The paper presents different types of controlling and monitoring an industrial process through web interface, depending on the connection types made by PLC or HMI used in the process. We can control the industrial processes through HMI interface directly on the web or phone if we use a Weintek HMI in connection with a SIEMENS PLC for manipulating The possibility to control the SIEMENS PLC S7-1200 is also given by an internal Web server which requires to create an HTML interface and different levels of security for users. Web interfaces are more necessary in controlling and monitoring different processes for future development in IoT structure.
