Examples

Figure 1 presents an example where the TIME component is used to switch a pump off between 5:00 and 21:00 and on between 21:00 and 5:00 every day. Figure 2 (a & b) shows the output of the MOD and OR component for a simulation duration of 1 week.

Component TAB2 is used to translate logical output to a pumpspeed including start/stop time in 5 s. Figure 3 shows the pump speed.
