User Program Protection

You can enable protection for uploading and downloading the user program with WindLDR to help prevent the FC6A Series
MICROSmart user program from being modified, erased, or stolen by a third party.
Protection can be individually configured for uploading and downloading the user program. There are three types of protection
modes, which are detailed as follows:
Mode
Unprotected
Password Protected
Prohibited
For enhanced security, if the entered password does not match the user program password in the FC6A Series MICROSmart, the FC6A
Series MICROSmart will not verify a new password for one second. Therefore, even if the correct password is entered within one second
after a mismatch, that is a mismatch. If the password does not match, wait one second or longer and then enter the password again.
Note: When the user program is password protected, there are restrictions on uploading and downloading the user program using the SD memory
card. For details, see "Download from SD Memory Card" on page 11-27.
Notes:
Before proceeding with the following steps, make sure to note the protect code, which is needed to disable the user program protection. If the

user program in the FC6A Series MICROSmart is write- or read/write-protected, the user program cannot be changed without the protect code.
If the user program is read-protected without using a password, the read protection cannot be temporarily disabled using the password, thus

the user program cannot be read out by any means. To disable the read protection, download another user program without user program
protection.
When the user program is protected, even if you enter the correct password and download the program, if protection is set for the

downloaded user program, the protection will be once again enabled.
If you do not download or upload the user program within 10 seconds of unlocking the protection, the protection will once again be enabled.

Programming WindLDR
From the WindLDR menu bar, select Configuration > Program Protection.

The user program is unprotected.
A password must be entered when downloading or uploading the user program.
The password is six to eight single-width alphanumeric characters, and it must include a minimum of one
number and one character.
One password can be set for one user program.
When applying password protection to both user program uploads and downloads, the same password is used.
The user program cannot be uploaded. Prohibited protection can only be configured for user program
uploads. User program downloads cannot be prohibited.
