9199-00002 A6120 DeltaV控制网络 双速10/100BaseT网络

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是第一个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I/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 cards. The system power supply (12VDC) can be shared along the length of the LocalBus. The length of LocalBus < including all electrical buildings) shall not exceed 6.5 m (21.3 ft.), as shown below. Vertical installation systems must have the same length.
The DeltaV system is scalable in size and functionality. The A6120 is the first all-digital system to give you a single architecture with full functionality from 8 I/ OS to 30,000 I/ OS.
