MCI Board
Together with the PCU, the MCI Board constitutes the hardware basis for the
SINUMERIK 840Di. The most important components installed on the MCI Board
are:
•
PLC: SIMATIC S7 CPU 315-2DP
•
SRAM for retentive NC and PLC data
•
an MPI interface (Multi-Point Interface) (1.5 MBaud)
•
a PROFIBUS-DP interface (12 MBaud, electrical)
•
an MCI-Board Extension interface
PROFIBUS DP
The PROFIBUS-DP interface of the MCI Board is used to connect the SINUMERIK
840Di to the drives and the I/Os.
•
Drive systems
Either the modular converter system SIMODRIVE 611 or the distributed drive
system POSMO A, SI, CD/CA can be used as the drive system. Drives with an
analog setpoint interface can also be connected to PROFIBUS DP via the
interface module ADI4 (Analog Drive Interface for 4 Axes) (available soon).
•
I/Os
Either the range of the SIMATIC DP ET 200 modules (for the connected loads,
see SIMATIC Documentation) or the I/O module PP 72/48 (3x24 dig. inputs,
3x16 dig. outputs) can be used as I/Os.
MPI
The MPI interface of the MCI Board serves for optional connection of additional
operator components, such as of a machine control panel, a handheld unit
(handheld operator or programming unit) or of an external programming device
(PG) for programming or diagnosing the PLC.
MCI Board Extension
An MCI-Board Extension Board is offered as an option. Using this expansion board
for the MCI Board, sensing probes, handwheels and fast digital I/Os can be
connected via a SINUMERIK cable distributor.
Operator components
As operator components, the new operator panel fronts from the SINUMERIK
family (OP 010, OP 010C, OP 010S, OP 012, OP 015) are available optionally.
Further components that can be connected optionally are PS/2 mouse, PS/2
standard or CNC full keyboard. It is also possible to connect a standard PC monitor
via the VGA interface.
