 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).
Yw  value
Command Description Argument
Outputs data to the output terminal variable in
units of words.
Reflect each bit in corresponding output.
Value: any variable or constant

Flowchart method Text language method

Yw :  <value>
Note The output terminal variable is a variable that controls the status of the inverter's output termi-
nal. The following settings are required. The numerical order of the output terminal variables
follows the numerical order of the set general-output numbers.
MX2: Set the Multi-function Output P1 and P2 Selection (C021 and C022) and the Multi-function Relay
Output (MA, MB) Function Selection (C026) to 44 to 46 (MO1 to MO3: General-purpose output).
RX: Set the Multi-function Output P1 to P5 Selection (C021 to C025) and the Multi-function Relay Out-
put (MA, MB) Function Selection (C026) to 44 to 49 (MO1 to MO6: General-purpose output).
When the data is assigned in units of words, zero is read out for the upper byte data and unset input termi-
nal variables. If there is any setting, the setting is ignored.
<Assignment example>
Yw  1 (bit 0) to Y(00)  MO1 (multi-function No. 44)
Yw  2 (bit 1) to Y(01)  MO2 (multi-function No. 45)
Yw  4 (bit 2) to Y(02)  MO3 (multi-function No. 46)
Yw  8 (bit 3) to Y(03)  MO4 (RX only: multi-function No. 47)
Yw  16 (bit 4) to Y(04)  MO5 (RX only: multi-function No. 48)
Yw  32 (bit 5) to Y(05)  MO6 (RX only: multi-function No. 49)

Flowchart Text
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.
