  • Finding, Measuring and Closing Safety Integrity Gaps

    Plant safety is at or very near the top of almost every manufacturer's operating priority list, often with a stated goal of zero incidents or accidents.

  • Security for Industrial Automation and Control Systems

    The security of industrial automation and control systems becomes increasingly critical as different networks are connected and systems are integrated in a collaborative manufacturing environment. For industrial automation and control systems the potential impact of an attack maybe more serious than for computer systems in general. Users of industrial automation and control systems need to pay correspondingly increased attention to these issues.

  • Securing Your Automation Ethernet Network

    This paper covers the importance of securing automation devices for access internally on an Intranet, or externally over the Internet. Choosing an Ethernet Fieldbus offers the competitive advantage of speed, flexibility and accessibility though steps should be taken to secure automation devices and any associated programming workstations and servers. This paper seeks to educate the Controls Engineer on security strategies, technologies and options available.

  • Hacking the Industrial Network

    Industrial control networks are highly vulnerable to intelligent remote attacks, as well as non-intelligent viruses. With threats to these networks increasing in complexity and scope, decision makers need to take action before it's too late.

  • Building a Bridge to Safety

    This paper examines the benefits and shortfalls of both safety PLCs and configurable safety relays. It also examines a new way of handling safety in industrial automation, "SafetyBridge" technology.

  • Analysis of 3S CoDeSys Security Vulnerabilities for Industrial Control System Professionals

    This White Paper explains:

    • What the 3S CoDeSys vulnerabilities are and what an attacker can do with them
    • How to find out what control/SCADA devices are affected
    • The risks and potential consequences to SCADA and control systems
    • The compensating controls that will help block known attack vectors

    A number of security vulnerabilities in the CoDeSys Control Runtime System were disclosed in January 2012. In October 2012, fully functional attack tools were also released to the general public.

    While CoDeSys is not widely known in the SCADA and ICS field, its product is embedded in many popular PLCs and industrial controllers. Many vendors are potentially vulnerable, and include devices used in all sectors of manufacturing and infrastructure. As a result, there is a risk that criminals or political groups may attempt to exploit them for either financial or ideological gain.

    This White Paper summarizes the currently known facts about these vulnerabilities and associated attack tools. It also provides guidance regarding a number of mitigations and compensating controls that operators of SCADA and ICS systems can take to protect critical operations.

  • Are Your Safety Systems Up to SIS Standards?

    Some 66% of the process control systems now in use globally were installed before publication of today's commonly used safety standards, IEC 61508 and IEC 61511/ISA 84. Here's how to tell if you safety systems are up to snuff.

  • Special Report from Automation Fair 2012 - Smart. Safe. Sustainable.

    The editors of Control and Control Design compiled this special report from the 21st annual Automation Fair event, hosted by Rockwell Automation, in Philadelphia, November 5-8. This interactive PDF includes more than 20 articles documenting highlights ranging from executive keynotes and new product announcements to vertical industry forums and Rockwell Automation Process Solutions User Group and Safety Automation Forum meetings.

  • Remote Emergency Shutdown Device Improves Safety and Performance at Oil Production Platform

    Updated government regulations created a need for a major international oil and gas company to install a direct, real-time communications link at a platform located off the coast of Louisiana in the Gulf of Mexico.

    ENI Petroleum is an Italian multinational oil and gas company with around 78,400 employees at sites in 77 countries. ENI operates in the oil and gas, electricity generation and sales, petrochemicals, oil field services construction and engineering industries. It has oil and natural gas production of almost two million barrels per day, with exploration and production efforts at sites throughout North American, Africa and Asia.

    One of these production locations is an oil well platform called the "Devil's Tower" that is located just off the coast of Louisiana in the Mississippi Canyon region of the Gulf of Mexico. The platform rises 5,610 ft. above the sea bed. Until 2010, it was the deepest production truss spar in the world. Drill ships perform periodic operations within close proximity to subsea pipelines that transport oil and gas to and from the production platform.

    In this white paper, you will learn how a new data concentrator system allowed the control room and drill ships to communicate at a distance of more than 100 km, providing security in case of an incident while avoiding costly shutdowns.

  • Radioactive Isotopes in Process Measurement

    An Objective Look at the Roles of Cesium-137 and Cobalt-60 in Nuclear Measurement Systems for Industrial Processes

    Level and density measurements in process control are performed by a number of technologies. When the process temperature, pressure, or chemistry is an issue, then nuclear measurement systems have the advantage. These are non-invasive to the vessel and unaffected by the process pressures and chemistries.

    Overall, a nuclear measurement system used for process control consists of a gamma energy emitter and detector. An emitter is placed on one side of a vessel to broadcast a beam of energy to the opposite side of the vessel. The detector is placed in the beam on the opposite side of the vessel. The detector will scintillate in the presence of gamma energy and register counts proportional to the field strength. When the process value (level or specific gravity) is low, the detector will register a high number of counts since less gamma energy is blocked by the process material. When the process value is high, more of the gamma energy is blocked which leads to fewer counts.

    The two most common gamma emitters used for level and density process measurements are isotopes of cobalt and cesium. The goal of this article is an objective comparison of the roles of cesium-137 and cobalt-60 in process measurement. This will be accomplished by reviewing the properties of the two materials and then comparing the use of the materials in process measurement.

  • Top Five Missed Opportunities with HMI Alarms and Events

    With any new tech device, whether a cell phone or plant-floor controller, there is inevitably a helpful feature or two you overlooked while reading the manual or taking the introductory tutorial. Although these technological devices still perform their desired, basic functions - discovering an underutilized feature makes you wonder how you ever operated the device without it.

    Interacting with alarms is one of the basic functions your operators expect from their human-machine interface (HMI) software. However, if you're only using the standard alarming functions, you may be missing out on lesser-known features that could help you save time, ease troubleshooting and reduce headaches. The five FactoryTalk Alarms and Events functions listed below are often overlooked and underutilized. See where they fit and if you can find some hidden tools in your plant-floor applications.

  • Maintaining Installations In Hazardous Areas

    Flameproof enclosure (Ex d) and intrinsic safety (Ex i) are very common equipment protection methods in Process Automation. One reason to use Ex d is the amount of energy which could not be provided via Ex i. This disadvantage has gone with the introduction of intrinsically safe, dynamic methods of arc prevention such as DART or Power-i. This white paper shows that when using intrinsic safety, installation, maintenance and inspection costs will be reduced.

    This paper addresses decision makers and professionals responsible for automation systems in hazardous areas. A good understanding of the principles of explosion protection is required.

  • Is Your Current Safety System Compliant With Today's Safety Standards?

    It is estimated that about 66% of the programmable electronic systems (PES) running in the process industry were installed before the publication of today's commonly used safety standards (IEC 61508 and IEC 61511/ISA 84). This paper covers changes brought about by adoption of these standards and what it means to the installed base.
