Abstract:This paper describes the SCM and PLC briefly; and then explores on the serial communication interface circuit between
SCM and PLC from three aspects which are the interface circuit design, setup of the RS - 232 c serial communication interface
and communication protocol design. From the sending command frame format and the responsing frame format, it proposes the
serial communication process between SCM and PLC, and proposes their application.
