Using the menu
This section shows you how to enter/exit the main menu, navigate your way around the
options and how to select an option. The main menu is operated via the four control
panel buttons (MENU, SELECT and the up and down arrows).

Press MENU and hold down for
approximately two seconds (shown
right). You have entered the main
menu when the first option is
displayed.
>> To navigate the main menu
Use a combination of the following:
• Press the up/down arrow buttons
to navigate the options in the
current menu level.
• Press SELECT to move down to the next submenu level or, if you are at the last
submenu level, it selects the current option.
• Press MENU to move up a submenu level without saving any changes or, if you are
at the top level, it exits the main menu.
>> To select an option
Press SELECT.
>> To exit the main menu
Press the MENU button as many times as necessary to take you back up the submenu
levels until you reach the default screen (see “Default screen” on page 21).
The DL351 Modular I/O will exit the main menu automatically after about 20 seconds of
inactivity, that is, if none of the buttons are pressed within that time.

selection, such as an option or parameter.
Flashing option: The bottom line of the display
alternates between the option name and a full line
of dashes (shown right).
Flashing parameter: Only the digits showing
the parameter value will flash.
