基于Modbus通信协议的油田RTU调试软件设计与实现摘要:在考察数字化油田建设情况的基础上,研究油田现场无线仪表与RTU通信方式及其各参数的含义,提出了一种新型油田RTU调试软件设计思路。在油田现场,RTU与上位机软件之间的通信方式为串口Modbus或网口Modbus通信,在VS2010开发环境下,用C#编程实现这两种通信协议,调试人员可根据...

Compounds 4 and 5 present the same fragmentation pattern but are characteristic of trimeric and tetrameric molecules, respectively, meaning that they contain more than two residues of acylphloroglucinol and/or syncarpic acid (Figure 5, Supplementary Figures S8 and S9). Similarly to compounds 3, 4...
all of our tungsten alloy bucking bar is made of 90+% W tungsten heavy alloy materials. Tungsten alloy bucking bar is the best choice for riveting, especially in confined spaces. With a suitable bucking bar, your task will be easier and your riveting more precise, meaning less rivets to dr...
