Variants - Siemens SINUMERIK 840D sl Manual

With the NCU 720.2 PN and NCU 730.2 PN, the SINUMERIK 840D sl is offering integrated
PROFINET functionality for the first time.
Supported:
● PROFINET CBA functionality
● PROFINET IO

Variants

The scalability of the hardware and software – both in the controller and operating area –
provides the prerequisites for use of the SINUMERIK 840D sl in many sectors. The
possibilities range from simple positioning tasks up to complex multi-axis systems.
Application areas and performance
● As many as 6 axes can be implemented on an NCU 710. The NCU 710 can be expanded
● On the NCU 720/730, the number of axes and/or the performance of the drive controller
● Use of an NCU 730 is recommended for maximum dynamics and accuracy in mold
● The NCU 730.2 PN is the new flagship of the SINUMERIK 840D sl and, with a

The CBA functionality integrated in the NCU allows users to modularize machinery and
systems: Rapid real-time communication (up to 10 ms) between the controllers means
that systems lend themselves better to standardization and can be reused or expanded
more easily. Response to customer demands is faster and more flexible and startup is
simplified and speeded up by pretesting at component level.
As part of PROFINET, PROFINET IO is a communication concept that is used to
implement modular, distributed applications. PROFINET IO is based on Industrial
Ethernet and allows distributed field and I/O equipment to be connected to the central
processing unit.
256 PROFINET IO devices can be operated on the NCU as an IO controller.
The typical topology with Industrial Ethernet, illustrated above, can be integrated in
exactly the same way using PROFINET IO (or PROFINET components). Using
PROFINET machine control panels or operator panels means, of course, that diagnostics
is available as a PN device.

can be increased to 31 axes. This is achieved by using the NX10/15 module. The NCU
720/730 can be expanded by up to 6 NX10/15 modules in performance for the drive
controller and number of axes.

significantly higher PLC capacity than an NCU 730.2, represents the most advanced
configuration within the SINUMERIK 840D sl range.
