以现代自动化控制网络进行讨论。系统有2个操作站,上位机计算机与PLC通过工业以太网通信,2台上位机计算机都装有以太网卡CP1613。管理层采用工业以太网通信,控制层采用Profbus-DP现场总线通信。西门子S7-300PLC和S7-400PLC作为PLC控制站,直流驱动器有西门子6RA70系列、艾墨生CT公司Mentor系列,交流传动装置有西门子6SE70系列、安川公司CIMR-G7系列,2台ET200M远程I/O站。本文将介绍4台6RA70、1台6SE70、2台远程I/O站与西门子S7-400PLC所构成的通信网络。
Discuss with modern automation control network. There are 2 operating stations in the system. PC and PLC communicate through Industrial Ethernet. 2 PC computers are equipped with CP1613 Ethernet card. Management uses Industrial Ethernet communications, the control layer uses Profbus-DP field bus communications. Siemens S7-300PLC and S7-400PLC PLC control station, the DC drive Siemens 6RA70 series, A Mexican company Mentor CT, AC drives Siemens 6SE70 series, Yaskawa CIMR-G7 series, two ET200M remote I / O station. This article will introduce four 6RA70, 1 Taiwan 6SE70, 2 sets of remote I / O station and Siemens S7-400PLC constitute the communication network.
