Use of PLC and PIC for realization of intelligent family house

The article deals with usage of PLC (Programmable Logic Controller) and PIC (Peripheral Interface Controller) for realization of intelligent family house model. The aim was to design intelligent family house model with help of microelectronic components and compare advantages and disadvantages of PLC Simatic 314C-2DP and PIC 16F873A in this branch. In this thesis were made for example modules serving for temperature control, DC motor control, lights control or modules for security system. Data transfer between PIC and PC is realized by serial communication and between PLC and PC is OPC (OLE for Process Control) communication. Everything is controlled and monitored from SCADA/HMI system called Control Web 6. Application is accessible via Internet browser in local network. The view of application is adapted to viewing through mobile phone.
