Hello!

What is the difference between controller and microcontroller? (Is there anything like "macrocontroller"?)

Controller is a generic term for a finished product like a PLC, PID, or CNC controller...

Microcontroller usually refers to a CPU chip with on board memory and I/O. It is used as part of a controller.

I have never heard anyone say the word macrocontroller.
