Using Memory Modules (EEPROMs and UVPROMs)
(Not applicable to MicroLogix controllers)
Memory modules provide a non-volatile memory back-up in a convenient modular
form. The modules plug into a socket on the controller.
!
If the PROM is to be “burned” in a processor other than the one it will be running
in, make sure the processors are configured alike; otherwise system errors will
occur.
Available PROMs
You can use an EEPROM (Electronically Erasable Programmable Read Only Memory)
to backup your program. You may also choose to use a UVPROM. A UVPROM is
protected against electrical erasure and is used only for uploading or transferring
processor files from the UVPROM to the processor.
To program a UVPROM you need a PROM programmer and a:
•
1747–M5 adapter socket
•
1747–M3 or 1747–M4 UVPROM
