The next figure shows the interaction between the cycles and their effect on
command execution in the integrated technology:
The example shows the chronological order of execution across several position
controller cycles.
The time required for the various cycles is indicated in small time slices, and varies
with the number of configured technology objects. The time slices for the
interpolator cycle, interpolator cycle 2 and the technology DB update cycle are not
processed in all position controller cycles.
DP communication, the position controller cycle, interpolator cycle, interpolator
cycle 2 and the technology DB update cycle are executed with descending priority.
The command executing functions utilize the time interval between two position
controller cycles. The smaller this interval, the more time is left for command
execution.
