SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
1 General Information on the SINUMERIK 840Di sl
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.
The PCU 50.3 has the following slots:
– 1 x PCI (length: max. 175 mm, occupied with option MCI board exten-
sion and MCI board extension slot variant)
– 1 x PCI (length: max. 265 mm, occupied by the MCI board)
The MCI2 board, further referred to as the MCI board is a short PCI plug–in card
with integrated SIMATIC S7 compatible CPU:
S
PLC317–2 DP
as a routing–capable DP Master. 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)
This 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.
Unlike the PROFIBUS DP interface (X101), interface (X102) can only be ac-
cessed via the PLC. As a result, no drives and no NC I/Os can be operated via
this interface.
The interface (X102) can also be operated as an MPI interface.
A maximum of four fast digital I/Os, two sensing probes and two handwheels
each can be connected using the optional MCI board extension slot variant.
Either differential or TTL handwheels can be operated.
The module is inserted into a slot in the PCU and is connected to the MCI board
via a ribbon cable.
SINUMERIK 840Di sl is available with the components from the new SINAMICS
range of drives offering the following characteristics:
– SINAMICS S120
The drive components from the SIMODRIVE range of drives offering the follow-
ing characteristics can also be used:
– SIMODRIVE 611 universal and universal E
with option module MotionControl with PROFIBUS DP
