GE关键控制系统的核心是Genius模块冗余(GMR)，综合了系列90-70 PLC和已经过现场考验的Genius l/0。这些都是经过时间考验的组件：全球安装了2万多个系列90-70 CPU和超过一百万个Genius模块。易于获取的GMR模块提供了一种可升级的解决方案，可使客户将冗余等级与风险等级相匹配。 PACSgstems冗余系统解决方案是整个控制操作的唯一系统，不必为其他应用和外部系统间的数据同步进行复杂的准备。使用GE的用户友好型软件解决方案Proficg Machine Edition可使组态、安装、监控和维护简单化，无需编程即可实现冗余切换功能。使您具备以下能力：
利用先进的面向对象编程显著减少编程时间和成本
使用冗余向导轻松设置硬件组态，为冗余方案进行正确的参数设定
使用简单直观的工具在线调试和监控您的系统
通过冗余传输列表的运行模式存储支持在不间断的前提下添加、删除或修改传输输入序列
由于利用了在主次以太网控制器间浮动的内置冗余lP，使H Ml/SCADA级的处理器切换透明化——简化开发过程并不再需要副本数据库。
Field Bus;
2. Using RISC SuperScalar high-speed CPU, with super performance;
Three high reliability, strict industrial application practice, more than 1000 sets of application performance in China;
4. It has good openness, flexibility and scalability;
Fifth, the project is easy, the interface is friendly, and the maintenance is simple;
2. Industria1″ system communication
Industrial” system uses international standard industrial bus. Field controller supports Profibus, FF, ModBus, Can, etc.
International standard fieldbus, Profibus is the most widely used open fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
discussion.
The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
