    • Vis
      . Select the check boxes in this column to determine which parameters are visible on a function block instruction. This setting only affects instructions in the function block diagram editor.
      If the parameter is wired to another parameter, the check box is selected and cannot be cleared. The parameter must be visible on the block.
    • Value
      . Displays the current value of the parameter. Values in this column are displayed according to the display style of the data type of the block tag.

    Value
    columns to factory default values, select
    Insert factory defaults
