Description

TransferGate objects represent transfer gates in Safety Analysis Manager fault tree documents. Use TransferGate objects to reuse trees or subtrees in other fault trees.

Creation

To create a TransferGate object:

  • Use the createTransferGate function on a Gate object.

  • Get the TransferGates property of a FaultTree object.

  • Get the IncomingTransfer property of a Gate object.

Properties

expand all

Gate in the Safety Analysis Manager fault tree that the transfer gate retrieves, specified as a Gate object.

If you evaluate a fault tree document that contains the transfer gate and this property is empty, the fault tree document sets the transfer gate failure unavailability and frequency to 0.

If you specify a gate that implements a logical loop, an error occurs.

Examples

collapse all

Create a new fault tree document in the Safety Analysis Manager and get the FaultTree object.

myTreeDoc = safetyAnalysisMgr.newDocument("fault-tree");
myFaultTree = myTreeDoc.FaultTrees(1);

The new document contains one fault tree. Create another fault tree and store the associated FaultTree object.

myNewTree = createFaultTree(myTreeDoc);

Add a transfer gate to the top-level gate of myFaultTree that transfers from the top-level gate of myNewTree.

topGate = myFaultTree.Gates(1);
newTopGate = myNewTree.Gates(1);
myTransferGate = createTransferGate(topGate);
myTransferGate.Gate = newTopGate;
