WindLDR

Welcome to WindLDR!
Thank you for purchasing "WindLDR".
WindLDR is a pure 32-bit application with WYSIWYG (what you see on screen) ladderprogram editing capabilities.
Highlights of WindLDR are as follows.

Compatibility of Ladder input program
WindLDR8.0 can read files created with version 4.0 or later. This compatibility allows you toreuse past assets.

Enhanced help functions
In addition to WindLDR help, you can refer to the functions of the controller on the screen.
You can refer to instructions and the functions of special internal relays and special dataregister on the screen as well.

Flexible display
You can freely change the character size and line thickness of the ladder symbols. Thechanged contents are also effective when printing and sending a ladder diagram by FAX.
A function to fix the number of columns is provided. In the old version of WindLDR, whencreating a horizontally long program, the screen scrolled horizontally. Also, when printing,the program was printed horizontally across multiple pages. By fixing the number ofcolumns, the right end is fixed and all programs can be edited without scrolling horizontally.
A horizontally long program that does not fit in a line is automatically wrapped.

Notes - WindLDR
There are the following notes for using WindLDR. Thank you for your understanding.

Print
When the number of ladder lines exceeds 1500, Print/Print Preview may fail.

New file format
The old versions of WindLDR save the user program depending on the function used inseven types of files as follows,-*.ldr: ladder diagram file*.sym: symbol file*.bmk: bookmarks file*.cus: custom monitor data*.pcv: print settings data*.obu: device data list*.cod: binary data to PLC transferred

WindLDR version 6.0 or later stores the project data in a single file (*.pjw), which contains
all project data.

Compatibility
1) The files created with WindLDR version 6.0 or later cannot be read with earlier versionsof WindLDR.
2) WindLDR version 6.0 or later can read the files created with WindLDR version 4.0 or later.
However, the following files cannot be read.
- Files whose PLC type is not FC5A, FC4A, or OpenNet- Files containing instructions for unsupported PLCs, such as FA Series PLC

Only one project can be opened at a time
Only one project can be opened with WindLDR version 6.0 at a time. To create or open
another project, you have to close the current project.

Current value, Preset value, and Contact of Timers and Counters
WindLDR version 6.0 supports individual device types for current value, preset value, andcontact of Timer and Counter whereas earlier versions of WindLDR have only one device
type for all. You can assign Tag Names and comments to each device.
The table below shows how Timer and Counter are used in WindLDR versions 5.0 and 6.0.
WindLDR Ver.5*

WindLDR Ver.6*

T (Timer)

T (Timer Contact)
TC (Timer Current)
TP (Timer Preset)

C (Counter)

C (Counter Contact)
CC (Counter Current)
CP (Counter Preset)

Example:Example:The symbol T is used for Timer contact,current value, and preset value.

The symbol T is used for the contact, TC is used
for the current value, and TP is used for thepreset value.

When a file created with an earlier version of WindLDR is opened with WindLDR version 6.0,
T (Timer) is converted to T (Timer Contact), TC (Timer Current), and TP (Timer Preset), andC (Counter) is converted to C (Counter Contact), CC (Counter Current), and CP (Counter
Preset) depending on how T and C are used in the program.
