Abstract

PURPOSE:To perform the stand-by operation of duplicated heat and the single mode operation simultaneously, by providing an interface circuit between the duplicated processing device and the trunk group consisting of a duplicated stand-by trunk and a single mode trunk. CONSTITUTION:Duplicated control interface circuits 34 and 35 are provided between the trunk group consisting of duplicated stand-by trunk 24 and single mode trunk 12 and the processing device which issues commands to this trunk group by the name code. Interface circuits 34 and 35 are tied up with duplicated stand-by trunk 24 to make the duplex constitution. Single mode trunk 12 has bus selecting circuit 36 and is connected to duplicated stand-by trunk 24 and answer returning circuit 32 of interface circuit 34.
