1440-DYN02-01RJ 动态测量模块(DYN)保持与 1440-VST02-01RA 动态模块(XM-120)相同的基本用途和功能。两种模块均用于为汽轮机、燃气轮机、水轮机、电机、压缩机、泵、风机、鼓风机和其它大部分旋转机械提供常用的监测解决方案。
主要的区别是 XM-120 主要是满足独立使用需要，但也提供了一些基于连接的标准，而 DYN 则是专为集成于ControlLogix 环境中而设计的。针对不同应用，XM系统的电源要求可能会有很大区别。 并且除功率(安培)外，还必须考虑诸多问题，例如温度范围、保持时间和过电流保护，以及系统方面的考量因素，例如冗余电源、与 API-670 的兼容性和是否用于危险区域等。 因此此，采用的电源方案是否得当是考量一个系统的关键。本文档旨在为合理地设计和选择 XM系统的电源方案提供帮助以满足这些要求。
nternational 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 have
