3.编程操作 
常用指令键 
 
 

LD          取                  LDI    取反 

  AND        与                  ANDI  与反 

  OR          或                  ORI    或反 

  ANB      区段与            ORB    区段或 

  OUT      输出                RST      复位 

  SFT        移位                PLS        脉冲 

  NOP        空操作          END      结束 

 
(1) PC RAM 的清除 

        PLC 处于"停止"状态;  编程器处于"PROGRAM"状态. 

        键盘操作顺序如下: 

        [CLEAR]→[STEP]→[0]→[STEP]→[最终步地址]→[DEL] 

        不同型号的 PC 最终步地址表示如下: 

        PC 型号                最终步号 

        F-12R                  477 (八进制数) 

        F-20M                  477 (八进制数) 

        F-40M                  889 (十进制数) 

        F1/F2 系列          999 (十进制数) 

(2)  程序的写入 

        PLC 处于"停止"状态;编程器处于"PROGRAM"状态. 

        键盘操作顺序如下: 

        [CLEAR]→[STEP]→[首步号]→[INSTR]→[指令]→[元件号/常数]→  [WRITE]→ 

                                                                              ↑_______________________________↓ 

        说明: 

        (1)  从第 0 步开始编程时,无需键入首步号. 

        (2) ANB,ORB 等指令输入时,无需键入常数值. 

        (3)  按[WRITE]键前,若需修改指令,先按[INSTR]键,然后写入正确的指令. 

        (4)  按[WRITE]键后,若需修改指令,先按[STEP-]键返回原指令,然后写入正确的指令. 

   

编程举例: 

        要写入的程序如下: 

        ! 

        !      X1        X2                                                      Y 31   

        +---] [---+---]/[---+---------+---------+---------+--(      )-! 

        !              ! 

        ! M160    ! 

        +---] [---+                     

        ! 

        !    X3          T51                                                  T 50   

        +---] [---+---]/[---+---------+---------+---------+--(      )-! 

        !                                                                      !                !
