Configure Automatic Process Phases
- Last UpdatedOct 29, 2024

Automatic process phases are processed in the control system. Operator interaction can be a normal part of the process or can occur only when abnormal situations arise. Operator actions could involve putting the phase in hold or entering parameter values while the phase is running. Enabling the operator to change parameter values is defined when the formula parameters are configured.
Automatic process phases must have control system phase logic, and therefore, must have phase control and status control bits defined. Interlocks, control buttons, and formula parameters are optional.
When the AVEVA Batch Management System encounters an automatic process phase with an input type parameter, the AVEVA Batch Management System updates the material usage record in the Materials database based on the actual amount used.
For more information on material location assignments, see Using the Material Location Assignment Editor. You can configure the batch control system to handle many different automatic process phases. The following example describes several automatic phases. The phase names correspond to the processing capabilities described in Example: Process Phases and Tags.
-
Phase Name: Heat
Increase the temperature of the unit to a specified temperature at a specified rate. -
Phase Name: Cool
Decrease the temperature of the unit to a specified temperature at a specified rate. -
Phase Name: Soak
Maintain the temperature of the unit at a specified temperature for a specified time. -
Phase Name: Agitate
Turn the agitator on for a specified time. -
Phase Name: AgitOn
Turn the agitator on. -
Phase Name: AgitOff
Turn the agitator off. -
Phase Name: Charge
Coordinated with a source unit discharge phase, this phase represents one of the ways in which materials can be moved and tracked. It is responsible for enabling the flow of a material into the unit. -
Phase Name: Discharge
Coordinated with a destination unit charge phase, this phase represents one of the ways in which raw materials can be moved and tracked. It is responsible for enabling the flow of a material out of the unit.
Possible phase parameter configurations for these automatic process phase examples are shown in the following table.
