This read-write value sets an up-to-8-character name for this node that must be unique across the network, and any change to it requires AutoRoute to propagate the new name to other nodes; it can also represent a PAR Feeder node's name. It gives operators a human-readable identifier for the node instead of relying solely on the numeric parSnNodeId. An admin renaming a node during a network audit needs to account for the propagation delay before other nodes recognize the new parSnNodeName.
