For general information on the OPC UA Companion Specification Mining and OPC UA in general, please refer to OPC 40560.

As explained in OPC 40560, the machine and system category-level documents serve as an abstraction layer for the types of machinery with similar functionalities. Consequently, this machine and system-level document may also rely on models defined in OPC 40567-1.

In longwall mining operations, a shearer, armoured face conveyor, roof support system and other components are used for the extraction of raw material. The FAS is usually a software component that is used to automatically straighten the conveyor line in respect to an aerial view of the longwall face. This way, the FAS, can instruct the RSS to align its shield positions by a certain offset.

This document contains OPC UA type definitions for the armoured Face Alignment System.
