The construction of a PLC simulator for level control

This paper represents the construction of a PLC simulator for the level control of water and the speed control of the water cask. The level and speed processes are automatically operated by the PLC. The simulator system consists of PLC, program loader and control penal. The digital input and output units make the valves of the water cask the On or Off state. The analog input and output units control the level of water and the speed of the water cask. A LD program is used in the control language of PLC.
