Introduction

This chapter describes basic procedures for operating WindLDR, software required for programming and maintenance of the SmartAXIS Pro/Lite series. Note: SmartAXIS Touch series use WindO/I-NV3 for programming. See the SmartAXIS Touch User’s Manual for instructions for programming and basic operation of WindO/I-NV3 with the Touch series.

Start WindLDR

From the Start menu of Windows, select Programs > Automation Organizer > WindLDR > WindLDR. WindLDR starts and a blank ladder editing screen appears with menus and tool bars shown on top of the screen.

Create Ladder Program

This section describes the procedure for creating a simple ladder program in WindLDR. Note: See "Instructions Reference" on page 4-1 for details on basic and advanced instructions.

Sample User Program

Note: One collection of a group of instructions that control output or advanced instructions is called a rung. WindLDR manages programs in rung units. Function descriptions can be configured as rung comments for individual rungs.

Start WindLDR

From the Start menu of Windows, select Programs > Automation Organizer > WindLDR > WindLDR. WindLDR starts and a blank ladder editing screen appears with menus and tool bars shown on top of the screen.

Create a sample program using WindLDR that performs the following operation: When only input I0 is turned on, output Q0 is turned on. When only input I1 is turned on, output Q1 is turned on. When both inputs I0 and I1 are turned on, output Q2 flashes in 1-sec increments.

Rung No. Input I0 Input I1 Output Operation 1 ON OFF Output Q0 is turned ON. 2 OFF ON Output Q1 is turned ON. 3 ON ON Output Q2 flashes in 1-sec increments.

1: OPERATION BASICS

1-4 FT1A SMARTAXIS U SER’ S MANUAL FT9Y-B

Edit User Program Rung by Rung

Start the user program with the LOD instruction by inserting a NO contact of input I0.

1. From the WindLDR menu bar, select Home > Basic > A (Normally Open). 2. Move the mouse pointer to the first column of the first line where you want to insert a NO contact, and click the left mouse button.

Note: Another method to insert a NO (or NC) contact is to move the mouse pointer where you want to insert the contact, and type A (or B). The Normally Open dialog box appears.

1-6 FT1A SMARTAXIS U SER’ S MANUAL FT9Y-B

When completed, the ladder program looks like below.

The ladder program can be checked to see if it it contains any user program syntax error.

10. From the menu bar, select Home > Convert (above Program) . When the instruction symbols are connected correctly, conversion is completed successfully. If any error is found, the errors are listed on the screen. Then, make corrections as necessary.  Now, save the file with a new name.

Save Project

1. Select the WindLDR application button at the upper-left corner of the WindLDR screen, followed by Save , and type TEST01 in the File Name field. Change the Folder or Drive as necessary.

To insert a new ladder line without creating a new rung, press the down arrow key when the cursor is on the last line or press the right arrow key when the cursor is at the right-most column of the last line.

Simulate Operation

Before downloading the user program, you can simulate the operation on the WindLDR screen without connecting the SmartAXIS. From the WindLDR menu bar, select Online > Simulation. The Simulation screen appears.

To change an input status, place the mouse pointer on the input and right-click the mouse. In the pop-up menu, select Set or Reset to set or reset the input. To quit simulation, from the WindLDR menu bar, select Online > Simulation.

Download Program

You can download the user program from WindLDR running on a computer to the SmartAXIS. User programs can be downloaded to the SmartAXIS from WindLDR using USB or Ethernet. This section describes the procedure from configuring communication settings to downloading a user program to the SmartAXIS via USB. To use USB, the SmartAXIS USB port must be connected to a computer using a USB cable.

Note: In order for WindLDR to communicate with the SmartAXIS via USB, a dedicated USB driver must be installed on the computer. See the “Appendix” of the SmartAXIS Pro/Lite User's Manual for driver installation procedure.

1. From the WindLDR menu bar, select Online > Set Up. 2. The Communication Settings dialog box appears. Click the USB tab and then click OK.  The communication method is now set to USB. Next, download a user program. 3. From the WindLDR menu bar, select Online > Download. The Download dialog box appears, then click OK. The user program is downloaded to the SmartAXIS.

2: LADDER PROGRAM MONITORING ON THE SMARTAXIS

Introduction

SmartAXIS Pro and Touch are equipped with an LCD and capable of monitoring the ladder program in the SmartAXIS. This chapter describes how to use the ladder program monitoring. Notes  For other SmartAXIS Pro functions, refer to the "SmartAXIS Pro/Lite User’s Manual".  For other SmartAXIS Touch functions, refer to the "SmartAXIS Touch User’s Manual".

For the SmartAXIS Touch

Note: The LCD resolution (number of pixels) differs between the SmartAXIS Pro and the SmartAXIS Touch, but the content of the ladder program display screen is the same, excluding the display area for the SmartAXIS Touch operation buttons. This chapter describes the operations using the LCD display on the SmartAXIS Pro. When using the SmartAXIS Touch, read this manual taking into consideration that the operation button display area is omitted.

Button Operations The button operations differ when the button is pressed and released and when the button is pressed and held.

Notes  This chapter describes the button operations for the ladder program monitoring.  For details on SmartAXIS Pro button operations, refer to the "SmartAXIS Pro/Lite User’s Manual".  For details on SmartAXIS Touch button operations, refer to the "SmartAXIS Touch User’s Manual".
