How to configure ds3231 RTC module with seven PIC16f72 MCUs

[cmshafi]

I want to connect DS3231 RTC module with seven PIC16f72 MCUs using I2C Multi Master/Slave mode. My pcb already assembled and tested with the MikroC coding with soft_I2C libray. the DS3231 RTC module with single chip of PIC16f72 works well, read and write perfectly. But malfunctioning when I try to connect two or more PICs. so I think it need to configure well, one chip in Master mode and other are slave mode. but I don't know how to set these. please help. how can i set Master mode and Multi slave mode? how can I assign address for each slave PIC chip?
