CONFIGURING THE SEQUENCE BLOCK
11.1 GENERAL
Configuring a batch application is easier than ever with the Visual Application Designer
(Vi
Zapp ) Software. Comprehensive Vi Zapp user information is available in the Vi Zapp help
files (vizapp.hlp) and the
ViZapp Tutorial (IB-VIZAPP-TUT). A simple batch process
application has been chosen as an example because of the virtually limitless numbers of
different configurations possible. The application example includes a description of the
required sequence, and a series of detailed step-by-step procedures covering each phase of
the configuration process.
11.2 APPLICATION EXAMPLE
This process application example requires that batches of product be cooked for a specified
time at a controlled temperature. The piping and instrument diagram for this process is shown
in Figure 11-1. The kettle is periodically filled with raw product, brought to the required cook
temperature, held for the specified time, then drained of the finished product.
