PFI是一个ABBSymphonyDCS控制系统为保护运行设备不被损坏而设置的使控制模件中断运行的保护信号,在实际运行中,由于电源监视模块本身故障引起控制模件停止运行的故障时有发生,因而ABB公司为此发函取消了该保护信号。然而在取消了电源PFI信号后,控制模件的PFI信号要是连接不当,也会使控制模件发生意想不到的故障。经过实验室的大量试验,还原了几个案例中当时的故障现象,本文再对ABBSymphonyDCS系统的电源PFI信号进行了详细地分析,让大家对ABBDCS系统的电源PFI信号有一个新的认识,正确连接PFI信号尤为重要。
PFI是一箇ABBSymphonyDCS控製繫統為保護運行設備不被損壞而設置的使控製模件中斷運行的保護信號,在實際運行中,由于電源鑑視模塊本身故障引起控製模件停止運行的故障時有髮生,因而ABB公司為此髮函取消瞭該保護信號。然而在取消瞭電源PFI信號後,控製模件的PFI信號要是連接不噹,也會使控製模件髮生意想不到的故障。經過實驗室的大量試驗,還原瞭幾箇案例中噹時的故障現象,本文再對ABBSymphonyDCS繫統的電源PFI信號進行瞭詳細地分析,讓大傢對ABBDCS繫統的電源PFI信號有一箇新的認識,正確連接PFI信號尤為重要。

PFI is a protection signal which ABB Symphony DCS control system set to interrupt the operation of the control module to protect the operation of the equipment from being damaged. In the actual operation, because of the fault caused by power monitor module itself sometimes stops the running of control module, ABB company sent a letter to cancel this protection signal. However, if the PFI signal of control module connetted inproper, the cancellation of the PFI signal of power may cause unexpect fault. Through a lot of tests in laboratory, the phenomenon of fault in several cases were restored.This paper will analyse in detail to let everybody have a new understanding of the power of PFI signal of ABB Symphony DCS and the importance of connect PFI signal correctly.
