Abstract

The invention provides a serial communication configuration and debugging method based on Ethernet communication protocols. The method performs configuration, surveillance, monitoring, debugging and other operations on a lower computer by using the software of an upper computer, users do not have to care about the system architecture of the hardware of a serial communication module, and configuration, monitoring, debugging and other operations on serial information of the lower computer can be realized by simply configuring the upper computer instead of using a hyper terminal and other complex operations to monitor each serial device. Meanwhile, the software communication is based on the Ethernet communication protocols, most communication requirements of PLC communication modules can be satisfied, and the method has good universality.

Description

technical field [0001] The invention belongs to the technical field of self-control software development, and mainly relates to the development of the communication protocol of the PLC communication expansion module, configuration software and serial port information monitoring software. Background technique [0002] Due to its early development, maturity and reliability, serial communication has strong applicability and wide application range. In the PLC system, due to the large number of on-site serial devices or instruments, the PLC needs to expand the serial port; and multiple serial ports communicate at the same time, and the operating communication protocols are also different. It is necessary to support the simultaneous operation of multiple serial port communication protocols. For the monitoring and debugging of serial port information, it is difficult to realize through the serial port communication module, which puts forward very high requirements for on-site debug...
