The master may only send
new commands
to the slave (MOBYĆASM) when the
ASM is ready. The MOBYĆASM's readiness is indicated with cyclic state info. The
same applies to acknowledgments. The MOBYĆASM may only fetch
new
acknowledgments
when a new acknowledgment is actually waiting (i.e., has not
yet been read). This information is also indicated with a state info.
Two indications are defined in the state info. The PROFIBUSĆDP master uses
these two indications to decide whether a DP/V1 telegram can be executed to or
from the MOBYĆASM.
