Abstract
At present, PLC is in the industrial automation control domain throughout the main battlefield, new PLC system in stable reliable and low failure rate foundation, strengthened the computation speed, the communication performance and the safe redundant technique. The PLC technology's development will be able the more satisfied industrial automation need, to be able to provide safe reliable and the quite perfect solution for the automated control application. This article mainly introduced rubs the stone powder production line control system design. Rubs the stone powder production line mainly by the limestone high-quality goods system, the scratch system, the lime stone powder transportation and the storage and transportation system, the pneumatic system and the cooling aqueous system five parts is composed. In this paper will give the detailed explanation to various part of designs, because the time adds on myself level to be limited hastily, the deficiency is unavoidable, but also invites the professional and teacher criticizes points out mistakes.
