Disabling Protection
When the user program is password-protected against read and/or write, the protection can be temporarily disabled using
WindLDR .
If the user program is read-prohibited, the read protection cannot be disabled, thus the user program cannot be read out by
any means. To disable the read protection, download another user program without user program protection.
1. From the WindLDR menu bar, select Online > Monitor. The monitor mode is enabled.
2. From the WindLDR menu bar, select Online > PLC Status. The PLC Status dialog box appears.
3. Under the Protect Status in the PLC Status dialog box, click the Disable
button. The Disable Protect dialog box appears.
4. Enter the password, and click the OK button.
The user program protection is disabled temporarily, and reading is allowed once.
Enabling Protection
When the CPU module is powered up again, the protection designated in the user program takes effect again.
For read or read/write protect, once the user program is uploaded, the protection automatically takes effect again. For write
protect, the protection designated in the newly downloaded user program takes effect.
To change the protection permanently, change the protection settings and download the user program.
