Data servers overview
A
FactoryTalk Batch
data server is a system object that is a reference to
an OPC, FactoryTalk Linx
FactoryTalk Live Data
, or Common Industrial Protocol (CIP) data server
program and one of its associated data sources. These data server references provide
run-time information from the process-connected device (PCD) to FactoryTalk Batch View
or the HMI software. Data servers are used to pass
data between the FactoryTalk Batch
Server and the PCD. Configure a
separate FactoryTalk Batch
data server for each data source, and its associated
data server program, that communicates with the FactoryTalk Batch
Server. In
FactoryTalk Batch Equipment Editor
, add a data server definition for each data server program (and its associated data source) that communicates with the FactoryTalk Batch
Server. This allows FactoryTalk Batch
to access current tag data within the PCD, which is necessary to successfully run recipes, arbitrate equipment, and control single phases or operation sequences.
TIP:
The
FactoryTalk Linx
FactoryTalk Live Data
protocol is based on the OPC Data Access protocol. The FactoryTalk Batch
Simulator imitates the functionality of a data server and can communicate with the FactoryTalk Batch
Server using OLE for Process Control (OPC) communications. Sample programs are included with the FactoryTalk Batch
Phase Simulator and can be run to simulate batch processes without being connected to a PCD.Provide Feedback
