When the peripheral port is being used in the example above, the calcula-
tion result is negative and the CompoBus/S wait time is negligible.

2. The cycle time can be read from a Programming Device.
3. AR 14 contains the max. cycle time and AR 15 contains the current cycle
time.
4. The actual cycle time will vary slightly from the calculated value due to vari-
ations in processing from cycle to cycle.
If the cycle time is shorter than the CompoBus/S communications response
time, the actual cycle time will be equal to the CompoBus/S communications
response time. With short cycle times, the CompoBus/S communications
response time will become the minimum cycle time; this is especially true
when long-distance mode is being used.
