  • Ziegler-Nichols Tuning Rules And Limitations

    The standard reference for PID tuning seems to be the Ziegler-Nichols tuning rules developed in 1942 on a pneumatic controller. Here is how to tune a controller using these rules.

  • RFID in Manufacturing

    In the wake of a Wal-Mart mandate requiring top suppliers to put Radio Frequency Indentification (RFID) tags on cases and pallets of consumer goods by January 2005, Rockwell Automation offers this white paper to help educate manufacturers on how to maximize their investment in RFID technology throughout their enterprise and supply chains. The paper provides a practical guide to extracting measurable value from RFID implementations in plant and warehousing operations.

  • Layered Security in Plant Control Environments

    Process control vendors are migrating plant control technologies to more open network and operating environments. This White Paper explains how layered security can be accomplished by adopting a "best practices" model, developing and implementing an access control plan, and compartmentalizing the network.

  • 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 Yokogawa’s 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.
