摘　　要：现场总线是应用于工业生产现场的可以在数字化控制设备之间实现双向串行通信的控制系统。MODBUS现场总线是应用于电子控制器上的一种通用语言,它是一种通信协议。将其应用于滚塑生产(塑料制品的主要生产方式)中,对滚塑设备更新改造,可提升设备的智能化程度、生产工艺更加完善、产品质量进一步提高,同时增强了设备运行中的可靠性和稳定性,设备的可控性更强且操作更方便。着重介绍采用MODBUS RTU协议,将工控机、PLC、变频器等组成一个数控网络系统及其对滚塑设备智能控制程序设计中需解决的问题,同时,充分考虑到系统的实用性、经济性,开发程序时尽可能的利用程序代替外部硬件投入,争取企业效益最大化。Field bus is a controlling system applied in industrial operation which can realize two-way communication among controlling equipments. MODBUS field bus is a common language used for digital controlling machinery,which is a communication protocal. Applying it to rolling plastic production （main method of production of plastic product） to renew the equipment of rolling plastic can improve the degree of intelligence of the equipment, make the technology of production much better,improve the quality of product. Meanwhile, the reliability and stability of the equipment can be greatly improved. The control of the equipment will be much better and available. This paper mainly introduces how to organize a numerical controlling network system on the basis of engineering controlling apparatus, PI.C and frequency converter etc. adopting MODBUS RTU protocol,and,problems need to be solved in the design of the intelligence controlling program of rolling plastic equipment. At the same time,as the practicality and economization of the system is fully considered,program is utilized most possibly instead of outside hardware input when designing programs to try to gain the maximum benefit of a company.
