摘　　要：自动定量包装机广泛应用于化肥、饲料、轻工等行业。目前,其控制系统大多采用传统硬PLC。软PLC技术是一种基于PC的新型控制技术,具有强大的网络通讯和数据处理能力,是目前自动化领域的研究热点之一。文章介绍了以德国3S公司的软PLC产品CoDeSys以及CAN总线为基础的分布式自动定量包装机控制方案,该方案可以实现自动称量和包装、产量统计、打印报表和远程监控等功能。Automatic const-weight packing machine has been widely used in chemical fertilizer, feed and light industry etc. Its control system is based on traditional PLC. SotfPLC technology based on PC is a new control technique and one of main research interests in Industrial automation field, which has stronger network communication and data processing capacity. The control system of distribute automatic const-weight packing machine based on CAN-bus and CoDeSys is introduced. It can be used to implement automatic const-weight packing, making a output statistic, printing report forms, monitoring remotely and so on.
