What is the difference between motion controller and PLC

In the face of motion control, motion controllers are more specialized than PLC, PLC in addition to controlling the movement, but also other controls, such as musical fountains, walking lights and so on.

Motion Controller: Motion Control (Motion Control) usually refers to the complex conditions of the predetermined control scheme, planning instructions into the desired mechanical movement, the realization of the mechanical movement of the precise position control, speed control, acceleration control, torque or force control.

PLC: PLC, also known as Programmable Logic Controller, is an electronic system of digital computing operations designed specifically for application in industrial environments. It uses a programmable memory to store instructions to perform logical operations, sequential control, timing, counting, and arithmetic operations, and to control various types of mechanical equipment or production processes through digital or analog inputs and outputs.
