3.2 MOBY commands
Programming
There are two programming methods.
• Reading (processing) each MDS which comes by. After the ASM is programmed with a
Figure 3-2
When permanent command repetition is used, data may be transferred to the FC 45 slower
than new MDSs are being processed (fast MDS sequence, slow data transmission). In such
cases, the results are intermediately stored on the ASM. The ASM has a number of buffers
for this intermediate storage. When the buffers are full and the FC 45 has not fetched data
and additional MDSs arrive, these MDSs are no longer processed.
