Hardware basis
The hardware basis of the SINUMERIK 840Di is a SIEMENS industrial PC in
conjunction with a PCI plug-in board, the so-called MCI Board (Motion C
ontrol
Interface), which has been developed by Siemens. Depending on the variant of the
industrial PC used, a different number of OEM or end user PC boards (PCI or ISA)
can be plugged optionally.
Drive units and I/Os can be connected to the SINUMERIK 840DI via PROFIBUS
DP with Motion Control functionality (both clocked and in equidistant mode) both
centrally and decentralized.
Software basis
The software basis is the WINDOWS NT standard operating system. In addition, a
software method developed by Siemens allows the operation of the NC software in
real time mode parallel to WINDOWS NT. NC and PLC software, as well as
installation/start-up and operation are already integrated in the system software.
In addition, the open concept allows specific extensions by the OEM or end user
PC software (see also Section "Certification").
