecting front office systems.
Now that Ethernet and TCP/IP dominate industrial sites, networks are no longer protected by the isolation that came when factory floor communications were handled by an array of dedicated networks that were isolated from the rest of the enterprise. There are many benefits that come with tighter links to the front office and to the outside world using Internet pathways.
But those benefits also bring the need for protection. Security plans must keep hackers and extortionists from attacking the equipment that produces the goods that drive corporate profits... Read more
It's Time to Upgrade Those 10-Year-Old HMIs
Web-based tools make it easy to modernize HMI/SCADA systems and gain many new benefits.
Many systems and components have been upgraded over the past decade, but it's common for a plant's HMI/SCADA systems to remain untouched. Many have become inefficient and ineffective not doing the jobs they could be doing.
Many HMI/SCADA systems were last changed in the late 1990s when fear of Y2K glitches prompted major capital investments. Updating to an optimally configured HMI/SCADA system can bring significant improvements in operations.
“State-of-the-art ten years ago is dinosaur technology at best today,” observes Alan Cone of Siemens Industry. “Today, we are two generations past what was installed during Y2K”... Read more
Safety Systems: To Integrate or Not to Integrate
Combining safety and production can save money, space in many applications.
Safety has always been an important aspect for industrial facilities, but tighter regulations have pushed it even higher in the requirement lists for industrial automation systems. At the same time, the need to maximize efficiency has prompted developers to turn away from architectures that use discrete systems for production and safety functions.
Dedicated safety equipment adds significant cost and complexity. It also takes space, which is becoming more expensive as enterprises use lean manufacturing, just in time and other strategic plans that help them get the most out of every inch of real estate... Read more
