The RPC SINUMERIK-OCX development package is an add-on product for the
RPC SINUMERIK computer link.
The RPC SINUMERIK computer link provides an interface for communication
between a SINUMERIK 840D machine control and a higher-level host computer.
Communication between the host computer and the machine control is performed
in this arrangement via RPCs (Remote Procedure Call). Because the RPCs are a
platform-independent standard, the RPC SINUMERIK interface can be used both
by MS Windows and by UNIX, LINUX and other systems.
