11 Chapter 1 About the Sequencer Object This section helps you understand the basic features of the Sequencer object, what they do, and how they interact. What is the Sequencer Object? The Sequencer Object is an ArchestrA application object. It lets you configure, execute, and manipulate a sequence of operations associated with ArchestrA attributes within an Industrial Application Server application. You can use it to automate: • repetitive manufacturing procedures with a finite number of steps • supervisory processes with a finite number of steps Sequencer Object Structure A Sequencer Object consists of three main parts: • Step Program - a collection of steps that define the reading and writing operations associated with ArchestrA attributes via Aliases. When in operation, the Sequencer object advances cyclically through the steps or jumps based on various events, conditions, and timers. Inputs are evaluated and values are written to defined outputs. • Aliases - a list of names that are mapped to ArchestrA attributes. The Sequencer Object uses these names internally to associate inputs and outputs with ArchestrA attributes. Sequencer Object User’s Guide
