PDP800 SymphonyTM Plus系统

在电力和水行业，没有其他的自动化平台能像Symphony这样拥有如此广泛的应用。在超过30年的时间里，ABB不断发展Symphony家族，保证新一代的产品在不断改进的基础上与上一代产品兼容—这和ABB一贯坚持的“渐进而不淘汰”政策一致。Symphony Plus拥有一套全面而标准的控制软件及硬件，以满足全厂自动化的需求。S+控制系统的 PDP800 PROFIBUS接口模件实现了HPC800控制器和Profibus设备相连接。这样就能够非常简便地集成智能设备，比如智能变送器、执行机构和智能电气设备(IED)。每种设备的内置信息都可以用于控制逻辑和更高层次的应用。
除了带来了更紧密和更可靠的过程控制解决方案，PDP800PROFIBUS方案能够减少布线和系统占地空间，从而节省系统安装成本。采用S+工程工具Composer来配置和维护PROFIBUS网络和现场设备，以及相关的控制策略，能够进一步降低系统成本。

智能现场设备无缝集成
S+控制系统的HPC800控制器通过PDP800 PROFIBUS接口模件无缝集成现场设备。这样就可以连接来自ABB和其他第三方供应商的包括变送器、执行机构、马达控制中心(MCC)、火焰监测设备、智能电子设备等在内的大量智能现场设备。PROFIBUS I/O和相关的HPC800控制策略可以使用ABB经过实践检验的功能码以及图形化的S+工程工具Composer来组态。此外，这些数据也可以经由冗余工厂网络(PN800)提供给其他的S+系统节点 (如：控制器、操作站、工程师站和信息站)。
PDP800 PROFIBUS接口模件的特性包括：
− PROFIBUS DP V0, V1, V2
− 通过DP/PA链接设备支持PROFIBUS PA 设备
− 支持PROFIBUS DP V2设备的1毫秒时间标签
− 支持电气和光纤介质的PROFIBUS DP 链路
− 高达12 Mbps 的PROFIBUS DP 链路
− 距离达15 km 的光纤PROFIBUS DP 链路
全面的I/O支持
PDP800模件帮助HPC800通过PROFIBUS DP V2来连接S800I/O。S800 I/O涵盖所有的信号类型，从基本的模拟量和数字量输入输出到脉冲计数和本安应用。S800 I/O的事件顺序功能支持PROFIBUS DP V2，并在采集源头标记1毫秒分辨率的时间标签。
此外，PDP800支持HPC800连接S+汽轮机控制专用模件。尤其，通过PROFIBUS V2，HPC800能够支持功能强大的汽轮机解决方案，包括：汽轮机保护(TP800)，阀门位置控制(VP800)，发电机自动同期(AS800)和状态监视(MCM800)。
采用光缆，PROFIBUS I/O模件和设备能够扩展到距PDP800模块15千米外。此外，PDP800模件也可以通过冗余HN800光缆通讯，放置到距离HPC800控制器3千米外。
高可靠性和可用性
PDP800支持所有层次的完全冗余，包括PDP800模件、电源、PROFIBUS DP链路，和控制器通讯总线(HN800)。所有的冗余选项都相互独立，以确保最高程度的可用性和可靠性。

PDP800A

SymphonyTM Plus is the next generation of ABB’s acclaimed Symphony family of decentralized control systems, the world’s most widely used DCS for the power generation and water industries. ABB has more than 6,000 Symphony systems in operation worldwide, of which more than 4,000 are used in the power generation and water industries.

In the power and water industry, no other automation platform has such a wide range of applications as Symphony. For more than 30 years, ABB has developed the Symphony family to ensure that the next generation of products is compatible with the previous generation on the basis of continuous improvement – in line with ABB’s consistent policy of “progressive, not obsolete”. Symphony Plus has a comprehensive and standard set of control software and hardware to meet the needs of plant-wide automation. The PDP800 PROFIBUS interface module of S+ control system realizes the connection between HPC800 controller and Profibus device. This makes it easy to integrate smart devices such as smart transmitters, actuators and smart electrical devices (IEDs). The built-in information of each device can be used for control logic and higher level applications.
In addition to bringing a tighter and more reliable process control solution, the PDP800PROFIBUS solution reduces cabling and system footprint, thereby saving system installation costs. Using S+ engineering tool Composer to configure and maintain PROFIBUS networks and field devices, as well as related control strategies, can further reduce system costs.

Seamless integration of smart field devices
The HPC800 controller of the S+ control system integrates seamlessly with the field equipment through the PDP800 PROFIBUS interface module. This makes it possible to connect a large number of smart field devices from ABB and other third-party suppliers, including transmitters, actuators, motor control centers (MCC), flame monitoring equipment, smart electronics, and more. PROFIBUS I/O and related HPC800 control policies can be configured using ABB’s tried and tested function codes and the graphical S+ engineering tool Composer. In addition, this data can be provided to other S+ system nodes (such as controllers, operation stations, engineer stations, and information stations) via the redundant plant network (PN800).
PDP800 PROFIBUS interface module features include:
− PROFIBUS DP V0, V1, V2
− PROFIBUS PA devices are supported by connecting devices through DP/PA
− Supports 1-millisecond time labels for PROFIBUS DP V2 devices
− Supports PROFIBUS DP links in electrical and optical media
− PROFIBUS DP links up to 12 Mbps
− Optical PROFIBUS DP links up to 15 km away
Full I/O support
The PDP800 module helps the HPC800 connect to the S800I/O via the PROFIBUS DP V2. The S800 I/O covers all signal types, from basic analog and digital inputs and outputs to pulse counting and intrinsic safety applications. The S800 I/O’s event sequence function supports PROFIBUS DP V2 and marks the time tag at the source of the acquisition with a resolution of 1 ms.
In addition, the PDP800 supports HPC800 connection to S+ steam turbine control dedicated modules. In particular, the PROFIBUS V2 enables the HPC800 to support powerful turbine solutions including: Turbine protection (TP800), valve position control (VP800), generator automatic synchronization (AS800) and condition monitoring (MCM800).
Using fiber optic cables, PROFIBUS I/O modules and devices can be extended up to 15 km away from the PDP800 module. In addition, the PDP800 module can also be placed up to 3 km away from the HPC800 controller through redundant HN800 cable communication.
High reliability and availability
PDP800 supports full redundancy at all levels, including PDP800 modules, power supplies, PROFIBUS DP links, and the controller Communication Bus (HN800). All redundancy options are independent of each other to ensure the highest degree of availability and reliability.
