PLC的进一步发展将在2至3年内,而现在已经初露端倪:多处理器和系统平台。”从用户角度出发就意味着,能将功能块放在一块底板上”,PLC和网络专家Hugh Tasker认为,”这些能包括标准PLC技术,但混合了运动控制和过程控制,或是全功能PC的性能,采用局部SCADA或SoftHMI方案技术。”
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
