PURPOSE: A compiler type PLC by using a flash one chip microcontroller capable of converting and storing a relay leader diagram made by a user into a machine language is provided. CONSTITUTION: The compiler type PLC by using a flash one chip microcontroller comprising: a main micom(10) for translating a relay leader diagram into a machine language by a PC(100), including a flash memory for storing the relay leader diagram of the machine language, and reading the relay leader diagram of the machine language stored in the flash memory to control an automation line; an auxiliary micom(20) for receiving a final machine code from the PC(100) and storing it in the flash memory; first and second drivers(30,40) for driving the main and auxiliary micoms(10,20); and interface device(300) for interfacing the auxiliary micom(20) with the PC(100).
