先进性设计和特点
（1）0-57C406-E采用了高性能的PowerPC芯片，控制器最快控制周期为5ms；控制器与I/O卡件采用eBus直接通讯，12个本地分支满负荷配置下读写I/O数据的时间在10ms以内；控制器采用eNet协议降低了通讯负荷，提高了通讯速度，读写控制网络的时间在200ms以内。
在以上三种技术基础的支持下,0-57C406-E的操作响应周期小于700ms。700ms的操作响应周期指标大大优于目前2.5s的行业标准，是符合人体工学的最高标准，将操作人员从画面操作的停顿等待中解放出来，能够改善操作人员的操作感受，提高运行操作效率。
With the support of the above three technological foundations, the operation response cycle of NT6000 is less than 700ms. The response cycle index of 700ms is significantly better than the current industry standard of 2.5s, which is in line with the highest standard of ergonomics. It frees operators from the pause and waiting of screen operations, improves their operating experience, and enhances operational efficiency.
The KM950 controller of NT6000 is currently one of the most powerful controllers in the industry in terms of computing power. It performs 1000 PID operations at a cycle of 100ms for testing, occupying only 2% of the computational load. Powerful computing power enables control engineers to implement various advanced control algorithms and sophisticated logic designs.
The configuration tool of KM950 provides a rich range of thermal automation professional control modules, including equipment level control, compensation algorithms, and typical circuit control. Moreover, it also provides powerful module secondary development capabilities, allowing engineers to write various custom modules using IEC standard development tools and incorporate them into the NT6000 standard algorithm library.
All components in the cabinet are connected using preset modules, reducing manual wiring, not only reducing labor costs, but also improving system reliability and maintenance convenience. Modular designed cabinets can be quickly assembled and disassembled with just a screwdriver. The cabinet design scheme fully utilizes the wiring space on the front and back sides of the cabinet, which is a perfect combination of maximum wiring density and the most loose wiring space.
Progressiveness design and characteristics
The NT6000 adopts a high-performance PowerPC chip, and the fastest control cycle of the controller is 5ms; The controller communicates directly with the I/O card using eBus, and the time for reading and writing I/O data under full load configuration of 12 local branches is within 10ms; The controller adopts the eNet protocol to reduce communication load and improve communication speed, with a read and write control network time of less than 200ms.
he NT6000 decentralized control system has offline simulation function. Through virtual controller software, 64 controller nodes can be simulated simultaneously on any PC, and simulation controllers on different PCs can communicate with each other. At the same time, simulation controllers can also communicate with real controllers, and their functions and network characteristics are completely consistent with real controllers. The virtual controller software has the function of simulating the freezing, saving, restoring (rolling back) of the controller's working conditions. Combined with the model software, it is easy to form a virtual DCS simulation system.
The NT6000 system cabinet and its various components are all designed with modular standards, and there are no manual wiring inside the cabinet. This standard cabinet can be factory produced to ensure higher quality, shorter delivery time, and lower costs. Standard cabinets equipped with different cards can meet the needs of different projects.
