Abstract
This report describes interface standards applicable to the use of computer control systems with automated mining equipment. The report identifies. analyzes and recommends interface standards applicable to the modular control system of an Automated Extraction System (AES) being built by the U.S. Bureau of Mines (USBM). The work serves both as a technical guide and as a summary of existing and forthcoming standards applicable to computer control systems. Since the system configuration of the AES control system has not yet been defined, this report uses several alternative architectures to illustrate various interfaces that may be encountered. The benefits and limitations of the formal and de facto standards which apply to these interfaces are then discussed. In this context, standards are recommended for the supervisory computer-local control computer interfaces and the local control computer-sensor and actuator interfaces. The best use of these standards and important trade-offs are identified and explained.
