Memory Cassettes
An optional Memory Cassette can be used to store the user program, PLC setup, and other data in ROM so that vital data will not be lost
in the event of battery expiration or careless programming/monitoring operations.
If the PLC’s settings need to be changed to execute another process, the entire software setup and user program can be changed just by
exchanging the Memory Cassette and rebooting the PLC.

Memory Cassette
Mounted from the front of the CPU and used to store and read the user’s program,
DM (read-only DM and PLC Setup), and expansion instruction information as one block.
It is possible to set the CPU so that data stored in the Memory Cassette (user’s
program, DM, expansion instruction information) is automatically sent to the CPU
(auto-boot) at startup. Transfer and comparison of data between the CPU and Memory
Cassette are possible using AR area control bits.

EPROM Chips
The following EPROM chips (sold separately) are required for EPROM Memory Cassettes.
The chip is mounted in the I/O socket on the Memory Cassette.
