7. PROFINET with COM/DCOM
PROFINET's initial focus was on providing a solution for distributed automation (between programmable industrial controllers or between controllers and intelligent programmable field devices). PLCs or programmable I/O stations are assimilated to components, hence the name of the concept: Component Based Automation (CBA). The term PROFINET CBA is therefore used.
7.1 Component concept for machine modularization
In the field of machine building, we already have a wealth of experience in modularization. Frequently required modules are prefabricated, and can be quickly assembled to form an automated machine or plant when an order is placed.
PROFINET CBA extends modularization to the plant automation solution. Technology modules in the sense...
