12 Chapter 1 About the Sequencer Object • Settings - other settings that control the behavior of the Sequencer Object. Step Program The Sequencer Object hosts a Step Program that has a finite number of steps. You can configure the Step Program in the following panel: Steps Steps are processed sequentially unless certain conditions are met that instruct the processing to continue at a specified step (Jump To). The step that is being processed at any given time, is called the Current Step. There is only one current or active step at any given time. The conditions for processing the next step or any specified step are controlled by events (triggers, timers, or a combination of triggers and timers). Sequencer Object User’s Guide
Sequencer Object Structure 13 The following diagram shows this: Step 1 Step 2 Current Step Jump Step 3 ... Step n Outputs You can write values to ArchestrA attributes whenever a certain step becomes active or before Sequencer jumps to the next or another step. Note To write to an ArchestrA attribute you must first map it to an Alias. For specifics, see Aliases on page 14. Every step of the Step Program allows you to associate the step entry and/or the step exit with values that are written to the Aliases. These values form an output matrix. An output value can be one of two types: • literal value (number, string, date time, elapsed time or boolean) • value of another Alias (referencing another ArchestrA attribute) Empty cells in the matrix mean that no write to the the associated Alias takes place. Literal Values You can configure a step to write literal values to attributes either when a step becomes active or after the step is triggered, either by the step condition or the jump condition. Some examples of literal values are 3.141, 17, “Start”, and “Pause”. Sequencer Object User’s Guide
