Change verification preferences for Logix Designer

Use the
Verification
 tab on the
Workstation Options
 dialog to configure verification preferences. All verification alerts are reported to the
Errors
 tab of the
Output
 window, from which you can navigate directly to the item that caused the warning.
To change verification preferences
  1. Select
    Tools
     >
    Options
     to open the
    Workstation Options
     dialog.
  2. Select the
    Verification
     category.
  3. To enable alerts for routines that are unreached, select
    Enable Detection of Unreached Routines
    .
    • To enable alerts for any unreached routine in the project, select
      All Routines
      .
    • To enable alerts for scheduled routines only, select
      Scheduled Routines Only
      . The alerts are reported to the
      Errors
      tab of the
      Output
      window.
  4. To receive warnings for problems in ladder and structured text routines:
    • Select
      Enable Duplicate Destructive Bit Detection
       for warnings when a bit referenced by an OTE, ONS, OSF, or OSR instruction is destructively referenced elsewhere in the controller.
      TIP:
      Duplicate Destructive Bit Detection (DDBD) occurs on download, whenever you verify the controller, a program, a routine, a rung, or whenever you accept pending edits. The duplicate destructive bits are detected only within the object being verified or downloaded.
      This detection ignores type-less or unverified references, such as rungs, OREFs, or ST lines, and tags.
      When this check box is cleared, all new lines start in column 1 of the structured text routine window view.
    • Select
      Enable Duplicate AOI Backing Tag Reference Detection
       to be notified when a program contains a configuration that can cause AOI interference and overly long Prescan operations.
    • Select
      Enable TND Instruction Detection
       to be notified when a program contains:
      • a possible residual edit operation, and
      • the potential for a major non-recoverable fault (MNRF) due to parameter starvation if a JSR instruction is configured to wait for return arguments.
  5. Under the
    Ladder Routine Verification
     heading, select conditions to detect:
    • To receive a warning whenever a shorted branch is detected on a rung, select
      Enable Shorted Branch Detection
      .
    • To detect rung-condition-out false
      conditions, select
      Enable AFI Instruction Detection
      .
  6. Select
    OK
     to close the
    Workstation Options
     dialog box.
