Security and Password
Guardmaster 440C safety relay security has two components:
• Exclusive access that prevents simultaneous configuration of the safety
relay by two users.
• Password protection that secures the intellectual property that is
contained within the safety relay and prevents unauthorized access.
Exclusive Access Exclusive access is enforced on the Guardmaster 440C safety relay regardless of
whether the safety relay is password-protected or not. This means that only one
Connected Components Workbench (CCW) session is authorized at one time
and only an authorized client has exclusive access to the safety relay application.
This helps ensure that only one software session has exclusive access to the
Guardmaster 440C application-specific configuration.
Exclusive access is enforced on Guardmaster 440C firmware version 7 and later.
When a CCW user connects to a Guardmaster 440C safety relay, the software is
given exclusive access to that safety relay.
Password Protection By setting a password on the safety relay, you effectively restrict access to the
configuration software connections to the safety relay to software sessions that
can supply the correct password. Essentially, CCW operations such as upload,
download, and connect are prevented if the safety relay is secured with a
password and the correct password is not provided.
Guardmaster 440C safety relays with firmware version 7 and later are shipped
with no password. A password can be set through the CCW software (version 7
or later).
The safety relay password is also backed up to the memory backup module (Cat.
No. 2080-MEMBAK-RTC).
