Description Setting
The Safety Network Number (SNN) provides a unique network
identifier for each network in the safety system and is generated by
the safety PLC.
Note
The user should assign SNN numbers for each safety network or
safety sub-net that are unique system-wide.
SNN
CAUTION
Originators (scanners) having an automatic SNN setting feature, i.e.
automatically generated data and time, can only use this feature
when the safety system is not being relied upon and is not in safety
state.
The configuration signature, also called Safety Configuration ID
(SCID) , uniquely identifies the configuration of the ABB CIP Safety
Adapter and can be used to confirm the integrity of the adapter
configuration over time.
Configuration signa-
ture
The signature is checked whenever an originator tries to connect
to the adapter. If the signatures match, the connection is established.
If the signature does not match, the error response
Configuration
signature mismatch is returned.
The signature is printed in the safety report and must be copied to
the safety scanner (PLC).
The following alternatives are provided:
• Not used - The configuration signature is not used.
• Auto generated - An automatically generated signature found
under "Configuration Signature - Date" , "- Time" , and "- ID"
in the safety report.
• User generated - A user defined signature. Alternatively, the
user can manually write the signature encoded as a 10 bytes
long hexadecimal string in the text-box below. The signature
can then be found under
"Configuration Signature checksum"
in the safety report.
Note
When configuring safety connections without the configuration sig-
nature, i.e. not used, the user is responsible for ensuring that origin-
ators (scanners) and targets (adapters) have the correct configura-
tions.
Note
The configuration signature should only be considered verified after
user testing. User testing is the means by which all downloads are
validated.
