| Message Passing Architecture: Moving a motor |
|
|
|
|
|
|
|
| Initiating
a move command |
||||||
| When a BLU-ICE user initiates a control |
||||||
| command, the
message must first pass |
||||||
| through DCSS
before being forwarded to |
||||||
| the
appropriate hardware server. |
||||||
| DHS
starts the motion |
||||||
| DHS receives the control message and |
||||||
| issues the
command to the controller |
||||||
| using the
protocol it understands. |
||||||
| Distributed
Hardware Servers (DHS) |
|
|
|
|
|
|
|
| Monitoring
hardware motion |
||||||
| Each Hardware Server is responsible for |
||||||
| updating DCSS
with the current position |
||||||
| of moving motors. |
||||||
| Synchronizing
BLU-ICE clients |
||||||
| DCSS will broadcast new positions for |
||||||
| motors and
changes in hardware status |
||||||
| to all BLU-ICE
clients. |
