Topic 5.1.1: Overview of Trains

  • Trains provide a way to represent various paths through the process. A train can contain one or more units.
  • A unit can be included in as many trains as necessary.
  • The Train Editor is used to create lines of production that are assigned to scheduled batches.
  • The batch management system is responsible for scheduling and executing batches. Each batch consists of, (among other things), a recipe and a train assignment.
  • The recipe is typically equipment independent.
  • The train is used to provide a list of potential equipment to the batch engine for dynamic selection while the batch is executing.
  • If a unit is not in the assigned train, then it is not available to be used for the scheduled batch.
  • The train data is maintained in the process model database. The Train Editor writes to both the configuration process model database and the runtime process model database.
  • Trains can be added at anytime during batch system execution.
