Equipment Module Overview

An equipment module (EM) is a functional stand-alone grouping of all necessary processing and control equipment required to perform a finite number of specific minor processing activities.  The equipment grouping is made up of control modules (CM), subordinate equipment modules, instruments and vessels.

The primary purpose of the EM is to coordinate the functions of the processing and control equipment it contains.  The EM does not interact directly with I/O.  The EM itself is commanded by an operator, a unit procedure, a unit phase, a batch phase or another equipment module.  The EM is the container for performing the different elements of procedural logic required to achieve the process task (i.e. Major Processing task of a Unit).
