Handy built-in functions
make maintenance easier
Memory Cassette
2
• Data, such as programs and initial
memory values, can be stored on
a Memory Cassette (optional) and
copied to other systems.
• The Memory Cassette can also be
used when installing new versions
of application programs.

Analogue Inputs Are Made Simple
1
An analogue control setting and an analogue input
are provided.
Analogue Input
This input has a resolution of 256 steps and is used for an
analogue input set of 0 to 10 V. Each CP1H CPU Unit has one
of these connectors built in. (The built-in analogue I/O for
CP1H-XA CPU Units is separate.) A device, such as a
potentiometer, can be connected to enable direct manual
operation and control from a control panel. The maximum
cable length is 3 metres. A connecting cable (1 m) is included
with the CPU Unit.
7-segment Status Display
3
• The 7-segment Display provides two
display digits.
• In addition to displaying error codes
for errors detected by the PLC, codes
can be displayed on the display from
the ladder program.
• The 7-segment display is useful for
maintenance as well, allowing
problems that arise during system
operation to be grasped without
using any Support Software.
Example display: A memory error occurs in the UM
(error code 80F1, error details 0001).
That's a
memory
error
Analogue setting
The analogue control setting has
a resolution of 256 steps.
When the value is changed it is
displayed (hexadecimal) for three
seconds on the 7-segment display.
Battery-free Operation
4
• The values in the DM Area
(32 Kwords) are saved in the CPU
Unit's built-in flash memory as initial
values, and can be read at startup.
• Battery-free operation is also
possible when saving production
data and machine parameters in the
DM Area, turning OFF the power, and
using the same data again for the
next production run.
Production site
Note:
• A battery is required for the clock function and to retain
the status of HR.
• Area bits and counter values. A battery is provided as
a standard feature with the CPU Unit.
System development
• The user program (ladder program) is stored in built-in
flash memory, so no battery is required to back it up.
