Simplify with S88 software
This online article, “Providing flexibility in batch control” by Jeff Elliott, covers some history of the ANSI/ISA88 standard and subsequent software packages designed to carry out S88-style recipes, phases and other functions in similar ways, and achieve comparable advantages. The article shows how Valmet performs state-based control and S88 control using Phase logic and its FlexBatch software.

Predictible + repetible
This Control Talk column, “How to get the best batch control” by Michael Taube and Greg McMillan, shows how to achieve robust batch control applications. This includes computing batch profiles, and using batch control sequences. Taube reports that robust sequences are tolerant of perturbations, can generate predictable and repeatable behavior, require no manual intervention, and don’t overlook initialization.

Steps and methods
The online article, “Batch process control” by Shreya Gore, outlines all the essential steps for effective control, such as define and adjust parameters, set procedures, monitor variables, establish strategies, acquires and analyze data, maintain calibration, document and learn, training and regulatory compliance. It also covers batch control methods using programmable logic controllers (PLC), distributed control systems (DCS), proportional-integrate-derivative (PID), statistical process control (SPC) and supervisory control and acquisition (SCADA).

Phases and modules
This 16-minute video, “What is batch processing?” by Saumil Patel, explains how batch processing differs from traditional programming, and shows how users can implement the principles of the ISA88 standard. It also covers phases concepts, equipment modules and control modules.
