Bringing deterministic industrial networking to the W3C web of things with TSN and OPC UA

A Survey on the Web of Things

“…Despite the standardization process for the TD [69] is at the conclusive phases, researchers have made several proposals to enhance its descriptiveness on specific application domains. For instance, Sciullo et al [130] introduce a special vocabulary for handling QoS guarantees in the TD, as a bridge towards industrial protocols and deterministic networking. In the same direction, Korkan et al [82] propose a new vocabulary for TD to describe the sequential behavior of a WT associated to a controller.…”

“…In this Section, we review the main enabling technologies of WoT deployments, by distinguishing between: (i) basic enablers, constituted by data formats, protocols, and programming languages (Section V-A), and (ii) tools of the WoT SECO, further classified based on the phase of deployment in which they are used (Section V-B), and referring almost exclusively to the W3C WoT.

Integrating Multi-Disciplinary Offline and Online Engineering in Industrial Cyber-Physical Systems through DevOps

“…Industrial networks are often multi-tiered, formed by a combination of TCP/IP, Industrial Ethernet (e.g., EtherCAT), and classical fieldbuses (e.g., MODBUS over RS-485). The communication bus needs to be established to enable the devices to join the local network while considering Quality of Service (QoS) requirements, including IEC/IEEE 60802 Industrial Automation profile for Time-Sensitive Networking (TSN) capability in the data link layer, and such network management is also possible through TDs [45]. At the time of writing, the OPC Field Level Communication (FLC) initiative 8 is working on the OPC Field eXchange (FX) standards to extend the OPC UA information model to the field level by describing functional entities and connection managers of devices and controllers with AML.…”

Towards Provenance Integration for Field Devices in Industrial IoT Systems

“…In the WoT architecture, Protocol Bindings define the mapping between affordance and concrete protocol message. Although, only an HTTP binding is currently standardized [5], further development is expected to support field level industrial protocols such as OPC UA and NETCONF for Time-Sensitive Networking (TSN) [13].…”
