Description of the RFC 4072S
108580_en_02 PHOENIX CONTACT 27 / 272
Device identification/
number of safe devices
In PROFIsafe, safe devices (F-Devices) are identified by means of F-addresses, which must
be assigned uniquely for each safe device. PROFIsafe destination address F_Dest_Add
(F_Destination_Address) is used to uniquely identify safe devices. This address is defined
in the PLCnext Engineer software and checked immediately after it is entered in
PLCnext Engineer. PLCnext Engineer checks the entered addresses for uniqueness in the
configured network and for correct value range.
The value of the F_Destination_Address can be set from 0
dec
to 65535
dec
. It must be unique
throughout the entire network.
Source address F_Source_Address (F_Source_Add for short) uniquely identifies the F-
Host of a communication relationship. The F_Source_Address is assigned to the safety-
related controller and is used for all communication relationships that are assigned to this
SPNS. In this way, the RFC 4072S obtains a source address (F_Source_Add).
The value of the F_Source_Address must be between 0
dec
and 65535
dec
and must be
unique throughout the entire network.
A maximum of 300 F-Devices can be connected to a RFC 4072S.
This results in the following maximum values:
– The sum of all bytes of safe input messages must not exceed 8192 bytes (input user
data and PROFIsafe backup data in “Characteristic data of the safety-related
PROFINET controller iSPNS 3000” on page 228).
– The sum of all bytes of safe output messages must not exceed 8192 bytes (output user
data and PROFIsafe backup data in “Characteristic data of the safety-related
PROFINET controller iSPNS 3000” on page 228).
For safety modules from Phoenix Contact, you can set PROFIsafe destination addresses
from 1 to 999
dec
, maximum. For safety modules from other manufacturers, you can set
PROFIsafe destination addresses from 1
dec
to 65534
dec
.
NOTE:
Please note that each F-Address assigned within a network must be unique and must not
overlap with other addresses.
