摘要 在通用串口上实现实时性不高的透明数据传送,具有直接读取多个开关量并直接传送的能力。充分利用现有滑触线路实现数据的传送,信号复用电路在接收到数据后还原成开关量信号传回PLC,大大提高了现有线路上的PLC信号的传输能力。 In this paper, not highly real-time transference of transparent data on a general-purpose serial port was realized, and multiple switch signals with direct and immediate transmission capability were read. Transmission of data by existing trolley line was fully used. and returned to the PLC in the signal multiplexing circuit, The received data was reduced to switch signals so the transmission speed of PLC signals on the existing lines was significantly improved.
