Z版你好，我这段程序是模仿一段程序写的，我也是想查看这段程序具体是如何应用。源程序是这样子的：

IN_PIW_Address          是INT类型    #TMP_PIW_PNT是DW类型

  L     P##IN_PIW_Address           // Load input card address
      T     #TMP_PIW_PNT                // Save analog input address into local pointer
      SRD   24                          // Move the variable area type into the ACCU1 LSB
      L     W#16#80                     // IF variable area type is a PIW
      <I   
      JC    COFF
      TAK  
      L     W#16#81                     // OR variable area type is a IW
      >I   
      JC    COFF                        // THEN the system enables the channel diagnostic
      L     #TMP_PIW_PNT
      L     2                           // Get analog input diagnostic bit address
      /I   
      SRD   3
      LAR1                              // Point to analog input diagnostic bit
      A     DBX [AR1,P#0.0]             //
      =     #TMP_AI_CH_Fault            // Analog input channel fault
