雷击过电压：当雷电落在输电线路上或者落在输电线路附近，会在输电线路上形成数千伏的瞬态过电压，并沿着线路侵入配电回路而损坏电气设备。 （侵入，反击和感应）
电涌保护器作用：为了保护电气系统和重要的电气设备免遭受雷击过电压的损坏，低压配电系统有必要安装电涌保护器。电涌保护器也被人称为“SPD”． “浪涌抑制器”，“低压避雷器”，“防雷器”，“防雷保安器”等。
保护设备举例：计算机、电视机等贵重家电。电话交换机。消防设备，中央空调，电信局机站设备等等

HART, etc.) and device parameter settings.
● Automatic generation of global data between the process control station and the operator station
According to communication.
For field devices, process control stations and operator stations, a unified global database is used for the entire control system, thereby reducing
cost and time investment in establishing data communication and interactive access.
And ensure the consistency of data throughout the system.
●Provide system-wide unified inspection of user applications, overriding
from process control stations, operator stations to intelligent field devices, including
Including the integrity and consistency check of the user program.
●The programming language strictly complies with the international standard of IEC61131-3, and has
There are high-performance graphics editing functions:
– Function Block Diagram (FBD)
-Ladder Diagram (LD)
– Instruction List (IL)
– Sequence Control Chart (SFC)
. Structured Text (ST)
●Extensive function block library, user-defined function blocks can also be added
Added to it, the macro library and graphic symbols can be customized for the user.
Blocks can create graphics and operator panels.
●Any standard can be integrated by means of GSD file import
PROFIBUS-DP and PA devices, and through user-defined pairing
dialog box to design the configuration window for these devices.
●Profibus field controller can be integrated through FDT/DTM technology
