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
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.
