SCT with delay
Purposes
The purposes of this example is to illustrate how to apply SCT with delay.
Description
Three devices A, B and C are in parallel. 2 out of 3 are required to perform the task. Initially A and B are working, C is in standby status. If A or B fails, C will replace the failed one with some delay. After the failed device is restored, it will become a standby device. For example, If A fails, with 10 hours delay C will become active and replace A. After A is restored, it will become a standby device for B and C.
BlockSim Solution
The BlockSim modeling of this system is shown in Figure below.
In order to model the delay, three extra blocks AA, BB and CC are added to the diagram.
