横河CS3000集散控制系统培训 1.硬件系统 1.1通信设备（Communication Devices） 1.1.1通信网关单元（Communication Gateway Unit） The communication gateway unit can be used for connecting the supervisory computer with the VL net of the control communication networks for the CS 1000 and Vnet of the control communication networks for the CS 3000 system. The models of communication gateway units available for CS 1000 system include the dual-redundant VL net and single VL net. The models of communication gateway units available for CS 3000 system include the dual-redundant V net and single V net. According to the applications, two models of communication gateway unit can be applied. They are the text-mode communication gateway unit (Model ACG10S-E) and the frame-mode communication gateway unit (Model ACG10S-F). 通信网关单元应用在CS1000的控制通信网VL net和CS3000的控制通信网Vnet中，这种通信模块被有效利用在CS1000的冗余VL net和单VL net系统中，也可用在CS3000的冗余V net和单V net系统中。根据需要的不同，两种不同类型的通信模块用将被支持，如文本模式通信顾网关单元(Model ACG10S-E)和帧模式通信网关单元(Model ACG10S-F). 1.1.2 总线转换器（Bus Converter） 1.1.2.1 V net总线转换器(Bus Converter for V net) Bus Converter for V net is positioned between the different domain numbered V nets, acting as an intermediary in communication between the human interface station (hereinafter referred to as the HIS) and control stations on the Control Bus of other domains. Using a Bus Converter, the control stations on other domains can be operated and monitored on the HIS. The V net bus converter supports two types, 10BASE-5 and 10BASE-2, of control bus interfaces. The V net bus converter that supports 10BASE-5 control bus interface is as follows: ? ABC11D-V: Bus Converter for Dual-Redundant V net The V net bus converters that support 10BASE-2 control bus interface are as follows: ? ABC11D-Q: Bus Converter for Dual-Redundant V net ? ABC11S-Q: Bus Converter for Single V net 1.1.2.2 Bus Converter for VL net Bus Converter for VL net is positioned between a V net and a VL net, acting as an intermediary in communication between the human interface station
