The PublishingOffsetis defined in 6.3.1.1.6. The ValueRankof the PublishingOffsetshall be -3 if the Publishersupports scheduling of multiple NetworkMessagesper PublishingInterval. If only a single offset can be configured, the ValueRankshall be -1. Therefore, the Valueof the PublishingOffsetcan be a scalar value or a one-dimensional array value. The default Valueis scalar value.
