Can I use a standby container in BlockSim 8 if the blocks in one of the paths are not connected in series?
In a standby redundancy configuration, the redundant components are set to a dormant (quiescent) state while they are not needed, and are available to become active under specified circumstances (e.g., when one or more active components fail). In BlockSim 8, using a standby container in a reliability block diagram (or a standby gate in a fault tree) is the simplest way to model a standby configuration. The container has one or more active paths and one or more dormant paths; each path in the container can consist of a single block or of multiple blocks connected reliability-wise in series.
If you need to use a parallel or complex configuration as a path within a container, you can do the following:
- Create a diagram that models the required path configuration and analyze or simulate the diagram.
- Publish the results as a model.
- Create a URD that uses the model.
- In the container, add a contained block and define it with the URD that you just created. Now this single block will represent the parallel or complex configuration that you defined in the separate diagram.
In the example shown next, the active path in the standby container consists of Block 2 and Block 3 connected in series. The standby path consists of Block 4, which uses the published model that represents the parallel configuration that has been defined in a separate diagram.
