Drive control device and drive control system

摘要

A drive control system has: a plurality of drive control devices; and an upper-level control device to which each of the drive control devices is connected in parallel with each other via a common signal line. The upper-level control device transmits a common information acquirement request signal to each of the drive control devices. Upon receiving the information acquirement request signal, each of the drive control devices determines transmission start timing for a response signal based on transmission sequence information indicating its transmission sequence and a length of the response signal such that the response signal does not temporally overlap with a response signal being transmitted from another drive control device to the upper-level control device. Each of the drive control devices transmits the response signal to the upper-level control device via the signal line at its transmission starting timing. 1 of 8 4-1 Performance 2 Drive control CPU r - -device -3-1 4-4 Drive control device 3-2 Drive control device 3-n 8 of 8 Main control __Performance __ Drive control circuit CPU device 11 2-1 110 1i11 Drive control device 112-2 __Drive control device 1 1 2-5
