A6120 DeltaV控制网络是连接DeltaV工作站和控制器的标准以太网。控制网络是双速10/100BaseT网络。CAT5屏蔽(ScTP)双绞线电缆将每个节点
连接到集线器或交换机。
LocaBus,A6120由电源控制器载体上的内部电源总线、相关IV/O接口载体上的总线和连接电缆组成。LocalBus为控制器和V/O子系统供电,并提
供卡之间的通信连接。系统电源(12VDC)可以沿LocalBus的长度共享。LocalBus的长度〈包括所有电筑)不能超过6.5 m (21.3 ft.),如下图所示。垂
直安装系统的长度要求相同。
DeltaV系统在尺寸和功能上都可以扩展。A6120是为您提供单一架构的全数字系统,具有从8个I/O到30,000个/O的全部功能。
The A6120 DeltaV Control Network is the standard Ethernet for connecting DeltaV workstations and controllers. The control network is
a two-speed 10/100BaseT network. CAT5 Shielded (ScTP) twisted pair cables connect each node to a hub or switch.
The LocaBus, A6120 consists of an internal power bus on the power controller carrier, a bus on the associated IV/O interface carrier,and
a connecting cable. LocalBus supplies power to the controller and V/O subsystem, and provides communication connections between
