The computer generates data for a prescribed run sequence to be carried out by the SYSTEM-90E.
With the pNET protocol, this task can be mastered with ease:
|
|
|
 |
The computer writes the data for the run sequence, for example, target
positions and velocities, into registers of SYSTEM-90E’s multi-port memory. |
|
Once the data are complete, SYSTEM-90E’s application program will be notified by setting a flag. |
|
Next, SYSTEM-90E will carry out the prescribed run sequence without further intervention. |
|
To inform the computer that the run sequence has been completed, another flag will be set. |
|
|
The way this example functions can be expanded at random.
|
|
|
| |
|
Two possible ways to expand this function: |
|
The computer will already be transferring data for the next run sequence
while the previous sequence is still being carried out. |
|
While the previous sequence is still being carried out, a register will inform the computer
of the sequence’s current status. |
