Investments in process control systems will claim a large percentage of capital investments in modern manufacturing facilities. In order to maximize return on these investments, automation concepts must be developed at the early stages of the project and detailed in parallel with the process, equipment, and facility components as the engineering work progresses. However, it is difficult to illustrate control strategies for complex batch operations on PFDs and P&IDs, therefore the control system Functional Specification must come to life early and be used more effectively as a living document which is developed together with the process design. This paper presents a case study on the application of S88.01 in the design of a multi-product biotech manufacturing facility, where flexibility, modularity, and CGMP compliance were major objectives. It shows how the models presented in the standard can be applied to develop automation concepts, which are defined in a Functional Specification that supports effective review and input by all members of the project team. This approach ensures that the automation strategy meets the project objectives, and that important concepts are not lost or mistranslated in the transition from concept through detailed design and final implementation.
