5 Message format of real-time data and commands
5.1 Data message format classification
The data message includes four types. data frame, command frame, information frame and response frame.
Data frame is used for terminal equipment or subsystem (slave station) to transmit real-time data to intelligent factory centralized monitoring system (master station); command frame is used for
The transmission centralized monitoring master station issues control commands and control parameters to the terminal equipment or subsystem; the information frame describes the slave station quantity in ASCII code
Test configuration information; the response frame responds to the received message, replying to the data reception status or command execution status.
All transmitted frames have no delimiters. See Appendix A for a sample data transmission process.
Figure 2 describes the frame structure of the transmission, including the transmission sequence and the description of the fields. The synchronization word is transmitted first, and the check word is transmitted last. Multiple words
When transmitting the words of the section, the most significant byte is transmitted first, and all frames use the same order and format (ASCII character transmission order and representation order).
The order is the same).
The definition of each byte of the transmission frame is shown in Table 1.
