1 Scope

NB/T 11118.2-2023 is Part 2 of the Chinese standard for EtherNet/IP communication between the machines on a fully mechanised longwall coal face, and it defines the extended object library. A fully mechanised face carries a shearer, powered roof supports, an armoured face conveyor, a stage loader, crusher and pumping station, supplied by several manufacturers, and they only work as one system if they describe themselves in the same language on the network. Where Part 1 fixes the physical interface and the protocol profile, this part fixes the objects: the data structures each class of equipment exposes, their instance and class attributes, the services that may be invoked on them, the data types and value ranges of each attribute, and the error codes returned when a request cannot be served. The library covers maintenance and operating modes, the shearer and its cutting and haulage parameters, the roof supports and their advance and setting states, the conveyor and its drives, the pump station, and the sensors and protection devices that report from the face. Each object is specified so that a control system can discover, read and command any conforming device without vendor-specific code. It applies to the design of equipment and control systems for fully mechanised coal faces in China, and is the text against which interoperability is judged.

This document specifies the object library for the EtherNet/IP communication of the mechanical and electrical equipment of fully mechanized coal mining faces, including the object specification and the specific description of the objects of the mechanical and electrical equipment.

This document is applicable to the object definition of shearers, hydraulic supports, fluid supply systems, scraper conveyors together with beam stage loaders and crushers, mobile substations, low-voltage AC vacuum feeder switches, multi-circuit low-voltage AC vacuum electromagnetic starters, low-voltage AC vacuum electromagnetic starters, and integrated lighting and signal protection devices.
