Glossary
PROFINET component
A PROFINET component includes the entire data of the hardware configuration, the
parameters of the modules, and the corresponding user program. The PROFINET
component is made up as follows:
● Technological Function
The (optional) technological (software) function includes the interface to other PROFINET
components in the form of interconnectable inputs and outputs.
● Device
The device is the representation of the physical programmable controller or field device
including the I/O, sensors and actuators, mechanical parts, and the device firmware.
PROFINET IO
As part of PROFINET, PROFINET IO is a communication concept that is used to implement
modular, distributed applications.
PROFINET IO allows you to create automation solutions which are familiar to you from
PROFIBUS.
PROFINET IO is implemented by the PROFINET standard for automation devices on the
one hand, and on the other hand by the engineering tool STEP 7.
That is, you have the same application view in STEP 7, regardless of whether you configure
PROFINET or PROFIBUS devices. Programming your user program is essentially the same
for PROFINET IO and PROFIBUS DP if you use the extended blocks and system status lists
for PROFINET IO.
PROFINET IO controller
Device used to address connected I/O devices. This means that the IO controller exchanges
input and output signals with assigned field devices. The IO controller is often the controller
on which the automation program runs.
PROFINET IO device
A distributed field device that is assigned to one of the IO controllers (e.g., remote IO, valve
terminals, frequency converters, switches).
URL
Uniform Resource Locator (URL). Identifies and localizes a source, such as a web page,
uniquely via the method of access used and the location of the source in computer networks.
