7.7.3.2 X2 PROFINET
Requirement
The I/O module has certified PROFINET interfaces, however their functionality cannot be fully
utilized within the scope of the SINUMERIK 828D control system. Networking within
SINUMERIK 828D is performed via a PLC I/O interface, which is based on PROFINET.
Data Transmission Rate and Cables
The interfaces are designed for full-duplex mode; in other words, the ports can both transmit
and receive. When connecting I/O modules to the SINUMERIK 828D, please use the
preassembled SINAMICS DRIVE-CLiQ signal cables; from a technical point of view, these are
also suitable for use with PROFINET:
● Article number: 6FX2002-1DC00-...
● The transmission characteristics of these cables meet the requirements of CAT5.
● Data transmission speed: 100 Mbps (fast Ethernet).
● The maximum length of the connections between the end device and network component
or between two network components (e.g. switch ports) must not exceed 70 m.
