Hardware basic variant
The basic variant of the SINUMERIK 840Di is a compact SIEMENS industrial PC
and a PCI plug-in board, the so-called MCI Board (Motion C
ontrol Interface), which
has been developed by Siemens.
PCU (industrial PC)
In view of different cases of applications, PC variants with a differentiated scope of
performance and expandability are planned. The first product stage envisages the
PCU 50 (PC U
nit), a built-in industrial PC with a free ISA/PCI slot for hardware
expansions in two variants (Pentium II/III at 333MHz/500MHZ) for the SINUMERIK
840Di.
A PCU variant with additional free PCI slots is available soon.
