Networking
The SINUMERIK 840D sl offers integrated PROFINET functionality. Supported:
• PROFINET CBA
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.
• PROFINET IO
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.
128 PROFINET IO devices can be operated on the NCU as an IO controller.
2.3 Variants
The scalability of the hardware and software – both from a CNC perspective and in terms of
operation – means the SINUMERIK 840D sl can be used in many sectors. The possibilities range
from simple positioning tasks up to complex multi-axis systems.
