To modify parameter vales for PPTC instructions
  1. On the instruction in the routine, perform one of these actions:
    • On the Ladder or FBD instruction, select .
    • In the Structured Text editor, right-click the tag name and select
      Configure <tag name>
      .
  2. Open the
    Parameters
     tab.
  3. Set the parameters:
    • Vis
      . Select the check boxes in this column to determine which parameters are visible on the function block. If the parameter is wired to another parameter, the check box is selected, and cannot be cleared because 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 block tag’s data type. If the parameter is wired to, the value column will be read-only, and the value cannot change.
    • Insert instruction defaults
      . Resets the
      Vis
       and
      Value
       columns to the user-stored default values. Use this button to insert instruction defaults saved in registry to this instance of the tag. This button is only enabled when the instruction defaults are available in registry
    • Insert factory defaults
      . Resets the
      Vis
       and
      Value
       columns to factory default values. Use this button to insert factory defaults (initial values) to this instance of the tag.
    • Save instruction defaults
      . Saves currently visible values in the
      Parameters
       tab to the registry.
    • Sort parameters
      . Sort the parameters alphabetically. When this check box is not selected, the default parameter order is applied, with inputs followed by outputs.
  4. View the read-only parameters:
    • Input/Output Row Header
      . An I at the start of a row indicates an input parameter; an O indicates an output parameter.
    • Name
      . The name of the parameter.
    • Type
      . The data type for the parameter.
    • Description
      . The description of the parameter.
