Implementation of PROFINET by us
We have integrated PROFINET as follows:
• We have implemented communication between field devices with PROFINET IO.
• We have implemented communication between controllers as components in
distributed systems with PROFINET CBA (Component based Automation)
• Installation engineering and network components are available in SIMATIC NET.
• Established IT standards from the Office environment (e.g. SNMP=Simple Network
Management Protocol for network parameter assignment and diagnosis) are used for
remote maintenance and network diagnostics.
Documentation from PROFIBUS International on the Internet
Numerous texts on the subject of PROFINET are available from the URL
"http://www.profinet.com
" from PROFIBUS International (formerly PROFIBUS Nutzer-
Organisation, PNO)
For further information, refer to Internet address " http://www.siemens.com\profinet\".
What is PROFINET IO?
Within the framework of PROFINET, PROFINET IO is a communication concept for the
implementation of modular, distributed applications.
PROFINET IO allows you to create automation solutions, which are familiar to you from
PROFIBUS.
That is, you have the same application view in STEP 7, regardless of whether you configure
PROFINET or PROFIBUS devices.
What is PROFINET CBA (Component Based Automation)?
Within the framework of PROFINET, PROFINET CBA is an automation concept for the
implementation of applications with distributed intelligence.
PROFINET CBA lets you create distributed automation solutions, based on default
components and partial solutions.
Component-based Automation allows you to use complete technological modules as
standardized components in large systems.
The components are also created in an engineering tool which may differ from vendor to
vendor. Components of SIMATIC devices are created, for example, with STEP 7.
