Successful Process Communications Best Kept Secret
Sure, the process engineer is proud of his HMI (human machine interface) and the operations manager is pleased with his KPI (key performance indicators) dashboard and how effectively the system is running with the implementation of his new MES/MIS solution. The historian and analytic solution get all the credit when a field equipment crisis is averted. Does anyone ever think to thank the lowly driver? Without data, the HMI is just a pretty picture, and the best analytics in the world are only ideas without any basis in fact. Plus, tens or hundreds of thousand dollars are spent on that, while the driver budget isn't even a line item on the spec sheet. The communication arteries and veins reach out to all areas of the field equipment, sending and receiving data, efficiently and tirelessly ensuring the ability to acquire, analyze and adapt to the situations at hand.

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.

Applying ISA-S88 to Software Migration Engineering
Dow Chemical maintains thousands of batch control systems world-wide built on its proprietary MOD 5 computer system. Over decades, they have been meticulous to preserve and enhance these systems. Dow intends to preserve and reap the rewards of this diligence by developing reverse engineering best practices and tools to migrate this intellectual property to next-generation platforms.
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.
Fieldbus and remote I/O system comparison

Electro-hydraulic system design: Making the right system choices
Designers who understand and can take advantage of the differences between fluid power and traditional electromechanical power can build machines that produce higher quality output with lower lifecycle costs. This white paper suggests that care must be taken, however, in selecting and sizing the hydraulic system elements and in tuning the motion controller for optimal performance.
