2.3 网络构成及硬件介绍
如图1所示,在该系统设计中有两个网络使用了上海泗博自动化的Modbus转Profibus-DP网关PM-160。网关在这两个网络中的作用不一样,其中:
在上层网络中(建立西门子S7-300PLC和横河DCS连接通信),Modbus转Profibus-DP网关PM-160在Modbus侧做Modbus从站,在Profibus-DP侧做从站,建立Profibus-DP主站(西门子S7-300 PLC)和Modbus主站(横河CS3000)的通信。DCS通信部分采用横河型号为ALR121的通信模块,并配套横河提供的Modbus通信软件包,该通信模块大通信数据容量为4000字。通过上海泗博自动化的网关配置软件对PM-160进行相关配置,将DCS的读、写指令及数据做相应转换、存储,并映射到西门子PLC的输入、输出映像区,以实现对上下位机控制信息的实时传输。
在下层网络中(建立西门子S7-300PLC和现场智能仪表的连接通信),Modbus转Profibus-DP网关PM-160在Modbus侧做Modbus主站,在Profibus-DP侧做从站,建立Modbus从站(现场各种智能仪表(现场电机、智能开关、变频器、传感器等))与Profibus-DP主站(西门子S7-300PLC)的通信。串口网络(现场智能仪表)设备接口为RS485或者RS232,它们都可以通过上海泗博自动化的Modbus转Profibus-DP网关PM-160实现与西门子S7-300PLC的连接通信。其中,通过使用网关的配套配置软件对PM-160进行相关配置,将需要采集的从站设备信息通过网关读、写命令及数据转换、存储,映射到西门子PLC的输入、输出映射区,以实现PLC对现场智能仪表数据的采集和监控。
三. Modbus转Profibus-DP网关PM-160的配置
PM-160是通用型Modbus/RS485/RS422/RS232到Profibus-DP的协议转换网关,在网关RAM中建立了Modbus/RS485/RS422/RS232到Profibus-DP的映射数据区changing the mold according to the needs of different specifications of products. A large number of plastic cylindrical wires are continuously transported to the host part. The temperature requirements in different areas of the host part are different. The plastic wires are processed by molds to form plastic molded products with a certain thickness and width. Then cut according to the set cutting length, so as to produce plastic mesh mattress products with different length, thickness and width. Delta has effectively integrated its automation products and successfully applied them to the control system of plastic mattress forming machine. Shanghai No.2 Textile Machinery Co., Ltd. is one of the large enterprises specializing in the manufacturing of textile machinery and textile equipment. The company has been established for nearly 90 years and has been committed to the R & D, production and sales of various textile machinery equipment such as cotton spinning frame, roving frame and automatic winder all year
