10 PROFINET INTERFACE
NOTE
For BIS M-628-075-A01-03-ST34 models.
10.1 PROFINET OVERVIEW
Profinet is the open industrial Ethernet standard of PROFIBUS & PROFINET International
(PI) for automation. Profinet uses TCP/IP and IT standards, and is, in effect, real-time
Ethernet. The Profinet concept features a modular structure so that users can select the
cascading functions themselves. They differ essentially because of the type of data
exchange to fulfill the partly very high requirements of speed. Profinet is defined by
PROFIBUS & PROFINET International (PI) and backed by the INTERBUS Club and, since
2003, is part of the IEC 61158 and IEC 61784 standards.
10.2 PROFINET IO
In conjunction with PROFINET, the two perspectives PROFINET CBA and PROFINET IO
exist.
PROFINET CBA
Suitable for
component-based communication via TCP/IP and real-time
communication for real-time requirements in modular systems engineering.
PROFINET IO
Developed for real time (RT) and isochronous real time (IRT) communication with
decentral periphery. The designations RT and IRT merely describe the real-time
properties for the communication within PROFINET IO.
The Profinet Controller supports Profinet IO :
MAIN FEATURES:

Complies to conformance class B

Device characteristics stored in a .GSD file, used by PROFINET engineering tools
when setting up the network configuration.

100Mbps, full duplex with auto-negotiation enabled as default

Up to 248 bytes of IO Data
