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 of
the type with which you are familiar from PROFIBUS. PROFINET IO is implemented by the
PROFINET standard for automation devices on the one hand, and on the other hand by the
STEP 7 engineering tool.
This means that you have the same application view in STEP 7 regardless of whether you
configure PROFINET devices or PROFIBUS devices. Programming your user program is
essentially the same for PROFINET IO and PROFIBUS DP if you use the expanded blocks
and system status lists for PROFINET IO.
Project
A project is the result of a configuration using configuration software. The project normally
contains several screens with embedded system-specific objects, basic settings and alarms.
The project file of a project that was created in WinCC is saved with the file name extension
"*.HMI".
You need to distinguish between a project on the configuration PC and an executable project
on an HMI device. A project may be available in more languages on the configuration PC
than can be managed on the HMI device. The project on the configuration PC can also be
set up for different HMI devices. Only the runtime project that has been generated for the
respective HMI device can be transferred to it.
Project file
A project file is a file from which the executable project file for use on the HMI device is
generated. The project file is usually not transferred and remains on the configuration PC.
The file extension of a project file is "*.hmi".
Proof-test interval
Recurring test for detecting hidden dangerous failures in a safety-related system so that a
repair, if needed, can restore the system to an "as new" condition or as close to this
condition as is practically possible.
Real-time Ethernet
Ethernet for isochronous cycle times of < 1 ms, for example, to meet the high real-time
requirements of drive technology.
Runtime software
The runtime software is a process visualization software used to test a project on a
configuration PC.
