A software application that communicates with another software
application (the client). The server normally supplies data or functions
to the client. The FactoryTalk Batch Server is both a client and a server.
When communicating with the FactoryTalk Batch View component,
the FactoryTalk Batch Server acts as the server; when communicating
with a data server, it acts as the client.

include a graphic user interface. Services often include an application
programming interface that can be called by other processes and
remotely from other computer nodes.

control Windows services. The FactoryTalk Batch Service Manager
allows an operator to control all batch-related services, as well as access
the Server Statistics dialog box.
