摘要
油淬火—回火碳素弹簧钢丝生产线采用由Citect软件组态的工控机为上位机,和S7-300PLC、变频器组成电气系统,用Profibus-DP接口进行通讯,实时性强,然而其英文操作界面使用不方便。同样的硬件配置,用MPI接口进行通讯,采用国产ForceControl组态软件进行工程设计,主要包括设备连接、页面设计、数据库组态、变量连接、建立配方等功能,完全满足了生产要求,且操作界面通俗易懂,但通讯速度有待提高。给出控制系统的控制框图,用ForceControl组态软件设计时应注意数据库变量的符号和工艺参数的保存方式,调试时应在各种工况条件下分别进行。
The industrial control computer configured by Citect software adopted by the production line of oil-hardened and tempered carbon spring steel wire is host computer. The host computer with S7 -300PLC and transducer make up electric system, which communicates with Profibus - DP interface and has strong practical. But its English operation interface is not convenient. The same hardware configuration which communicates with MPI interface, adopts domestic ForceControl config- uration software to engineering design mainly includes the following functions such as connection, page design, database configuration, variable connection, establishing formula and so on. And it satisfies production requirements. Operation interface is easy to understand, but the communication speed needs to be improved. The control diagram of control system is given out. The symbol of database variable and saving ways of process parameters need to be paid attention when designs with ForceControl configuration software. Debugging should be done under different working conditions respectively.
