The MCI board extension occupies mechanically one slot in the PCU. The elec-
trical connection, however, is exclusively made using a ribbon cable connected
to both sides.
The MCI board extension slot variation is an electrically compatible successor
version to the MCI board extension module described above. It was extended
by the option of operating differential handwheels or TTL handwheels.
The MCI board extension external variation is a module that is electrically identi-
cal with the MCI board extension internally. To free the PCI slot of the PCU,
which is normally already taken up, for other purposes, in this variation mechan-
ical fixture is implemented in a modified housing cover of the PCU.
For interpolating traversing of axes on the PROFIBUS, the SINUMERIK 840Di
uses the functionality defined in the PROFIDrive profile drive technology (Ver-
sion 1.4.2, 01. Sept. 00) "Motion Control with PROFIBUS DP".
To this aim, Siemens offers the following drives:
– SIMODRIVE 611 universal
with option module MotionControl with PROFIBUS DP
– SIMODRIVE 611 universal E
with option module MotionControl with PROFIBUS DP
– SIMODRIVE POSMO CD/CA
– SIMODRIVE POSMO SI.
In addition to traversing axes with interpolation, it is also possible to have the
drives positioned at PROFIBUS automatically and independently of other drives
(operating mode: Positioning).
To this aim, Siemens offers the following drives:
– SIMODRIVE 611 universal
with option module MotionControl with PROFIBUS DP
– SIMODRIVE 611 universal E
with option module MotionControl with PROFIBUS DP
– SIMODRIVE POSMO CD/CA
– SIMODRIVE POSMO SI
– SIMODRIVE POSMO A.
To operate drives with an analog setpoint interface, the following PROFIBUS
module is available:
– ADI4 (Analog Drives Interface for 4 Axis).
For use as distributed I/Os, the module range SIMATIC DP ET 200 (for the con-
nection conditions, see SIMATIC Documentation) and the low-cost I/O Module
PP 72/48 are available.
Choose one of the new operator panel fronts from the SINUMERIK range (OP
010, OP 010C, OP 010S, OP 012, OP 015) as an operator component.
