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。
elected for the system bus
Due to the adoption of tcp/ip protocol, the system can also realize ultra long distance communication with the help of public telephone network (dial-up mode) or satellite.
PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination
Discussion.
The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control
All schemes can be realized by the combination of these function blocks.
The function blocks provided by the system mainly fall into the following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop adjustment
Logical sequence control
c
Logical operation
Monitoring function
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface
1ec870-5 protocol communication interface (telecontrol)
4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
