Data from FactoryTalk Batch Server
IMPORTANT:
The information in this section only applies to programming phase logic for
PhaseManager
phases assigned to a Logix5000
CIP data server.PhaseManager
phases created with a Logix5000
CIP data server, use the PXRQ instruction provided in Logix Designer
as a means for the phase logic to request data or services from the FactoryTalk Batch
Server. Much of the work involved with writing phase logic centers around defining a sequence of steps for a phase. Some of these steps require interaction with the FactoryTalk Batch
Server. For example, the phase logic for a charge phase may perform these steps to add material to a unit:STEP | Interacts with |
