Batch Management

Batch Management
This section describes the Batch Management functions.
Flexible Batch Processing
Flexible batch processing permits control logic and resources such as equipment to
be used in a variety of ways to produce different products.
Flexibility is built into the Batch Management approach to configuring recipes. The
master recipe is created by drawing a flowchart of the process using an object
oriented approach. This flowchart is called a procedure function chart (PFC).
The objects used in the PFC represent:
Batch manager actions such as allocating an equipment resource, sending the
operator a message, or collecting data to be used later in a batch report.
Phase operations (created during controller configuration) specifically for the
requirements of a customer.
A subprocedure.
These objects can be combined in any sequence supported by the batch resources.
The system permits configuration of procedures consisting of a single thread of
processing, branched logic, or parallel operations. At run time, the operator
monitors the progress of the batch run while viewing a copy of the diagram created
during procedure configuration.
Flexibility of formulas used to create batch products is enabled in a number of ways:
The equipment phase logic can find parameters specified by name.
Values can be assigned to parameters in a number of ways, including by the
operator at run time (if the recipe is so configured).
The values assigned to parameters can be logical expressions, as well as fixed
values.
Configuration Overview
The tasks required to take advantage of the benefits of the Batch Management
flexible batch subsystem are:
