二、采用RISC SuperScalar高速CPU,具有超级性能;
三高可靠性,严格工业应用实践,在中国1000 余套应用业绩;
四、具有良好的开放性、灵活性及扩展性;
五、工程容易,界面友好,维护简单;
2、Industria1″系统通讯
Industr ial”系统使用国际标准工业总线。现场控制器支持Profibus、FF、ModBus、 Can等各种国
际标准现场总线,Profibus 是目前世界上应用最广泛的开放型现场总线国际标准,分为FMS、DP及PA
三级,DP通讯速率可高达12Mb。Profibus用于连接分布式I/0站及现场总线仪表等智能设备。
过程站、操作员站及工程师站之间的通讯是通过系统总线DigiNetS (工业以太网)实现的。用户
可以为系统总线选择不同的传输介质(RJ45 双绞线、细缆、粗缆或光纤电缆以及混合介质)和网络拓
朴布局,由于采用TCP/IP协议,系统还可借助公共电话网(拨号方式)或卫星实现超远距离通讯。
PLC等子系统则通过ModBus协议接口与Industrial”系统进行通讯。系统还支持IEC870-5過控协

DP and PA, DP communication rate can be as high as 12MB. Can (din/is011898 standard) bus
The biggest feature is its super robustness and data security. The system also supports MODBUS. The communication with intelligent field instruments is through
IART protocol or fieldbus (31.25kb profibuspa and FF Bus).
The system communication between the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard),
The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application.
Popular PC and MS_ Wi ndows2000 has been widely used in various fields all over the world and has become the de facto standard computer platform
Set. The operating station 0s, engineer station es and data gateway GS of the industrial “system have adopted this platform, thus ensuring the
It is universal, open and easy to use, and brings great convenience for future technology upgrading and maintenance.

System engineering configuration is very convenient. The configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
(LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes. The system contains about 220 functions
The algorithm library of energy block, the basic library with more than 200 graphic symbols and the extended library with a large number of 3D symbols.
The system uses the same set of configuration tool software to complete the configuration and commissioning of process level, operation level and even fieldbus instruments, and uses the same
A global database.
