3.1 Outline of the Simulator Functions

This section outlines the simulator functions and the precautions

3.1.1 Outline of the functions

The simulator simulates the operations of the ladder diagram crewithout having to connect to the PLC.

The simulator offers the following functions.

Confirms a programs operation status in real-time using the la

registration monitor (timing chart) and monitor all.

Performs simulations using diversified execution methods sucscan, continuous step, one step and one scan.

Enables efficient debugging due to the undo function for execthe reverse direction and execution of continuous step in the r

Provides easy adjustment of preset values, and current value

counters and devices, as well as contact comments.

Sets and resets contacts forcibly.

3.1.2 Restrictions in the simulator

Special utility relays 2002 to 2012 and 2206 are actuated. Othrelays are not actuated.

High-speed counters are not actuated.

The direct clock pulse function is not available.

The positioning control function is not available.

The following restrictions are provided in operations of interru

Data memory is not actuated if external data input is used.

INT CTC* Is not executed.

INT 0000 to INT 0003 Executed in the early portion of a scan.

INT 0003 The timing edge can be changed over wOFF. At this time, the current value of thsigned to the TM30.

3.2.1 Operating procedure for startup and exit

Startup procedure

File Simulator (Ctrl + F2)

The simulator can be started up by opening a ladder program creeditor.Perform the following procedure in the editor.

1. In the editor, set the window of the ladder program to be simuwindow.

2. Select "Simulator" from the "File" menu.

Simulator mode is selected, and the ladder monitor window issame way as in editor mode.

When the same ladder program was previously simulated, theplayed the same way it was when it was last simulated.
