User Program Protection
The user program in the
MicroSmart
CPU module can be protected from reading, writing, or both using the Function Area
Settings in
WindLDR
. The read/write protection can be temporarily disabled using a predetermined password.
Upgraded CPU modules with system program version 210 or higher have an option for read protection without a pass-
word, making it possible to inhibit reading completely.
Programming WindLDR
1.
From the
WindLDR
menu bar, select
Configure
>
Function Area Settings
. The Function Area Settings dialog box
appears.
2.
Select the
Others
tab.
3.
Under
Protect User Program
, select required protect modes for
Read Protect
and
Write Protect
in the pull-down
list.
Unprotected:
The user program in the CPU module can be read and written without a password.
Password Protected:
Prevents unauthorized copying or inadver tent replacement of the user program.
The protection can be temporarily disabled using a predetermined password.
Prohibited:
Prevents copying of the user program completely.
This option is available for read protection only and can not be temporarily disabled using a
password. To select this option, use a CPU module with system program ver. 210 or higher
and WindLDR ver 5.31 or higher
•
If the user program is read-protected without using a password, the read protection cannot be tem-
porarily 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.
Warning
•
Before proceeding with the following steps, make sure to note the password, which is needed to
disable the user program protection. If the user program in the
MicroSmart
CPU module is write-
or read/write-protected, the user program cannot be changed without the password.
