While the application may be simple, a PLC has lots of built-in capabilities to make things happen behind the scenes, without the user programming needed if a microcontroller is used. PLCs have software watchdogs to keep an eye on the executing program, and hardware watchdogs that monitor I/O modules and devices.

The clue really comes from the name PLC, or “programmable logic controller”. It is the fact that they are programmable that makes them so versatile in their application. PLCs contain a processor, memory to hold their programming and other data and input and output modules. ... A PID Controller is different to a PLC.

While PLCs are the go-to for the Industrial Industry, that doesn't mean that an Arduino can't be useful for the Industrial industry. ... The Arduino is great for small-form solutions that you can build yourself at home, but it can also be utilized on large-scale projects when used to keep track of data and processes.

the CML circuits can operate with lower signal voltage and higher operating frequency at lower supply voltage than CMOS circuits can. However, CML buffers suffer from dissipating more static power than CMOS inverters. ... Due to their superior performance, CML buffers are the best choice for high-speed applications.

Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips. ... Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems.
