Configure X, Y arrays for Function Generator (FGEN) instructions

Use the
X, Y Arrays
 tab on the
Properties
 dialog to configure X and Y arrays for Function Generator (FGEN) instructions.
TIP: To open the X, Y Arrays tab on the Properties dialog:
  • In the editor, insert an FGEN instruction.
    When you add an FGEN instruction in a Function Block Diagram, Logix Designer creates a backing tag for the instruction.
    In the Ladder editor, you create a backing tag for the instruction: Select DotsIcon_v31 to open the
    Properties
     dialog.
  • On the instruction, select the
    Configuration
    icon DotsIcon_v31.
This table describes the parameters on the tab.

Status
Displays read-only status information for blocks containing status bits. If none of the status bits are set, an

Execution Order Number (only applicable to Function Block Diagrams)
Displays the block's execution number if the routine is in a verified state. If the routine is not yet verified, a
Routine not verified
 message displays. Note that this item is read-only.
Never display description in a routine (only applicable to Function Block Diagrams)
Select this check box to prevent the description from appearing in the routine.
