Using SIMATIC MicroComputing with
DCOM
D
Chapter Overview
SIMATIC MicroComputing allows you to communicate across networks using the
Microsoft Distributed Component Object Model (DCOM). You can use DCOM to
integrate distributed applications by way of a network. A distributed application
consists of multiple processes or different computers that cooperate to accomplish
a single task.
DCOM is a set of Microsoft concepts and program interfaces in which client
program objects can request services from server program objects on other
computers in a network. The Component Object Model (COM) provides a set of
interfaces that allow clients and servers to communicate within the same computer
(running Windows 95/98 or Windows NT).
Note
The control engine must be installed on the server computer. If you plan to use the
SIMATIC controls provided with MicroComputing to access the control engine,
install the MicroComputing software on both the server computer and the client
computer.
