Hardware Components
Hardware Basis:
The hardware basis of a SINUMERIK 840Di sl is an industrial-PC of SIEMENS A&D,
referred to as PCU (PC-Unit) from now on, together with the MCI-Board (Motion Control-
Interface).
PCU
The SINUMERIK 840Disl is available with the following PCU 50.3 versions, each with 24 V
power supply:
●
PCU 50.3-C: 1.5 GHz, 512 MB SDRAM
●
PCU 50.3-P: 2.0 GHz, 1024 MB SDRAM
PCU interfaces
The PCU 50.3 features interfaces to connect the SINUMERIK operator panel fronts (OP 0xx)
as well as standard PC interfaces for connecting, e.g. monitor, keyboard, mouse, and
Ethernet connection.
PCU slots
The PCU 50.3 has the following slots:
●
1 x PCI (length: max. 175 mm, occupied with option MCI board extension and MCI board
extension slot variant)
●
1 x PCI (length: max. 265 mm, occupied by the MCI board)
MCI2 board
The MCI2-Board, called only as MCI-Board from now on, is a small PCI-slot card with
integrated SIMATIC S7-compatible CPU PLC317-2 DP as the DP-Master with routing
capability. The MCI board has the following external interfaces:
●
PROFIBUS DP with Motion Control Functionality (Master)
●
MPI (Multi-Point Interface)/PROFIBUS DP (Master/Slave)
●
MCI board extension (option)
PROFIBUS DP interface X101
The PROFIBUS DP interface (X101) can be used to connect drives, distributed ext. I/Os,
machine control panels, programming units, etc. via PROFIBUS DP with motion control
capability (clocked and isochronous data exchange between the DP master and DP slaves)
to the SINUMERIK 840Di sl. Both the PLC and the NC have direct access to this PROFIBUS
interface.
