Types of available control systems:

1-Microprocessors that are mainly used in small or medium projects with limited variables, and in HATCO are selected from different types of valid and well-known microcontrollers from AC3 series, Logika control, SIEMENS LOGO. This series of controllers, while being cost-effective and easier to operate, have the ability to connect to upstream control systems such as PLC and data transfer to them, as well as DCS system.
