Running Multiple Applications
with the XMP
|
There are two situations
that often cause problems when you are executing multiple
applications at the same time:
|
|
|
- If one application resets the XMP controller
while other applications are busy using the XMP,
this is analogous to pulling the rug out beneath the
feet of the other applications. The other applications
are not aware that all states have been lost (controller
reset), and thus these other applications get lost
themselves.
If you run two XMP applications at the same time (Motion
Console and VM3, or Motion Console and your application),
and if one application resets the board while the
second application is busy accessing memory (like
VM3), then the interface between the host and DSP
can break down. To resolve this type of problem, you
should close both applications, restart one application,
and then reset the XMP.
- If you modify the default configuration of
objects on the XMP, and then run another application
which wants a different configuration of the
same objects (program sequencers, motion supervisors,
axes, etc), and you don't manage this, you can get
into trouble.You have to coordinate how simultaneously
exectuing applications manage the XMP resources.
- Simultaneously, using DLLs, applications, and Motion
Console from different MEI releases can and
will cause problems.
