PC-based phases

A PC-based phase allows you to program a phase outside of a process-connected device (PCD). You can program the phase to meet your own unique requirements from within your Microsoft-compatible control container. The PC-based phase works the same way as any phase defined in a PCD, communicating with the

FactoryTalk Batch

Server through the

Batch Phase Execution

control. This saves your system’s memory for processes requiring interaction with hardware.

After a PC-based phase is created, the

FactoryTalk Batch

area model must be updated to include the new phase and the appropriate equipment modules. Because the

Batch Phase Execution

control behaves as a data server, a new data server definition must be created. The data server definition is created using

FactoryTalk Batch Equipment Editor

, and defined using the

Batch Phase Execution

control’s communication parameters. The phase can then be added to your recipes. The PC-based phase must remain active during recipe execution, allowing the phase to communicate with the

FactoryTalk Batch

Server through the

Batch Phase Execution

control.

An activity log file is created for each PC-based phase when it runs. This log file,

Singleton.log

, is written to the

WINDOWS\system32

directory.
