一种基于通信协议的周期性数据通信方法
By introducing slave-level periodic data acquisition commands and master-level data writing commands into the MODBUS TCP protocol, and combining variable transmission and heartbeat keep-alive strategies, periodic data communication was optimized, solving the problem of repetitive data transmission during communication, thereby reducing network transmission load and improving data transmission performance.

AI Technical Summary
In the communication process based on the MODBUS TCP protocol, the periodic communication data transmission is cumbersome and consumes communication resources. Furthermore, the existing communication methods between the master station and the slave station have failed to effectively reduce repetitive data transmission, resulting in excessive network transmission load.
A periodic data communication method based on a communication protocol is adopted. By constructing a slave station periodic data acquisition command and a master station data writing command, combined with variable transmission and heartbeat keep-alive strategies, repetitive data transmission is reduced and the communication process is optimized.
The one-time issuance of periodic data read commands reduces repetitive communication between the master and slave stations, lowers network transmission load, improves data transmission performance, and meets the real-time data communication requirements of industrial control networks.
