Abstracts: Programmable logic control (PLC) is the most common automation controller that being used in industry. It is universally applied for factory automation, process control and manufacturing systems. The system is originated from the creation of computerized versions of relay control systems which is used to control machines. There are several types or models PLC used. Ladder logic is a program method which is used to allow the sequences of logical actions to be set up, inter-linked and timed. The program will be developing to control positioning axis and functioning switch and buttoning X-Y Plotter. Ladder diagram (LD) and function block diagram (FBD) are chosen as program languages. The appropriate instruction control programming of X-Y Plotter will be recommended as result, then several suggestion will be recommend from the observation and analysis program developed closely to the project report.
