<p>PURPOSE:To attain easy and sure transfer of serial data between microcomputers by applying signal constitution that the level of a start bit is changed over for L and H at every half period of a data bit. CONSTITUTION:The 1st unit 1 executes various signal processing by allowing a microcomputer provided in the inside of the unit 1 to fetch sensor signals S1-Sn fed from various sensors via input ports P11-P1n. Then the result of processing to the said various sensor signals is supplied to various control variables from output ports P21-P2n as control signals C1-Cn. Further, the 2nd unit 2 having a microcomputer executes the similar processing as that of the 1st unit 1. When information required for the 2nd unit 2 is generated in the 1st unit 1, the information is fed to a reception port P40 of the 2nd unit 2 from a transmission port P30 as a serial data.</p> |
