Down-Link
Down-Link
An industrial Downlink, in the context of data communications and industrial networks, refers to a connection that originates from data communications equipment, often a master device, and is directed towards data terminal equipment, typically wireless devices or nodes within an industrial network. This downlink is responsible for transmitting data or instructions from the higher-level or superordinate system to the downstream IO-Link Wireless Devices (W-Devices). It is a unidirectional data flow from the network core or higher-level nodes to edge terminals or nodes, and is commonly associated with the process of downloading data. The Downlink is facilitated by sending Multicast-W frames with data for the W-Devices in assigned time slots and is an integral part of the transmission cycle in industrial communication systems, with measures like Frequency Hopping and Channel-Blocklisting used to secure the transmission.
