This is the presentation of a thesis developed in the tank pressure control system by using the touch screen works in conjunction with PLCs to be applied in industry. This thesis, which has offered about screen design for contact with Human-Machine Interface (HMI) with GP-Pro EX3.1 and design of programs to control, PLCs (Programmable Logic Controller) with a working principle is that users can enter values for the desired pressure, rain.The touch screen then PLCs will do the processing of measurement values of the sensors (sensor) is compared with the set value on the touch screen, with all the control equipment. At the same time, PLCs will send information back on a touch-screen display in the form of a number that shows the measured values. Which results can be output to control the pressure and have tolerances can be agreed.
