A Programmable Logic Controller (PLC) is a specialized computing system widely used to control real-time industrial processes and assemblies. The block diagram of a generic PLC is shown in Figure 1.

After more than a decade of articles touting the benefits of PC-based control over programmable controllers and predictions of the PLC's demise, this much is clear: both PCs and PLCs have their place ...

While robot original equipment manufacturers (OEMs) each offer their own tightly integrated controllers, recent developments now enable control by a programmable logic controller, or PLC. For ...

Virtual PLCs run control logic in software instead of hardware. Here's what that means for your manufacturing operation.

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...
