Junction Blocks

Junction blocks are non-failing blocks. Because diagrams must flow from a single starting point to a single ending point, you may need to use junction blocks as starting and/or ending blocks. (Diagram analysis constraints are presented in the Diagram Analysis Constraints topic.) They can also be used anywhere within the diagram that you need a block that does not fail (i.e., does not affect the system reliability).

You can add junction blocks to the diagram by choosing Diagrams > Diagram Tools > Add Junction.

Junction blocks do not have properties, so double-clicking the junction block or selecting it and choosing Diagrams > Format & Style > Edit Block > Block Properties will cause a message to be displayed indicating that the block does not have properties.
