Write-protecting the memory module makes the burned program permanent in the
memory module, therefore the memory module cannot be erased or overwritten
using PLC-500 A.I. Make absolutely sure the program is exactly how you want it
before write-protecting the memory module. To change the program you would have
to buy a new memory module.
7. The utility translates the file. The HEX file is stored in the same directory as the
ACH file from which it was generated.
When you exit PLC-500 A.I., the hexadecimal file can be exported or copied to your
PROM programmer using DOS commands or your UVPROM programmer software.
