Function
Performance and flexibility
The scalability of the hardware and software – both in the CNC
and the operating area – provides exceptional conditions for
using SINUMERIK 840D sl in many sectors. The possibilities
range from simple positioning tasks up to complex multi-axis
systems. We offer different types of NCU for your machining
tasks.
A total of 8 axes is provided by SINUMERIK 840D sl with
NCU 710.3B PN, while the number of axes can be increased
to a maximum of 31 in combination with the NCU 720.3B PN/
NCU 730.3B PN. A total of 3 × 31 axes is possible with the
CBE30-2 communication module.
Siemens has bundled its entire milling expertise into the
SINUMERIK MDynamics technology packages which allow
users to attain outstanding milling results in terms of perfect
surface quality, precision, quality and speed:
•
Powerful CNC hardware and intelligent CNC functions
•
Simple operation
•
Unique CAD/CAM/CNC process chain
•
Technological expertise in all industries
Use of an NCU 720.3B PN or NCU 730.3B PN is recommended
where excellent dynamic response and accuracy are required
for mold making applications or in the high-speed cutting (HSC)
range.
PROFINET functionality
PROFINET is the leading Industrial Ethernet Standard.
PROFINET is based on tried and tested IT standards and fully
supports TCP/IP – for company-wide data transfer across all
levels. It also offers integrated diagnostics and fail-safe commu-
nication to ensure maximum plant availability, modular machine
concepts for outstanding flexibility, as well as very fast transfer
rates and WLAN applications for significantly enhanced perfor-
mance.
PROFINET IO is a communication concept for the implementa-
tion of modular, distributed applications. PROFINET IO is based
on Industrial Ethernet and allows distributed field devices and
I/O devices to be connected to the NCU.
128 PROFINET IO devices can be operated as IO controllers.
The integrated PROFINET CBA (Component Based Automation)
functionality for machine-to-machine communication allows
users to modularize technologically machines and systems on a
process-specific basis and benefit accordingly: Systems are
easier to standardize and easier to reuse or extend. Response
to customer demands is faster and more flexible and startup is
simplified and speeded up by pretesting at component level.

System-wide openness
Thanks to openness across the HMI, CNC and PLC, users can
apply their specific expertise such that they achieve exactly the
individual control solution desired. SINUMERIK 840D sl offers
openness right down to the NCK level. This open architecture
and the high computing performance of the SINUMERIK
840D sl
mean that the CNC functions can be adapted to many different
innovative machine kinematics flexibly, rapidly and cost-effec-
tively. Additional technology-specific functions can be sub-
sequently loaded as compile cycles.
Integrated safety functions
Integrated safety functions (SINUMERIK Safety Integrated) are
available with SINUMERIK 840D sl. The safety functions comply
with the requirements of Category 3 as well as Performance
Level PL d according to EN ISO 13849-1 and Safety Integrity
Level SIL 2 according to EN 61508. Consequently, highly
effective protection for personnel and machines is achieved in
a simple, economical and practical manner.
