When abnormal situation arise, keep automation and operations at their combined best through the use of High Performance HMI (HP-HMI) screens. NovaTech graphical designers use HP-HMI principles to reduce visual clutter through minimal use of color for background images. More saturated colors and unique shapes are used to draw an operator’s attention to abnormal situations. Digital value information is replace by more intuitive analog representations and embedded trends provide information rich context at a glance. NovaTech applications engineers work with operators and plant managers to create new and adapt existing graphics to the HP-HMI approach. Early collaboration and feedback during the development process is essential to facilitate operator adoption. D/3′s TotalVision HP-HMI smart graphic objects make it easier to do the right thing at the right time.
High Performance HMI Principles
Human Centric Design considers all aspects of an operator’s interaction with the process control system and plant equipment. Careful consideration is given to the type and amount of information delivered to the operator. The system should be designed to handle and control abnormal situations gracefully and operators of all skill levels should be able to manage many unit operations with ease and handle abnormal situations efficiently, effectively and safely.
Focus on Abnormal Situation Management facilitates safe process and plant operation when anomalies occur. During abnormal situations, the system must attempt to manage and control the process safely. The system must also provide the operator with the necessary information to make good decisions regardless of skill level. The system must not overwhelm operators with too much information.
Layered Graphical Hierarchy provides information required to manage all equipment within an area of responsibility. High level overview graphics allow the operator to quickly determine the condition of all unit operations under her oversight. Mid-level graphics facilitate process adjustments, data entry and more granular unit operation performance, while low level graphics and displays provide for diagnostics and analytics.
Careful Color Selection reduces eye strain, visual clutter, and overall distraction. Good color schemes downplay normal operation and highlight abnormal situations. Alarms are indicated using multiple indicators such as color and shape. Critical alarm colors and shapes must be consistent across all enterprise displays.
Analog vs. Digital While traditional PID graphics sprinkled with color coded digital information provide a reasonable snapshot of what a process looks like at any given moment, analog indicators and graphical trend components provide a richer understanding of where the process is now, where it has been, where it is heading, and whether it is within acceptable limits.
The D/3® Distributed Control System (DCS) is a leading edge process control system that includes a comprehensive suite of software applications, networks, and computing hardware. D/3 features system-wide redundancy and the ability to upgrade without stopping plant operations.
It is fair to say that without a fully functional distributed control system (DCS), a modern plant cannot operate safely and efficiently and in some cases, cannot operate at all. Therefore, it is vital to ensure the integrity of all DCSs and protect them from malicious attacks, accidental corruption, and data breaches that may jeopardize safety or production or may compromise the end user’s competitive advantage in the marketplace.
This paper describes the philosophy and guidelines for keeping your D/3® DCS secure from cyberattacks.
NovaTech, LLC, recently donated its D/3 Process Control System to the University of South Carolina Aiken. The system will provide students of the Industrial Process Engineering (IPE) Program the opportunity to experience a more hands-on approach to designing, building, and managing control systems.
NovaTech announces that it has installed a fully integrated automation system at one of the largest grain loadout facilities on the U.S. West Coast. The facility is a rail receiving to ship loading system that processes corn, soybeans, and wheat.
NovaTech Product Marketing Director, Chris Kourliouros, presented a paper entitled “New Paradigms in Mitigating Unplanned Events Caused by Human Error” on October 25th at the 2017 Texas A&M Mary Kay O’Connor Process Safety International Symposium.
The editors of “Control” magazine were on site at the 2017 NovaTech Automation Summit in Baltimore. They offer coverage of some of the Summit’s presentations addressing process control’s most interesting challenges and pressing problems.
Manufacturing operations culture, alarming methodologies, process safety management practices, standard operating procedures, and automated control strategies must work in harmony to prevent abnormal performance.
As the issue becomes more and more dependent on human and machine integration, new technologies and implementation techniques like advanced procedural automation can be applied, which will greatly affect operational performance.
FlexBatch integrates recipe management and the automation layer so operators can quickly and easily develop, scale up, modify and schedule batch manufacturing recipes for products ranging from beer to chocolate to specialty chemicals and more. FlexBatch delivers shorter time to first batch, reduced changeover times, increased throughput and production yield. New and existing products are brought to market faster and at lower cost, providing a strategic and financial advantage. Production staff can execute library procedures to overcome process upsets. All of which means a more nimble, responsive, and profitable process.
The latest release of the D/3 Distributed Control System includes new configuration tools that make the system easier for new and existing users. The webinar covers building tags with MDL Builder, writing automation code with D3Edit, web-accessible History and Reports, features to facilitate migration to High-Performance HMI, and OSIsoft PI integration.
This video introduces the D/3, the Distributed Control System trusted by many Fortune 100 companies to keep their global operations’ continuous and batch processes running smoothly and efficiently. Part one reviews the system architecture and configuration tools.
