CHAPTER 6 BATCH CONTROL
This chapter gets you using some of the Instrument’s Batch functionality, for which you must have purchased the LO2
Batch option.
You start off by adapting the setpoint program strategy you built in Chapter 3, to make it ‘drive’ the instruments’ batch
engine. That is, you use the setpoint program segments to define the batch phases. You also include a recipe set,
based on the one you configured in Chapter 5, so that you can vary batch parameters.
After that you add batch reporting, and customise some of the batch screens to enhance the application. This involves
editing the batch file and creating a user dictionary and a report form file.
The main sections in this chapter are:
„
Modifying the programmer strategy for batch
„
Creating batch files
„
Running the batch application
„
Enhancing the batch application
„
Running the enhanced batch application
The Batch functionality is used to control the parameters that change based on the product or formula. Each Batch is
the single process that produces the required product.
6.1 MODIFYING THE PROGRAMMER STRATEGY FOR BATCH
Figure 6-1 shows the (simulation) programmer strategy you created in Chapter 3, but with a Batch Control block and
two recipe blocks, Recipe Set and Recipe Line, added to give the strategy some batch and recipe functionality.
RECIPE blocks
[Batch Category]
Control the down-loading
of recipes from a recipe
set file to a plant line.
(Refer to Chapter 5
for details.)
BAT_CTRL block
[Batch Category]
Controls the loading (from a
.UYB batch file) and running of
a batch. It provides a
command interface into the
batch engine, along with status
and support information.
