摘要:针对纸机控制系统复杂、速度同步困难、易出现断纸的现象，本课题依据现场总线通信技术的特点及Profibus-DP主从站具有实现复杂控制系统通信的功能，采用 SFC14“DRD_DAT”和 SFC15“DPWR_DAT”来访问相应控制模块中的输入/输出数据，实现了纸机电气传动数据的高速传输，提高了整个控制网络的数据传输率及整个控制系统的可靠性和抗干扰性，较好地满足了对纸机控制精度和稳定性的要求，提高了纸机的生产效率，为企业取得了良好的经济效益，得到了用户的肯定。

Abstract:According to the characteristics of fieldbus, Profibus-DP master and slave station had the function of realizing complex control system communication. SFC14 “DRD_DAT” and SFC15 “DPWR_DAT” were used to access the input/output data of the corresponding control module, The high speed transmission of paper machine electric drive data improved the data transmission rate of the whole control network and the reliability and anti-jamming of the whole control system, which satisfied the requirements of the control precision and stability of the paper machine and improved the production efficiency of the paper machine, thus enterprises obtained a good economic benefits．
