PURPOSE:To simplify the constitution of a transmission part by collecting data at preset timing by a collection control information signal from a preceding transmission part. CONSTITUTION:To one terminal of NAND circuit 1 provided to the data collection controller, collection control information signal P1 from a preceding transmission part is inputted and to the other terminal, collection control information signal P2 is inputted. Further, the output of circuit 1 is applied to one terminal of NOR circuit 2 while transfer timing signal CL from the preceding transmission part is supplied to the other terminal, and its output is connected to counter circuit 3 to supply transfer data D and signal CL to buffer circuit B. In addition, the output of circuit 3 is inputted to decision circuit 6, and a timing signal preset to circuit 6 is applied to gate circuit G gating the output of circuit B; and data D are collected by information signal P1 from the preceding transmission part, so that the constitution of the transmission part at the time of the collection of preceding data D will be simplified. |
