PROFINET component
A PROFINET component includes all data of the hardware configuration, the parameters of
the modules, and the associated user program. The PROFINET component comprises the
following elements:
•
Technological function
The (optional) technological (software) function includes the interface to other PROFINET
components as interconnectable inputs and outputs.
•
Device
The device represents the physical automation device or field device, including the IO,
sensors and actuators, mechanical system, and device firmware.
PROFINET device
A PROFINET device always has at least one Industrial Ethernet connection. In addition, a
PROFINET device can also have a PROFIBUS connection and even act as a master with
proxy functionality. In exceptional cases, a PROFINET device can also have several
PROFIBUS connections (e. g. CP 5614).
PROFINET IO
Within the context of PROFINET, PROFINET IO is a communication concept for
implementing modular, distributed applications.
With PROFINET IO, you can create automation solutions using the trusted and familiar
methods of PROFIBUS.
PROFINET IO is implemented with the PROFINET standard for automation devices on the
one hand and the STEP 7 engineering tool on the other hand.
This means that you have the same application layer in STEP 7 - regardless of whether you
configure PROFINET devices or PROFIBUS devices. The programming of your user
program is identical for PROFINET IO and PROFIBUS DP when you use the blocks and
system status lists expanded for PROFINET IO.
PROFINET IO controller
Device by means of which connected IO devices are addressed. This means: that the IO
controller exchanges input and output signals with assigned field devices. The IO controller
is often the controller in which the automation program is executed.
PROFINET IO device
Distributed field device assigned to one of the IO controllers
(e.g. remote IO, valve terminals, frequency converters, or switches).
Programmable controller
An automation system is a programmable logic controller consisting of at least one CPU,
various input and output modules, and operator control and monitoring devices.
