SinuCom NC is a Windows-based tool for starting up the SINUMERIK 840Di NC
using the possibilities for the:
– interactive parameterization of the NC
– option management and license management
– management of series machine start-up files.
The Windows-based user interface 840Di start-up (see Section 1.5, page 1-38)
has the basic operation functionality to allow the operator to become familiar
with the SINUMERIK 840Di.
840Di start-up is part of the scope of supply of a SINUMERIK 840Di and is al-
ready installed on the hard disk of the PCU.
The following components of the SINUMERIK HMI modular system can be used
optionally:
S
SINUMERIK HMI Advanced (option)
HMI Advanced is the SINUMERIK standard user interface intended espe-
cially for machine tools.
S
SIMATIC Protool/Pro and Protool/Pro Option SINUMERIK
SIMATIC Protool/Pro and Protool/Pro Option SINUMERIK are configuring
packages for creating technology-specific user interfaces.
An operator interface configured in this way can only be run if the ProTool/
ProRuntime System is installed.
S
SINUMERIK HMI Programming Package
The HMI Programming Package can be used to integrate OEM high-level
language applications using standardized interfaces (COM/OPC). The OEM
provides maximum flexibility for creating operator interfaces using standard
development tools (such as Visual C++).
The HMI Programming Package comprises mainly the description of the
interfaces and appropriate sample applications. Detailed information on the
OPC interface can be called from the Internet at the address of OPC
Foundation (http://www.opcfoundation.org.) .
As already mentioned, Windows NT is not an operating system designed for
hard real-time requirements. Hard real-time requirements mean the operating
system will respond to an external event within a defined time frame of a few
µseconds.
The NC system software is therefore integrated in Windows NT as a so-called
Kernel mode driver and thus has its own integrated real-time system that paral-
lel to Windows NT provides for the appropriate real-time prerequisites.
