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. This concept satisfies demands for a higher degree of
modularity in the field of mechanical and systems engineering by extensive distribution of
intelligent processes.
Component based Automation allows you to use complete technological modules as
standardized components in large systems.
PROFINET CBA is implemented by:
• the PROFINET standard for programmable controllers and
• the SIMATIC iMAP engineering tool.
The components are also created in an engineering tool that can differ from vendor to
vendor. Components of SIMATIC devices are generated, for example, with STEP 7.
The following figures illustrate how automation solutions are being transformed as a result of
PROFINET CBA.
