These optional memory modules provide a non–volatile memory back–up in
a convenient modular form. The modules plug into a socket on the
controller.
You can store (save) your program in the EEPROM by inserting it into the
processor and using either the Hand–Held Terminal or Advanced
Programming Software.
Use of the UVPROM provides you with an extra degree of program security
because the user program cannot be altered while it is installed in the
controller. You can program the UVPROM with commercially available
UVPROM programming and erasing equipment. You can use an EEPROM
module as a master, or you can use an archived processor file as the source
by using the APS PROM translator utility.
Adapter sockets are required when inserting memory modules into
commercially available PROM programmer. The memory module fits into
the adapter socket and then into a PROM programmer.
!
ATTENTION: Make sure the adapter is inserted properly or
damage could result.
The following table lists the types of memory modules that are available for
the fixed controller. Also listed are the manufacturer part number for
determining compatibility with an external PROM burner.
