基于SIMATIC NET的数控磨床车间SCADA系统设计

Design of SCADA System for CNC Grinder Workshop Based on SIMATIC NET

针对公司对数控磨床车间的掌控力度不足问题,提出了基于西门子通信技术的数控磨床车间数据采集与监控系统,通过SIMATIC NET工业以太网,实现SIMATIC NET OPC服务器与西门子数控系统中的S7系列PLC进行数据交换,进而利用SIMATIC NET所提供的通信模块把数据提供给SIMATIC NET OPC客户端;在数控磨床车间SCADA系统中,采用WinCC作为SIMATIC NET OPC的客户端,同时开发了基于VB高级语言的SIMATIC NET OPC客户端,以增加SCADA系统的功能;基于SIMATIC NET的SCADA系统实现了对数控车间的数据采集与设备监控,为公司下阶段的信息化建设奠定了基础。

In order to solve the problem of insufficient control of CNC grinder workshop,a SCADA system based on SIMATIC NET for CNC grinder workshop is proposed,which is based on SIMATIC NET industrial Ethernet.The data exchange between SIMATIC NET OPC server and S7 series PLC in Siemens NC system is realized,and then the data is supplied to SIMATIC NET OPC client by using the communication module provided by SIMATIC NET.In the SCADA system of CNC grinder workshop,WinCC is used as the client of SIMATIC NET OPC,and the SIMATIC NET OPC client based on VB language is developed to increase the function of SCADA system.The SCADA system based on SIMATIC NET realizes the data acquisition and equipment monitoring of the NC workshop,which lays a foundation for the next stage of the information construction of the company.
