Programmable Logic Controller (PLC) is widely used for the purposes of process control in the industrial world. In its application, the PLC need to be programmed with the appropriate methods and support the appropriate software. One method of programming that is found in almost all support software PLC is Ladder Diagram. But for a complex process, use Diagram Ladder Logic alone would be difficult to solve system design appropriate controls. There are three kinds of programs were created, Ladder Diagram, Function Block Diagram and Instruction List. In the design of automatic water filling machine, PLC is used as an automatic control system. In this case, PLC works by reading an input from sensor and switch which will then be translated and generate the output which are indicator lights, motors, and electric valve. Ladder Diagram programming language is a programming language that is most appropriate to apply on design of an automatic filling machine water with hydropower resources. There fore programming languages Ladder Diagram comparison of the Structured Text Ladder Diagram and Sequential Function Chart Against
