Description
Ladder Element
Enter the element to add. The ladder element list advances to the closest match.
If the project uses a controller that does not have a serial port, the
Add Ladder Element
 dialog box does not show the ASCII Serial Port group, which contains the Serial Port instructions (the ASCII String and ASCII Conversion groups and instructions remain). The user-configured tab order is not affected by the removal of the ASCII Serial Port group.

Instruction Help
 pane on and off.
The

 pane is operational for built-in instructions and Add-On Instructions.

 button above the instruction help text navigates to the full instruction help for that instruction.
