摘要
介绍了一种 BOPP薄膜生产线的 CC-link现场总线集散控制系统 ,系统采用三菱 Q0 2 CPU PLC,直流传动采用 5 90系列直流调速器 ,多种检测信号通过分布式 I/ O组件 AJ65 SBTB1-16D、F X2 N-3 2 CCL 等 ,经 CC-link传送至 PL C。简要介绍了 BOPP薄膜生产过程及 CC-link结构特点 ,由于该生产线连续作业 ,设备分布较分散约 80 m ,控制过程较为复杂 ,因此整个集散控制系统在功能上由 4个相对独立的子系统组成 ,即速度链传动控制系统 ,温控系统、测厚系统及辅助控制系统。实际应用表明该系统简洁、可靠 ,实时性强 。
The paper introduces a distributed control system based on CC-link fieldbus in the BOPP film product line. Mitsubishi Q02CPU PLC is used in the system and 590 series controller is used as its DC driver. Several measured signals are transmitted to PLC via CC-link and distributed I/O modules such as AJ65SBTB1-16D, FX2N-32CCL, etc. In this paper the process of BOPP film production and the characteristic of CC-link are introduced. Because the product line is continued working, its devices are spread around 80 meters, and its controoed process is complex. For above reasons, the distributed control system is consisted of subsystems with relative independent function. Viz. the speed chain drive control system, the temperature control system, the film thick measured system and the auxiliary control system. The actual application shows that the distributed control system is simple, reliable and good real-time. There is a powerful demonstration for the its further application.
