Hi Joel,
I posted the same message to answer one of your other questions.
The CANBeSafe blocks is outdated due to changes in the standards and removed from PLUS+1 GUIDE a while back.
To replace this there will be a new library coming out in the Update Center, the J1939 Safety FB Library V1.00.
These blocks can be considered the replacements for the old CANBeSafe blocks and will support the J1939-76 safety protocol.
Hopefully it will be uploaded to the Update Center any day now.
With this library there should be some user manuals for you to follow.
Have a nice day.
