Due to low costs, PLC controllers are used not only in technological processes but also in everyday life. The article presents the possibility of using a PLC controller to control the operation of a sliding gate. For this purpose, a design was created and a sliding gate model made controlled with a Siemens S7-1200 PLC controller. This model is used to develop various gate control algorithms, especially for appropriate gate protection against crushing or uncontrolled closing. In addition, this model is connected via the Internet to a stand equipped with the SCADA application. The iFix 5.8 PL application was used to visualise the operation of the door, which, by means of a communication driver, allows the elevator operation to be controlled remotely. In addition, elements are shown in a graphic way, whereby it is possible to assess the position of the gate.
