You use the Set Repeated Block window to indicate whether the block is a repeat of another block in the diagram. If the Repeated checkbox is cleared, no repeat is set, and the Same As list is unavailable. If this checkbox is selected, the block is a repeat of the block selected in the Same As list. This list includes the unique identifiers of all other blocks in the diagram. You can view the identifiers assigned to blocks in either the diagram or the RBD Blocks Table.
