The resulting CPU load in Advant Controller 450 from one MasterView 320 is given in
Figure 3-13.
On the X-axis you can find the update requirement from a display, which is SUHVHQWHGRQWKH
VFUHHQ. Note that the load caused by, for example, 20 variables updated every second is the
same as the load from 40 variables updated every other second. If several MasterView 320 is
used at the same time (with a display on screen) you have to add the load figures from each
terminal.
