The Smallest PLC in the SYSMAC Fam ily Shows
Just How Far Downsizing Can Go
The 10-point CPU is
approximately the size of a PC Card.
The SYSMAC C Series began developing a
wide range of Programmable Controllers to
meet factory automation needs in 1973.
And now the CPM1A joins the C Series
history as a small PLC that has all the
power of previous small PLCs but requires
far less mounting space. The CPM1A also
provides flexibility in I/O capacity ranging
from 10 to 100 I/O points. The CPM1A can
replace relay control, help distribute I/O,
work as a miniature machine controller or
sensor controller, or fill many other vital
roles in factory automation.

The CPM1A can be easily built into a wide
array of machines or control panels. For
example, you can use the CPM1A to
control a few more I/O points on existing
lines without having to install a new
control panel. Just install the CPM1A in
available space to control only the required
number of I/O. The CPM1A was born to
reduce waste in the factories by effectively
using valuable space.
Flexible Control and Plenty of Power
in the Minimum Body Size
Select Units to Control from 10 to
100 I/O Points
CPUs are available with from 10 to 40 I/O points and, in
combination with Expansion I/O Units, can be used to
control a total of from 10 to 100 points.
Only 30- and 40-point
CPUs support
Expansion
I/O Units. Up to three
Expansion I/O Units
can be connected.

Full Functionality in

User memory: 2,048 words

Timers/Counters: 128
High-speed Execution
LOAD instructions execute at 1.7 µs and MOVE
instructions execute at 16.3 µs for fast program execution.
High-speed scanning is thus possible even with large
programs. Interrupt inputs and quick-response inputs can
be used to handle high-speed pulses that are too fast for
the scan time.

Memory Backup
The user program and memory area data in the CPU Unit are backed up by either one of the following methods.
•Flash Memory:
User program, read-only DM area (DM 6144 to DM 6599), and PC Setup area (DM 6600 to DM 6655).
•Internal Capacitor:
DM areas other than the above, HR area, AR area, and
Counter area.
The capacitor provides backup for a power interruption lasting
20 days at room temperature. If the power is expected to remain
OFF for a period exceeding this data backup period, consider-
ation must be given to the design of the system so that no prob-
lems will occur when the set values become undefined ones. For
further details, refer to CPM1A Operation Manual (W317).

Input Interrupts
There are two input interrupts in the CPM1A 10-point I/O CPU and four in the 20-, 30-, and 40-point I/O CPUs. Input interrupts are
available in two modes.
10-point I/O CPU 20-, 30-, and 40-point I/O CPU
Application Example:
Cutting Metal Sheets to Specified Lengths
The proximity sensor detects the edge of a
metal plate to operate the cutter. Metal sheets
can be cut continuously to the specified
lengths at a high speed.

executed immediately.

There are two quick-response inputs for the CPM1A 10-point I/O CPU and four for the 20-, 30-, and 40-point I/O CPU (shared with the
interrupt inputs). Since an internal buffer is provided, the quick-response input function can even detect signals modified within one
cycle.

Interval Timer Interrupts
The CPM1A has one interval timer. The interval timer shuts down the regular program irrelevant of the point in the cycle once the time
is up, and immediately executes an interrupt processing program. Interval timers are used in the following two modes.
Item One-shot mode Scheduled interrupt mode
Operation An interrupt is executed only once when the time is up. Interrupts are executed repeatedly at fixed periods.

Analog Setting
The CPM1A contains two analog setting controls that can be used for a broad range of analog timer and counter settings. Turning the
setting control stores values of 0 to 200 (BCD data) in the SR area.
Analog setting Storage area Setting value (BCD)
Analog setting 0 SR 250 0000 to 0200
Analog setting 1 SR 251
Application Example:
Tact Operation Control of Conveyor Lines
A conveyor can be stopped temporarily as required for assembly
processes. When the timer function and limit switches are used in a
combination, conveyors can be stopped for a fixed time or can be run
at a constant speed for a fixed distance. Fine adjustment of the stop-
ping time can be easily done by using the analog setting controls.

Communications
Host Link Communications
CPM1A host link communications consist of interactive procedures whereby the CPM1A returns a response to a command sent from
the IBM PC/AT or compatible computer. These communications allow the IBM PC/AT or compatible computer to read and write in the
CPM1A’s I/O Areas and Data Memory Areas as well as in areas containing the status of various settings.

Limitations of the CPM1A 1:1 Link
CPM1A I/O links are limited to 16 words (LR 00 to LR 15). Therefore, use these 16 words (LR 00 to LR 15) on the CQM1 or C200Hj
side when forming 1:1 links with a CQM1 or C200Hj.

High-speed communications can be achieved by providing a direct access through the use of the NT Link between the CPM1A and
