Using Operator Interfaces to Optimize Performance of Industrial Wireless Networks
The performance of wireless networks can change over time due to increased performance demands, changes in the radio frequency (RF) environment and changes in the physical environment. This article will explore the use of a wireless diagnostic OLE for Process Control (OPC) server technology to embed diagnostic information in human machine interfaces (HMIs), thus optimizing industrial wireless network performance.

Intelligent Rotary Control Valve
NELES rotary control valves with Q-Trim have greater capacity than comparable globe-style linear valves with noise reduction trims widening rangeability, reducing weight and valve dimensions, and a 50% cost reduction compared to linear valves of comparable Cv. NELES rotary control valves from Metso Automation. Intelligent Reliability leads to Intelligent Results.
IT Security for Process Control Using Siemens SIMATIC PCS 7
Ensuring the security of industrial control systems is hardly a new topic. The earliest users of modern control systems in power stations and chemical plants saw the need to protect access to vital control functions from unauthorized use. Similarly, in industries such as fine chemical or pharmaceutical
where the process is the product, manufacturers have always sought to protect the secrets of their unique processes from the prying eyes of industrial spies. This white paper by ARC describes how the Siemens AG PCS7 Security Concept bundles key security measures in seveal specific areas to create a deep hierarchy of security known as defense in depth.

Design Considerations for High Liquid Rate Tray Applications
Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications.
Managing Complex Equipment Status in a GMP Environment
Batch manufacturing systems must maintain the status of equipment, including which are available, dirty, out of service, etc. In industries that enforce Good Manufacturing Practices (GMPs), additional status types and values for process equipment must be maintained. Rules associated with the equipment status can be complex and involve the equipment class, current equipment state and time in the current
state. This paper covers the operator interface used to review the equipment status and the interlocking requirements between the recipe and batch phases based on multiple status types.
Securing Batch Control Systems
Batch process control security is becoming a critical concern for the process control domain, IT technology infrastructure and the business enterprise. This paper explores several key security concerns in batch control system architectures and methods for addressing these issues.
White Paper: Internet Access in a Process Control Environment
Industrial automation is no longer limited by the walls of a production facility. More and more automation is being handled via remote communication, whether its from the office or from the comfort of your own home. Todays PLCs give you the ability to access your control system to
handle such tasks as monitoring via a website to determine the condition of a machine or check other statistics.

In the real world, sharing PCN data with external systems and accessing PCN systems from external
sources is fast becoming a business necessity. This paper provides some generic guidelines for enabling
secure connectivity between PCNs and external systems.
PACs for industrial control: The future of control
With a number of vendors producing Programmable Automation Controllers that combine the functionality of a PC and reliability of a PLC, PACs today are increasingly being incorporated into control systems. This white paper explores the origins of the PAC, how PACs differ from PLCs and PCs, and the future direction of industrial control with PACs.
Hazard Communication Guidelines for Compliance
OSHAs Hazard Communication Standard (HCS) is based on a simple conceptthat employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working.
