Fan-out connection using aliases (branching a single output NV to two or more input NVs on this
interface card) should be avoided because the interface card may miss-fetch any input NV depending
upon the fetch timing. If it cannot be avoided, use the repeated mode for the connection messaging
service to prevent miss-fetch of the branched NV aliases.
