Regulatory modifications in 2010 have raised important issues in design and use of industrial safety systems. Certain changes in IEC 61508, now being widely implemented, mean that designers and users who desire full compliance must give new consideration to topics such as SIL levels and the transition from 1H to 2H methodologies.
This paper will discuss the methods used to ensure that the integration between the safety system and the BPCS DO NOT compromise Functional Independence and define best practices to secure an industrial system and in particular safety systems in this integrated environment.
Leaking or overfilled tanks containing chemicals, fuel oil, sewage or hazardous materials can cause environmental problems, contaminate drinking water and cost a company millions of dollars in fines and lawsuits. This white paper discusses instrumentation and controls that can monitor the contents of a vessel and provide an alarm in the event of a leak or overfill event.
The EU's cybersecurity Agency ENISA released this white paper, giving recommendations regarding prevention and preparedness for an agile and integrated response to cybersecurity attacks and incidents against industrial control systems (ICS)/SCADA.
Process industries are inherently hazardous, and maintaining safety in processes and operations has become increasingly complex and costly. With both safety and financial concerns being a high priority, those in the process industry sometimes struggle to reconcile them.

When a storage facility's tank level rises above safe limits, a logic solver that is part of a Safety Instrumented System (SIS) initiates final elements to restore the process to a safe state. This can include shutting off input feeds to the tank by isolating the pump and closing the input valve. This white paper explores the possibilities available to SIS designers of tank overfill protection systems when using a logic solver. It includes examples of system topographies and their associated Safety Integrity Level (SIL) calculations.
Wireless technologies have been used for decades in the water/waste water industry in a multitude of applications including tank level indication, pump and motor control, flow and pressure monitoring, etc. However, recent concerns regarding the potential for hacking and cyber-attacks into these wireless systems have raised the importance of wireless security to a new high. This paper will discuss security issues within an Industrial Wireless Network, and address the ways in which these networks can be designed to be more reliable while being more secure.
This whitepaper by Gregory Hale, editor and founder of Industrial Safety and Security Source, explores how OPC UA provides a secure information gateway that is changing the way information is transferred in automation environments.
Process engineering has undergone significant transformation over the years, catalyzed by advances and innovation in software both within individual disciplines and also in the integration across the workflow.
The ability to securely move information between software applications and hardware appliances is critical to any automated process. To make this possible, an interoperable communications platform must be layered into the control system. This "defense-in-depth" approach ensures that critical information will not be deciphered by non-authorized applications for malicious use. This approach also limits the scope of activities that each authorized user is allowed to do and/or access in the system in order to minimize unintentional mistakes that may cause downtime or impact safety. With KEPServerEX V5.12 and the new Security Policies Plug-In, Kepware now provides a complete solution to this market need. Read the full Application Note from Kepware's President and CEO, Tony Paine, to learn more.
FDT Technology is an international standard developed to standardize the communication and configuration interface between smart field devices and their host systems. The enhancements and development from FDT to FDT2 were driven by changing technology and user requirements. The challenges were to maintain all existing features and benefits, add new capabilities based on real-world applications and enhance areas of identified improvements, all this done against a backdrop of maintaining backward compatibility. The following overview of the enhancements included in FDT2 identifies how the specification has addressed the needs of users and suppliers.
