In my diploma, I described the upgrade of a device for magnetizing permanent magnets. In addition to magnetizing, the device now also allows partial demagnetization, which is used to evaluate the influence of the external magnetic field on permanent magnets. In the upgrade, I used the existing SIEMENS programmable logic controller S7 1214 DC/DC/DC. The movement of the magazine with permanent magnets is carried out with the Ezi - Servo stepper motor, and the measurement of the current position of the magazine is performed with the infrared distance sensor Wenglor. SIEMENS touch screen SIMATIC HMI KTP 400 Basic is used as the human machine interface.
The implementation of the control program in the TIA Portal environment is presented first, then the use of the human machine interface is presented. After installing the components I checked the operation of the control program. Finally, I completed the electrical plan of an upgraded device with EPLAN program.
