控制从简单的重复循环转移到更多由中断和任务优先级驱动的东西。为此,制造商采用了实时操作系统。对于最终用户来说,它们非常相似,足以让他们熟悉,但从根本上来说,它们发生了转变。这些被称为可编程自动化控制器(PAC)。与此同时,通信变得越来越重要,因此 PAC 配备了通信端口。
的迭代,边缘控制器,将其带到下一个进化阶段。PLC和PC之间的界限越来越细。边缘控制器使这条线几乎模糊不清。但与工业 PC 不同的是,边缘控制器提供专为工业控制设计的功能。
在许多方面,边缘控制器是 PLC/PAC 和工业 PC 的混合体,这意味着它可以在编程和使用方式上提供更灵活的用户体验。它还在传统 PLC 以及工业控制环境中的其他设备之间提供网关。出于这个原因,工业网关也变得很有必要。边缘控制器的潜力在于用单个设备取代 PLC、网关和工业 PC。
切换到边缘控制器
创建工业网络并使其成为物联网的一部分可以通过多种方式实现。边缘控制器有望提供执行此操作所需的许多功能,但这并不是实现它的方法。
对于许多拥有旧系统的制造商来说,将批发转向使用边缘控制器可能是不可行的。边缘控制器制造商了解这一点,并以提供灵活性的方式设计它们。例如,如果 OEM 正在使用新设备扩展其业务,那么可能是转移到边缘控制器的好时机,而他们的其余业务继续在 PLC 上运行。
如果他们已经使用工业 PC 来提供网络连接,那么切换到边缘控制器可能是不必要的中断。但边缘控制器不仅适用于新建安装。工业网关的可用性也在增长,因此可能需要在网关和边缘控制器之间进行选择。

Control moved away from simple, repeating loops to something driven more by interrupts and task priority. To achieve this, manufacturers adopted real-time operation systems. To the end user they were similar enough to be familiar, but fundamentally there was a shift. These became known as programmable automation controllers, (PACs). At the same time, communication was becoming more important, so PACs were equipped with communication ports.
The latest iteration, the edge controller, takes this to the next evolutionary stage. The line between PLC and PC is getting thinner. The edge controller makes that line almost indistinct. But unlike an industrial PC, the edge controller provides features designed specifically for industrial control.
In many ways, an edge controller is a hybrid of the PLC/PAC and an industrial PC, which means it can offer a more flexible user experience in the way it is programmed and used. It also provides a gateway between legacy PLCs, as well as other devices in an industrial control environment. Industrial gateways have also become necessary for this reason. The potential here is for the edge controller to replace the PLC, the gateway, and an industrial PC with a single device.
SWITCHING TO EDGE CONTROLLERS
Creating an industrial network and making it part of the IoT can be achieved in various ways. An edge controller would be expected to provide a lot of the functionality needed to do that, but it isn’t the only way it can be achieved.
For many manufacturers with legacy systems in place, it may not be viable to shift wholesale over to using edge controllers. Manufacturers of edge controllers understand this and have designed them in a way that provides flexibility. For example, if an OEM is expanding its operations with new equipment, it may be a good time to move to an edge controller, while the rest of their operations continue to run on PLCs.
If they already use industrial PCs to provide network connectivity, then switching to an edge controller could be an unnecessary disruption. But edge controllers aren’t only for greenfield installations. The availability of industrial gateways is also growing, so the choice may be between a gateway and edge controller.
