Data that Can be
Stored on a Memory
Cassette
CP1L-EL/EM CPU Units have Memory Cassette functions that enable data in
the CPU Unit to be stored on and read from a special CP1W-ME05M Memory
Cassette. These functions can be used for the following applications.
• Copying data to other CPU Units to produce duplicate devices.
• Backing up data in case the CPU Unit needs to be replaced due to any
malfunction.
• Writing and updating data when existing device versions are upgraded.
Use the following Memory Cassette.

DM initial values (See note.)
The areas for storing various types of data have fixed allocations in the Memory
Cassette, and a single Memory Cassette corresponds to a single CPU Unit.
Therefore it is not possible to simultaneously store multiple items of the same
type of data (e.g., two user programs).
Also, the data can only be read to a CPU Unit. It cannot be directly managed
from a personal computer like files.
The only data that can be stored on a Memory Cassette is the data from a
CPU Unit.
