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、耐用和易接受将获得提高，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，如实用强、耐用强，以及模块。”
欧姆龙的PLC+变频器
欧姆龙推出的其款AC变频器3G3MV，可用于运动控制生产线。适用于小型的电动机控制（0.1到7.5 kW）。它允许用户选择无传感矢量控制，能在低速提供高扭矩，在输出频率为1 Hz时也能保证150%的扭矩。还具有I/O和通信功能。
在去年11月份，它增加了另一项功能，它可有些不寻常，欧姆龙增加了即插用的PLC模块，不只是一个附件，是一个完整的PLC，相当于欧姆龙的标准CPM2C-S PLC。使用双口RAM、PLC直接与变频器的I/O、数据和参数相连。PLC具有自己的I/O，能直接向变频器提供数据：编码输入、中断输出，以及数字式、脉冲式和PWM输出。
欧姆龙认为，这种结合为网络或产品提供了理想的控制方案，能满足在位置和顺序方面的控制要求，也适用于制造业的多步骤包装生产线和智能输送线等。
