我正在寻找避免if语句并创建更好的代码的方法，因为我必须在多个PLC中编写它，我认为这是浪费时间，但是我无法弄清楚如何制作代码块，可以做到相同但长度的一小部分。我对PLC编程和一般编码非常陌生。
这里是主要的if语句：
hibak:=0;
If HMI_C1_Defect_Alarm1=1 then
hibak:=10;
elsif HMI_C1_Defect_Alarm2=1 then
hibak:=11;
elsif HMI_C1_Defect_Alarm3=1 then
hibak:=12;
elsif HMI_C1_Defect_Alarm4=1 then
hibak:=13;
elsif HMI_C1_Defect_Alarm6=1 then
hibak:=14;
elsif HMI_C1_Defect_Alarm7=1 then
hibak:=15;
elsif HMI_C1_Defect_Alarm8=1 then
hibak:=16;
elsif HMI_C1_Defect_Alarm9=1 then
hibak:=17;
elsif HMI_C1_Defect_Alarm10=1 then
hibak:=18;
elsif HMI_C1_Defect_Alarm11=1 then
hibak:=19;
elsif HMI_C1_Defect_Alarm12=1 then
hibak:=20;
elsif HMI_C1_Defect_Alarm13=1 then
hibak:=21;
elsif HMI_C1_Defect_Alarm14=1 then
hibak:=22;

我会尽力而为。预先非常感谢！
不幸的是，这是一段脱离上下文的代码。有很多方法可以提高代码质量，一种方法是调整软件体系结构，从而避免这种未经改进的编码风格。
