3.4.3. Inserting variables

Select the "Insert variable" icon (Figure 2-10) in the program editor window. Then place

the cursor to the left of the function block, making sure that enough space is left so that the

input variable does not overlap the function block, and click on the mouse.

Select the "I62.00 - IN1 - Switch" variable in the variable list

Validate with "OK". The variable appears with its name.

Comment: If the "Cannot overlap graphic symbols" message appears instead of the

variable then restart the manipulation leaving enough space to the left of the block for the

variable insertion

Use the same procedure to insert the internal bit to the left of the function block and below of

the input variable and select the "M00.00 - TEST" internal bit.

Use the same procedure to insert the output variable to the right of the function block and
