Depending on the form of protection, one of the following prompts is displayed:
•
Enter list of files to apply memory module
overwrite protection
•
Enter list of files to remove memory module

Memory Module Program Compare Protection
(SLC 5/03 and SLC 5/04 Processors)
If bit S:2/9 is set inside a valid program that is contained in a memory module, you
cannot modify the NVRAM (processor) user program file. This includes online
editing, program downloading, and clear memory commands. Use this feature to
prevent a programming device from altering the NVRAM program from the
program contained in the memory module. If a memory module is installed with
this bit set, and a different NVRAM user program is contained in NVRAM, the
processor does not enter the RUN or REM Run mode. You must transfer the
memory module program to NVRAM in order to enter the RUN or REM Run mode.
To enable this feature, set bit S:2/9 in NVRAM using the data monitor function,
then transfer the program to the memory module.
Memory Module Write Protection
(SLC 5/03 and SLC 5/04 Processors)
Memory module write protection (when selected) allows you to permanently
program the memory module. This option is similar to UVPROM functionality.
Once a memory module is programmed with write protection, you can no longer
write to it using an SLC 5/03 or SLC 5/04 processor.
To enable memory module protection select [F8], Write Protect when transferring
your user program to the memory module. Select [F10], Allow Reuse when
transferring your user program to the memory module to allow future
re-programming. This option is similar to EEPROM functionality.
