Passivation
If the F-I/O detects a fault/error, it switches the affected channel or all its channels to the safe
state. In other words, channels of this F-I/O are passivated. The F-I/O reports the detected
error to CPU via the slave diagnostics. With an F-I/O with inputs, passivation is performed by
the the F system by making available substitute values (0) to the safety program instead of
the process values queued at the fail-safe inputs. With an F-I/O with outputs, passivation is
performed by the the F system by sending substitute values (0) to the fail-safe outputs
instead of the output values provided by from the safety program.
PROFINET
Within the framework of Totally Integrated Automation (TIA), PROFINET represents an
enhancement of the following bus systems:
● PROFIBUS DP as well-established field bus
● Industrial Ethernet as the communication bus for the cell level
The experience gained from both systems has been and continues to be integrated in
PROFINET. PROFINET as an Ethernet-based automation standard from PROFIBUS
International (PROFIBUS Nutzerorganisation e.V.) defines a vendor-independent
communication and engineering model.
PROFINET IO controller
Device used to address the connected IO devices. That is: 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 PROFINET IO device is a decentralized field device that is assigned to one of the IO
controllers (e.g., remote IO, valve terminals, frequency converters, switches)
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 extended blocks
and system status lists for PROFINET IO.

F-I/O in an F system.
