A number of applications of communication links are dealt with below. The communication link
itself will give rise to a small controller CPU load. This load is specified for each application
and should be finally added when the individual sending/receiving is considered.

The capacity of the communication link must also be considered in a performance
calculation. See separate documentation attached the used link.

Data set peripherals (DSP) are cyclically transmitted to their respective destinations, with a
cycle time selectable in the range 32 ms to 4096 ms.
The Advant Controller 450 CPU load from data set peripheral communication can be estimated
from the curves given in Figure 3-16 and Figure 3-17.
