PROFINET IO
Communication concept for the realization of modular, distributed applications within the
scope of PROFINET.
PROFINET IO device
Distributed field device that can be assigned to one or more IO controllers (e.g. distributed
I/O system, valve terminals, frequency converters, switches).
PROFIsafe
Safety-
oriented PROFINET I/O bus profile for communication between the → safety program
and the → F
-I/O module i
n a → fail
-safe system.
PROFIsafe address
The PROFIsafe address (code name according to IEC 61784-3-3: 2010) is used to protect
standard addressing mechanisms such as IP addresses. The PROFIsafe address consists
of the F-source address and F-destination a
ddress. Every → fail
-safe module therefore has
two address portions, the F-source address and the F-destination address.
The PROFIsafe address must be configured in the hardware and network editor.
PROFIsafe monitoring time
Monitoring time for safety-related communication between the F-CPU and F-I/O
Proof-test interval
Period after which a component must be forced to fail-safe state, that is, it is either replaced
with an unused component, or is proven faultless.
Provider-Consumer principle
Principle of data communication on the PROFINET IO: in contrast to PROFIBUS, both
parties are independent providers when sending data.
P-switch
→ M
-switch
Push-in terminal
Push-in connections are a form of spring-loaded terminals allowing wiring without tools for
rigid conductors or conductors equipped with end sleeves.
