description The invention discloses a serial communication method of a control system, the control system, electronic equipment and a medium. The method comprises the steps that a host end of a control system can send control information and address information to a slave end, the host end receives from the slave end whether slave end data reaches a back pressure signal associated with a preset critical value or not in a data writing stage, and when the back pressure signal associated with the preset critical value is increased, the host end sends the control information and the address information to the slave end; and the host end stops writing data and enters a waiting state, and when a pull-down back pressure signal is associated with the preset critical value, the host end writes data to the slave end, so that the problem that the slave end is fully written can be solved, and the accuracy of data transmission is ensured. 本发明公开了控制系统的串行通信方法和控制系统、电子设备和介质。所述方法包括:控制系统的主机端能够将控制信息和地址信息发送到从机端,由主机端在写数据阶段中从从机端接收从机端数据是否达到预设临界值
