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
