The method commonly used when accuracy is desirable is based on an analysis of
I/O, PC, Communication, and so on, part by part, to obtain load figures for each part and the
complete system.
Another shortcut method to analyze the CPU-load is to work with estimated application
functions of varying complexity.
Forms to be used in your own practice are given in Appendix F, Load Calculation.
For execution times to use in analyses and estimations of CPU load, see Section 3.2, Technical
Data Including Capacity & Performance. See the manual3&(OHPHQWfor detailed information
regarding execution times for the individual PC elements.

The performance of redundant processor modules is reduced to 95% in relation to a single
system. Divide all load figures given by 0.95.
