Hello,

I would appreciate if someone could help me with the interpretation of the
ASTM standard regarding the STATE_CHANGED message, in particular for the
POWERED UP state.

According to 7.4.1.1 the SLM connects to the TSC, then changes to POWERED
UP, and needs to announce this with a STATE_CHANGED message.
On the other side, POWERED UP is the very default state (that of Control
Flow, which is the entry state of Operating, which is the entry state of the
top level state), from where connection to the TSC is started (6.1.1) and
from where state changes must be due to commands or event reports (7.3.1).

I think there is a contradiction between 7.4.1.1 and the other sections
dealing with POWERED UP and the state changed message, and I'm not convinced
that the state changed message should be sent (in the same way as the entry
in LOCAL CONTROL doesn't need to be announced) as at that point the SLM
hasn't really changed a state in a current interaction (7.5.1). The TSC can
always query the status of the Control Flow interaction if it wants to know
what state the SLM is in.

Does anyone agree/disagree?

Best regards,

Dorothe Steidinger
