Rotork近日推出了用于油气行业控制阀门执行器的Rotork主站！
编译 | 惊蛰
Rotork公司推出了用于阀门触发器与工厂设备的最新一代创新型监控系统，可以用于油气行业的多种作业，帮助实现油气开发自动化。
Rotork站适用于油气行业所有作业，能够在三个及以上独立的现场网络上运行多达240个执行器，在工厂的不同区域都可以提供最佳网络应用。目前，它与第三方设备集成，可支持Modbus RTU协议，也可支持Rotork公司的标准双线式闭环系统Pakscan Classic，该系统现已安装于全球17万台以上的网络设备。
Rotork主站拥有诸多功能，可以管理与其相连的设备。无论是基于态的监控，还是预测性维护，Rotork都游刃有余。它还拥有大型触摸屏与基于网页直观的菜单结构，可快速提供设备设置、询问以及问题解决方案。
得益于多个主机连接与多个数据库的存在，Rotork主站能够最大限度地提高数据传输效率。通过热备用配置为主站提供内置的冗余支持，当主单元发生错误时，备份单元能够承担起网络控制。所有网络通信都采用容错保护，即使发生故障，设备也能够继续运行。
使用单根双绞线电缆取代了昂贵的多芯电缆，降低了安装成本与工序。有线控制回路可在长达12.4英里（20公里）的长回路上运行，无需外部中继器，进一步降低了人工、安装与调试成本。Rotork主站还可选配19英寸的机架或面板，所有接线都可以轻松地接入至前方的面板。
无需对网络或设备进行其他更改，Rotork主站可以替换现有的Pakscan IIE与P3主站系统，从而轻松集成至现有设备，并支持所有Rotork公司与第三方的驱动产品。Rotork主站提供从分布式控制系统（DCS）到现场设备的高完整性链路。它还配有一个大型触摸屏界面，使操作员与工程师可以随时查看系统和现场设备的确切情况。
备份Rotork主站可在组件发生故障时，维持系统的持续可用性。主机端口能够同时连接多个主机系统，并在必要时提供冗余通信链路。当发生故障时，主站可无缝切换至备用状态，不会造成数据与控制的丢失。

Suitable for use in all industries, the Rotork Master Station is capable of operating up to 240 actuators across three separate field networks allowing the optimum network to be used in different plant areas. It now supports Modbus RTU protocol with third party device integration and Pakscan Classic, Rotork’s standard two-wire closed loop system, which has more than 170,000 existing devices installed in networks around the world.
The Rotork Master Station has many features to enable the management of the assets connected to it. Whether the interest is in condition based monitoring or predictive maintenance, it is all possible with the Rotork Master Station. A large touch screen interface and web pages share the same intuitive menu structure focused on providing quick device set up, interrogation and issue resolution
Multiple host connectivity is included and the presence of multiple databases enables the Master Station to maximize data transfer efficiency.
The Master Station can be supplied with built-in redundancy support via a hot standby configuration, allowing a replica unit to assume network control in the event of an error in the primary unit. All network communications are secured with fault tolerance, allowing for plant operation to continue, even if a fault occurs.
Installation is low cost and simple through the use of a single twisted pair cable instead of expensive multi-core cabling. The wired control loops can operate on long loop lengths up to 12.4 mi (20 km) without external repeaters, further reducing labor, installation and commissioning costs. The Rotork Master Station is available with either 19 in rack or panel mounting options and all wiring is easily accessible from the front panels.
All Rotork and third party actuation products are supported while the Rotork Master Station can replace existing Pakscan IIE and P3 Master Station systems without the need for additional changes to the network or devices, allowing it to be easily integrated into installations.
Rotork provides service and commissioning support from all our global offices as well as online documentation that will assist commissioning, service and maintenance teams. Rotork offers training for customers in the Rotork Master Station and Pakscan networks, both in-house and on-site.
The Rotork?Master Station?provides the high integrity link from the Distributed Control System (DCS) to the devices in the field.
It comes complete with a large touch screen interface to allow operators and engineers to see exactly what is happening to the system and the field devices at any time.
A hot standby Rotork?Master Station?allows for continued availability of the system in the event of a component failure. Host ports allow connection to multiple host systems at the same time with redundant communication links where necessary. In the event of a fault occurring, the changeover to the standby is seamless without loss of data and control.
