Microcontoller unit. MCU is a type of single-chip microprocessor (computer-on-chip) created for control systems for various electric appliances (telephones, clocks, etc.) and devices, and also to control technological processes. It has minimal memory requirements and simple input/output systems.
Modbus is a serial communication protocol developed by Modicon in 1979. It was designed for establishing master-slave/client-server communication between electronic devices. Nowadays, it is a standard communication protocol in electronics and most widely used means for connecting industrial electronic devices. Its advantages are the fact that it is openly published and royalty-free, and it takes up to several days to implement it.
Micro Processor Unit. MPU is the part of a computer which is responsible for processing commands sent by computer programs and data processing as well.
