■ Optimization of Ladder

You can draw freely the ladder diagram in the ladder diagram display area, but when this freely

drawn ladder diagram is modified to be looked better, the ladder is said to be "optimized."

[1] Circuit by the Optimization

If you execute the optimization, the ladder diagram will become the following.

① All contacts will be crammed at upper and at the left side, and unnecessary horizontal lines・

vertical lines will be deleted.

② The position of OUT instruction, TMR /CNT instruction and application instruction will all move to

the position of the corresponding window size which was adjusted to the optimization. Depends

of the size, the horizontal line・vertical line will be either added or deleted. The actual display

position is at the fourth number from the right of the screen, but if there are many AND contacts,

the display position will be set outside the screen.
