摘　　要：无缝钢管淬火热处理生产线要求具有连续稳定的冷却水供给,以确保钢管质量。调用西门子编程软件Portal中的PID_Compact实现恒压控制,且将程序运算结果通过PROFINET总线传输给变频器,控制水泵的转速,实现变频恒压供水。采用PROFINET IO控制系统,将现场的I/O设备ET200S及变频器设备G120透明的接入PROFINET,实现现场总线系统的无缝集成。The seamless steel pipe quenching heat treatment production line requires a continuous and stable supply of cooling water to ensure the quality of the steel pipe.Call the PID_Compact in Siemens programming software Portal to achieve constant pressure control,and transmit the program calculation results to the frequency converter through the PROFINET bus to control the speed of the water pump and achieve variable frequency constant pressure water supply.Using a PROFINET IO control system,the on-site I/O equipment ET200S and frequency converter equipment G120 are transparently connected to PROFINET,achieving seamless integration of the fieldbus system.
