For programming a flash PROM in a PROM programmer, you need a 1747–M15
Adapter Socket in addition to the PROM.
!
When you write-protect the Flash EPROM, it cannot be burned again. Write-
protecting the EPROM makes the burned program permanent in the EPROM, and
the EPROM 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 flash
EPROM.
Burning EEPROMs (Online Only)
If you have an EEPROM installed in your SLC 500 controller, you may configure your
hardware to use it for program backup, allowing the EEPROM to automatically reload
your project files if the SLC 500 memory is accidentally lost. The processor must be in
the Program mode to burn an EEPROM.
You can burn a program into an EEPROM memory module using a processor that is
different from the one used to run the program. When burning EEPROMs, keep the
following conditions in mind:
•
A SLC 5/03 processor can burn an EEPROM for another SLC 5/03; the SLC 5/04
processor can burn an EEPROM for another SLC 5/04.
•
A SLC 5/02 processor can only burn an EEPROM for another SLC 5/02 processor.
•
Fixed and SLC 5/01 1K processors can burn an EEPROM for a SLC 5/01 4K
processor as long as the program does not exceed 1K.
•
Any fixed or SLC 5/01 processor can burn an EEPROM for any other fixed or
SLC 5/01 processor as long as the program does not exceed 1K.
•
The I/O and chassis configuration of the burning processor does not have to match
the I/O configuration of the program being burned.
•
You do not have to enter the Run mode when burning an EEPROM. If the run
mode is entered and the chassis or I/O configuration does not match, a major fault
will occur. If you burn an EEPROM while in the fault mode, the fault will also be
saved in the EEPROM.
The following table summarizes the above conditions as to the type of processor you
can use to burn EEPROMs for other processors.
