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.

While PLCs (programmable logic controllers) are an industry norm, demands for data, memory, and processing power are intensifying. Soon enough, the PLCs may no longer be the go-to industrial computer.

The programmable logic controller is more than 50 years old, but its basic function to manage manufacturing processes is pretty much the same as when it was first conceived. As this week’s Machine ...

Narrow-band low-frequency power-line communications (NB LF PLC) is a hot topic these days. Engineers creating PLC modems must consider which PLC standard (PRIME, G3, S-FSK) will be used and which ...

Trio Motion Technology has launched Motion-PLC, a new class of machine controller that combines motion, robotics, and logic. Motion-PLC provides Trio’s advanced motion control performance with the ...

For applications combining traditional automation, multi-axis coordinated motion control, and a need for data handling, a motion-optimized PLC platform provides an elegant and streamlined solution.

As end-users take advantage of more capable PLCs, they must also consider security. By increasing the overall computing power of PLCs, controller vendors have made room for additional capabilities.
