Operating procedure
The following figure shows the buttons on the toolbar. The character below each ladder symbol indicates each
function key.
• Use only one-byte characters.
• Check that "Write Mode" is active.
How to input contacts and coils
Users can create ladders with the function keys and tool buttons. To input a contact or coil, specify a position
where a contact or coil is to be input with the cursor and enter a device and label.
Users can switch a normally open contact and normally closed contact with the "/" key.
If an added ladder is in contact with the right rail or is an output device (Y, DY), the ladder is recognized as a
coil. If not, it is recognized as a contact.

program such as the one shown on the left.
