[1] Over Write /Insert Mode

It's the mode when the another element was written over on the cell where the instruction (element)

such as A or B contact exist already. The movement is the same on the cell where the element is not

written.

Over write mode : Write over with a new element. (refer to the next paragraph)

Insert mode : Insert the new element. There are two types of inserts : insert left and

insert right. (refer to the page 6-20)

●●

● Change method of mode

There are tow types of changing methods of over write/insert mode

① Double click the [Over write]/[Insert] display part of the status bar.

② Press the [Insert] key.

[2] Modify Circuit

The editing method inside the circuit (1 network) is explained.

(1) Modify instruction (over write and modify)

・You can change the circuit by writing over another instruction on the cell in which an instruction

has been already written.

・Execute over write mode (refer to the previous paragraph)

・Since the CNT instruction uses 2 lines, the line below the CNT instruction will all move down

one line.

・After this, write the second input (reset input) of CNT instruction.

・In the direct input mode, CNT number and "setup value" become the initial values, so that you

need to modify them after the instruction input.

(Example 1)

Modify the A contact to the

horizontal line→ delete A contact

(Example 2)

Modify TMR instruction to

the CNT instruction
