Thanks! Now example Master-Slave works fine. But I am confused with reading analog input... What way is ok? 1. --Use ADC component and read adc value adc0_read. --Write this value to holding register with SetHoldingRegister with address 1 and value adc0_read. --Master read the register state (slave ...
