Over the past several decades, intrinsic safety has established itself as the preferred method of explosion protection for global energy and petrochemical projects. This latest installment in Control's "Essentials of" series explains the ins and outs of intrinsic safety technology, how it compares with other methods of explosion protection, and new technology development poised to increase the scope of its application to higher energy systems.05/19/2013
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.05/15/2013

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.12/26/2012

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.11/08/2012
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.11/05/2012
