Absolute network disconnector between socket A and B:
1
a) If A and B belong to different local Ethernet interfaces (for example, X1 and X2) and no bridging is implemented at
communication level 2 for these interfaces.
a) If either A or B are part of a local Ethernet interface and the other is part of a backplane bus module with an Ethernet
interface (CP, CM), and no bridging is implemented at communication level 2 for these interfaces.
No network disconnector between socket A and B:
2
a) If A and B belong to the same local Ethernet interface (for example, X1).
b) If A and B both belong to a backplane bus module (CP, CM).
Even when using a communication network disconnector according to IEC 61784-3-3 (PROFIsafe standard), you must still
ensure that the individual isolated networks are not connected by other standard components. See also this FAQ
(https://support.industry.siemens.com/cs/ww/en/view/109740240).
Standard CPUs are generally not network disconnectors according to IEC 61784-3-3 (PROFIsafe standard).
Support of PROFIsafe V2 for PROFINET IO
Interfaces that support PROFINET IO also support PROFIsafe V2.
Support of PROFIsafe V2.4 for PROFIBUS DP
Interfaces that support PROFIBUS DP also support PROFIsafe V2.4 but not PROFIsafe V2.6.
Restriction with "CREAT_DB" and "DELETE_DB" instructions
F-DBs can neither be created nor deleted.
Restriction with "READ_DBL" and "WRIT_DBL" instructions
The destination address must not point to an F-DB.
