(Note)
While the function keys of @ are displayed in ladder diagram editing, a command of
Q can be executed. For example, entering <A > and [COMAND] on the @ screen
has the same effect as selecting F4 [Adress] on the .a screen. To select a
command of 8 in this way, enter the upper-case letter (not necessarily initial letter)
in the corresponding command name shown on the 8 screen.
Sequence program input
For sequence program input, select [LADDER] from the editing menu. The function key
programmer menu is displayed. When no sequence program has been entered, the screen
displays only the right and left vertical rails of a ladder diagram.
At this stage, program input can be started.
Use the cursor keys to move the cursor to any location in the ladder diagram.
Examples of basic instruction program input and function instruction program input are shown
below.
