用户对更广泛的实际应用领域和更强的环境适应能力的要求促进了工业以太网协议的发展。啊,数字时代来临了!仅仅过了那么几十年,控制工程师们就开始用数字协议来代替传统的4-20mA模拟控制系统协议了。数字信号控制的优点是毋庸置疑
User requirements for a wider range of practical applications and greater environmental adaptability have facilitated the development of Industrial Ethernet protocols. Ah, the Digital Age is Coming! In just a few decades, control engineers have begun to replace traditional 4-20mA analog control system protocols with digital protocols. The advantages of digital signal control are beyond doubt
