Nature: Uncategorized Issue
Severity: 
Summary: The specification does not always define what happens in case I send a primary command to the SLM Main Unit (which would be delegated also to all Sub Units) but the main unit is not in the correct state. 

- The Main Unit should return the result code MAIN_STATE_INCORRECT and not call any Sub Units. 
T 
This is defined for some primary comamnds, but we should include a general statement into the spec to make this clear
Resolution: Add explanatory paragraph on page 2-10 at the end of chapter 2.3.5
Revised Text: Text added:
"In case a primary command is sent to the SLM Main Unit and the main unit is not in the correct state, the Main Unit returns the result code MAIN_STATE_INCORRECT and does not call any Sub Units."

Not forwarding invalid commands to the subunits makes a lot of
sense. It simplifies the error handling, state recovery, and shortens
the device's error response time. I'm in favor of adding a general
statement to the spec that requires command filtering at the SLM main
unit level.
