| ==== Purpose ====
| |
| The purpose of this example is to illustrate how to model a system with two standby devices with SCT.
| |
| | |
| ==== Statement ====
| |
| Assume that there are four devices A, B, C and D in the system. The system begins with A and B as active devices and C and D as standby devices. If one of the active device fails, one of standby device will be activated. After the active device is restored, it would become a standby device. For example, when A fails, C or D would be activated and become a active device. After A finishes repair, it would become a standby device.

| ==== BlockSim Solution====
| |
| It is easy to model this system with standby container. However, standby container has some limitations in other application. Here we want to model this system with SCT.
| |
| It is not possible to model this system directly with SCT. Here we present a alternative solution which can approximate this system.
| |
| | |
| The logic is like this: we will activate all standby devices whenever a active device fails. After activating all standby devices, we will
