 Example
In the above example, the status of the input terminals X(02) to X(05) is captured and output to the output terminals Y(00) to Y(03).
var  Xw
Command Description Argument
Assigns the status of the input terminal variable
to <variable> in units of words.
Variable: any variable
Format
Flowchart method Text language method

<variable> :  Xw
Note The input terminal variable is a variable that detects the status of the inverter's input terminal.
The following settings are required. The numerical order of input terminal variables follows the
numerical order of the set general-input numbers.
Set the Multi-function Input S1 to S7 Selection (C001 to C007) to 49 to 60 (MI1 to MI12: General-purpose input).
When the data is assigned in units of words, zero is read out for the upper byte data and unset input terminal variables.
<Assignment example>
X(00)  MI1 (function No. 49) to Xw  1 (bit 0)
X(01)  MI2 (function No. 50) to Xw  2 (bit 1)
X(02)  MI3 (function No. 51) to Xw  4 (bit 2)
X(03)  MI4 (function No. 52) to Xw  8 (bit 3)
X(04)  MI5 (function No. 53) to Xw  16 (bit 4)
X(05)  MI6 (function No. 54) to Xw  32 (bit 5)
X(06)  MI7 (function No. 55) to Xw  64 (bit 6)
X(07)  MI8 (function No. 56) to Xw  128 (bit 7)
X(08)  MI9 (function No. 57) to Xw  256 (bit 8) (only if expanded I/O for LX is used)
X(09)  MI10 (function No. 58) to Xw  512 (bit 9) (only if expanded I/O for LX is used)
X(10)  MI11 (function No. 59) to Xw  1024 (bit 10) (only if expanded I/O for LX is used)
X(11)  MI12 (function No. 60) to Xw  2048 (bit 11) (only if expanded I/O for LX is used)

Block number Operation
1 Assigns the value of Xw (value of input terminal) to U(00).
2 Divides the value of U(00) by 4 (2-bit right shift) to assign X(02) to bit 0.
3
Performs a logical AND operation on U(00) and 15 (binary: 00001111) and changes the bits higher than X(06) to zero.
4 Assigns U(00) to Yw.
5 Jumps to the block 1: loop_ unconditionally.
