DPT/SE装置主要用于控制两路带有机械和电气联锁的低压断路器，从而 达到自动切换两路供电电源的目的。 一个4位置的控制开关用于设定4种 工作模式；
·自动模式，控制开关置于“自动AUTO”
·正常供电模式，控制开关置于“正常NET”
·应急供电模式，控制开关置于“应急EMER”
·关断模式，控制开关置于“关断OFF”
系统投入运行时，将设定开关置于”运行RUN”位置。 “复位RESET”按钮可 使运行程序恢复到初始状态
a maximum of 100 control stations and 100 operating stations. each control
The station
can support several thousand I/0 points at most, and the scale of the whole system can
be expanded. The hardware of the system control station is encapsulated in an all-metal
shell, which can withstand the most
Harsh industrial environment. The device can be
installed either in a cabinet or on a wall. System complies with all current EMC
standards and is CE marked
Chi.
Industrial” DCS system design purpose: the most
economical engineering investment, the most powerful control function.
Five features of
Industria1″ DCS system:
1. All-round 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.
