Application of Fingerprints to Increase Security
This 9-page paper summarizes the various applications and benefits of the use of fingerprints to restrict access to information and transactions. It covers access via the Internet and other networks as well as physical access.
Control System Security: Interacting with IT
Operations staff and plant engineers also have a keen interest in the security of control networks. They are responsible for the reliability, availability, safety and integrity of the process. Their facilities are the ones producing products and earning revenues, so their concerns, priorities and knowledge must also be considered when determining security options.
Achieve 21 CFR Part 11 Compliance
This technical white paper discusses Yokogawas CENTUM CS 3000 R3 DCS (Distributed Control System) product and the extent of its compliance with Part 11 of Title 21 of the Code of Federal Regulations (21 CFR Part 11), the Electronic Records/Electronic Signatures Rule.
Understand Heat-Transfer-Fluid Maximum Temperature Rating
Manufacturers of heat transfer fluids assign a maximum temperature rating to each fluid. This rating must be considered to ensure the safe and efficient operation of the fluid. This paper explains the basis of the rating, how fluids degrade, and how the temperature profile in a heat transfer system affects fluid performance and life.
Succeed at Alarm Management
Today's control system make it easy to add alarms. The result has been a proliferation of alarms that can overwhelm an operator and actually obscure situations that really require immediate attention. This paper provides practical guidance on effective procedures that can significantly reduce nuisance alarms and improve operator effectiveness.

Properly Clean Organic Heat Transfer Fluid Systems
Maintaining peak performance of organic heat transfer fluids can require removal of dirt and pipe scale, oxidation, thermal degradation, and process contamination. This paper describes the appropriate cleaning techniques for dealing with solids; sludge, high-viscosity fluid and residues; process contamination; and hard coke.
Selecting Transmitters for Safety Instrumented Systems
This paper presents best practices that allow the user to quantify the impact of real-world failure causes and to take credit for improvements in system design. Besides selection, it also covers installation and maintenance.
