## Table Content

The LogixNG table lists all of the currently defined LogixNGs. Each row has a standard set of columns.

System Name
  The system name for the LogixNG. LogixNG system names have an IQ prefix normally followed by numbers. For details about the LogixNG system name, see Add a LogixNG. The system name cannot be changed.
User Name
  The user name for the LogixNG. This is a free form field that contains a meaningful name.
Enabled
  A LogixNG can be enabled or disabled. When it is disabled, the related ConditionalNGs will not be active.
Comment
  A free form comment field for the LogixNG
Menu
  The Select combo box is used to select actions for the selected LogixNG. See Select Actions

## Select Actions

The dropdown combo box has 4 actions that can be applied to the current LogixNG row.

Edit
  When Edit is selected, the LogixNG editor will open. This window will contain the ConditionalNGs that have been defined for this LogixNG. See LogixNG Editor for details.
Browse
  The Browse option opens a text window with a representation of the definitions within the LogixNG. See LogixNG Browser for details about the browser.
Copy
  The Copy action is used to create a duplicate of the current LogixNG. Note: This feature is not available yet.
Delete
  The Delete action deletes the current LogixNG, all of its ConditionalNGs and the ConditionalNG content. A confirmation dialog will be displayed.

## Menu Items

Options
  The options menu has two items: Enable All LogixNGs and Disable All LogixNGs. Selecting one of these will perform the action on all the LogixNGs in the table.
Tools
  The tools menu has one item: Open PickList Tables. The PickList was designed for dragging names, such as sensor names, to a text field. Due to the implementation of ConditionalNG edit dialogs, the drag and drop capability does not function. It can still be used as a reference.

## Add a LogixNG

To create a new LogixNG, click on the Add... button. The Add LogixNG window will be displayed.

The system name is required. The system name for a LogixNG always begins with the letters IQ. If the entered name does not start with IQ, it will be automatically added. The typical suffix is a number. If Automatically generate System Name is checked, the system name format will be IQ:AUTO:nnnn. Any other format requires adding a $ (dollar) character between IQ and the suffix.

The user name is optional but recommended. A user name may be any useful text, provided the new user name was not previously assigned to another LogixNG. Once a LogixNG is created, its system name cannot be changed. Its user name may be changed in either the LogixNG Table or the Edit LogixNG window. The user name is usually used to provide a more descriptive name, for example, "Signal 5 Control".

After clicking Create, the LogixNG will be created and the Edit LogixNG window will appear.
