灵活、可靠以及低维护是EXA SC202G电导率/电阻率分析仪最突出的优点。其设计满足现代工业环境中苛刻的电导率测量要求，无论何种应用，其多样的性能均可以保证最高的精确性。
SC202的现场安装外壳符合IP65标准。SC202具有mA输出、数字通信(HART®、基金会现场总线H1、Profibus PA)以及清晰的LCD显示等特性，非常适用于工业应用。
各种各样的温度补偿能力: 符合IEC 60746-3标准的NaCl表，手动TC，预编程矩阵和自定义编程5×5矩阵，可以轻松实现高精度测量。再加上USP<645>23版中发行的纯水监视性能，使SC202非常适用于制药行业。
integrated control system, integrating DCS & PLC & 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
