High priority programs each have a dedicated time slice, where the low priority programs share a time slice. Communications also have a dedicated high priority task. Each time slice is 1ms, within that time the programs will execute anywhere from 1-10 lines of code before switching to the next program in the queue.
An example of the operation order where 0-9 are all being used would proceed as follows:
0,1,2,3,4,5,6,7,COM,8
0,1,2,3,4,5,6,7,COM,9
0,1,2,3,4,5,6,7,COM,8
Notes:
-
Programs will only utilize their time slices when they are actually running.
-
The program priorities are fixed in the controller, there is no provision for adjusting the priorities for the user.
-
DWL statements in low priority programs will cause the entire low priority slice to DWL
-
INH statements in low priority programs will inhibit the entire low priority slice
-
PROG15 is used by the ACR-View to store the configuration. Users should avoid using this program for other purposes.
