An Integrated System with Batch functions And Front-End Scheduling based on S88 - Application to Beverage Plant -
The case study in this paper illustrates the value of integrating front-end scheduling with a batch control system. Recipe changes, and addition of recipes, occur frequently in the target process. However, since both scheduler and batch packages were designed with the ISA-S88.01 model in mind, these packages could be tightly coupled (well integrated) and, as a result, it is easy to add or change recipes. The frontend scheduler is not limited to performing scheduling; it also provides an easy-to-grasp real-time production status display which can help enhance efficiency and productivity.08/28/2008
Looking for a solution to deter, prevent, detect and mitigate potential threats? Ensuring safety goes far beyond simply installing fail-safe controllers or a safety instrumented system. In fact, to mitigate the risk of serious incidents that can cause injury to personnel, equipment and the environment, it is important to consider safety from all aspects of a plant's operation.05/14/2008

This paper describes an application of the IEEE 1588 standard to Industrial Automation. Key application use cases are identified that can benefit from time-based control techniques to improve performance results over traditional control methods. This paper will also briefly discuss how the 1588 standard may be adopted to suit these applications. Application problems specific to industrial automation are enumerated and candidate solutions described.01/20/2009
Whitelisting is described by its advocates as "the next great thing" that will displace anti-virus technologies as the host intrusion prevention technology of choice. Anti-virus has a checkered history in operations networks and control systems many people have horror stories of how they installed anti-virus and so impaired their test system that they simply couldn't trust deploying it in production.
While anti-virus systems detect "bad" files that match signatures of known malware, whitelisting technologies identify "good" executables on a host and refuse to execute unauthorized or modified executables, presumably because such executables may contain malware. This is a least privilege approach of denying everything that is not specifically approved.
In this paper the Industrial Defender team performs an independent analysis of a variety of whitelisting solutions for their applicability to control systems. The paper closes with some recommendations related to this technology and areas for further research.02/26/2010
AMS2750D Temperature Uniformity Surveys using TEMPpoint.
Industrial process furnaces and ovens require uniform temperature and heating; This is critical to repeatable product performance from batch to batch. These furnaces require periodic inspection for temperature uniformity.
Electronic and Mechanical Calibration Services, Millbury Massachusetts characterizes temperature uniformity in industrial furnaces and ovens for their customers. This is accomplished by measuring temperature in several locations throughout the furnace and monitoring temperature with thermocouples over time according to AMS2750D specifications.
The customer previously used chart recorders which require constant monitoring while the survey is running. Surveys can run anywhere from 35 minutes to several hours long depending on the industry specified requirements. With the TEMPpoint solution the operator can set it up and let it run unattended, freeing them up to multitask their time and work more efficiently. The shipping TEMPpoint application required very little modification using Measure Foundry and now fulfills customer's requirements.01/06/2010

This special to the web White Paper explains how alarms historically have been viewed as an entity in and of themselves with little thought given to human factors, and how they might help an operator investigate the root cause of why irrelevant alarms obscure more critical alarms.04/12/2005
This White Paper features extensive information on various types of alarm trips, their effective applications and safety factors, and addresses other considerations that need to be made when implementing an alarm trip strategy.06/24/2006
Something happensa signal peaks or fallsand you need to know. A limit alarm trip triggers the response you need to maintain normal and safe operations. This white paper will show you how to back up your DCS and PLC "soft" alarms with the reliability of "hard" alarms.01/12/2010
By reducing the number of alarms and enabling the audible alarming function of its control system, GFS Computing was able to restore audible alarming on half of its operator consoles, leading to tangible, measurable improvements in productivity, safety, and cost-reduction.10/18/2005
Alarm rationalization can be a challenge to define and implement, but the LogMate Alarm Knowledge Base (KB) includes built-in features that make it much easier than traditional methods. The Alarm KB comes with standard functionality that aligns with widely accepted best practices. It enables rationalization teams to capture and track all important alarm data. It is a central database of alarm configurations, alarm priority and limit calculations, change management and audit features. It functions as a complete knowledge management tool providing automated alarm data collection, organization and retrieval.11/09/2010
A complete alarm philosophy document (APD) covers all the elements, including design principles, KPIs and escalation policies. Creating an APD to outline these elements is the first step in a successful alarm management project. This paper provides an overview for the essential elements for a complete APD.06/09/2010
