那发展方向是什么呢?他认为,对于用户,大的好处在于控制系统结构的简化。”不用再集成很多PLC,将他们连接,然后再运行和维护,现在的许多系统将减少PLC的个数,甚至就采用一个。这可以大大节省安装和维护时间,整个系统的耐用性也更强。
他也推测了未来,”在很长的一段时间,蓝牙技术和无线以太网技术的应用将更为广泛。它将先在小范围内起步,但在可靠性、耐用性和易接受性将获得提高,制造商还将有可能寻求无线技术的应用,也许某天他们连基本的线缆都省去不用了。
贝加莱自动化是控制产品供应商,提供工业PC,但相对于其他PLC制造者,它在PLC领域的时间也颇长。但他们却从来没有纠缠于PC与PLC孰强孰弱的问题,两者在共同发展。而且现在贝加莱看到了发展方向上的一些契机,也许两者的技术能不断融合。
“在过去的几年中,经典可编程逻辑控制器的发展始终向嵌入式PC技术发展,”贝加莱业务经理Anton Meindl认为,”PC技术有其优点–巨大的计算能力、与因特网技术的结合、快速以太网和USB接口,能结合传统的PLC系统的优点,如实用性强、耐用性强,以及模块性。”
