Some Interactions of Information and Control in Integrated Automation Systems

摘要: The ready availability of inexpensive and standard communications hardware in the late 1980s, coupled with sufficient standardization intermediate-layer protocols to make reliable machine-to-machine communication through any combination devices a reality, has laid groundwork for integrated automation on grand scale. contribution Manufacturing Automation Protocols (MAP) effort [MAP87], thus far, been speed delivery this powerful capability industrial community. We must realize, however, that now outstripped our ability use it. On factory floor, we have no which are prepared control scale, even worse, few controllers capable contributing their local kind whole. stumbling block is lack common languages or experience base communicate about tasks. midst flurry intellectual activity, both sides Atlantic, developing languages, architectures, techniques, data systems, systems ultimately meet challenge. In such burst it be expected experts individual areas will hasten solve problems they most conversant, certain interdisciplinary fail get timely attention. It purpose paper draw attention several issues now, hope may due consideration as process advances. discussed here are: separation flow from flow, the impact perfect real-time control, consistency physical reality, the significance models, the identification shared private data.
