3.3 Ladder Monitor

This section describes the ladder monitor window displayed while the simulator is

running, the scan/step execution procedure, the current/preset value change proce-

dure, etc.

3.3.1 Outline of the ladder monitor

The ladder monitor offers the following functions.

• Executes the scan of the ladder.

• Executes the step of the mnemonic.

• Turns ON/OFF the bit device.

• Changes the current value using the dialog bar.

• Displays all of the registered comments.

• Sets the break condition.

• Sets the scan time.

• Sets the watch dog timer.

3.3.2 Executing scans

Execution of scans is described below.

Outline of the scan execution function

"To execute a scan" means to start a program at the initialization process and run it

through to the end process. This is one scan cycle.

Execution of scans is classified into two types, "execution of continuous scan" and

"execution of one scan". "Execution of continuous scan" is equivalent to the "RUN"

operation in the monitor.

The one-scan time and the watch dog timer can be set. Current values and preset

values can be changed.

Ladder Monitor

If a displayed ladder diagram is closed, select "Ladder Monitor" from the "File" menu

to display it again, or click the

button.

Note 1: This operation is not typically required because the ladder monitor window

is always displayed when the simulator is started up from the editor.

Note 2: Only one ladder monitor window can be opened at a time.
