Chapter 8 PC-based phases introduction

during recipe execution, allowing the phase to communicate with the
FactoryTalk Batch Server through the Batch Phase Execution control.
An example of a PC-based phase executing within a recipe is shown. The PC-
based phase is created to prompt the operator to take a sample to Quality
control (QC) and then enter the results. The phase communicates with the
FactoryTalk Batch Server by way of the Batch Phase Execution control. The
phase can direct the server to prompt the operator, wait for results and have
the FactoryTalk Batch Server store the result in the electronic batch record.
The recipe will only proceed if the result is within the appropriate range.
In Step 1, as the batch is processed, the QC_Chk phase is executed.
In Step 2, the QC_Chk phase displays a screen to the operator, requesting that
the operator have QC take an in-process sample. The QC_Chk phase will not
continue processing until the operator enters the QC result.
In Step 3, When the operator enters the result, the QC_Chk phase sends the
report value to the FactoryTalk Batch Server, using the Batch Phase Execution
phase example
