Specifications Section 2-1
Note 1. The DM area, HR area, AR area, and counter values are backed up. If the
backup battery or capacitor is discharged, the contents of these areas will
be lost and the data values will revert to the defaults.
2. The contents of the program area, read-only DM area (DM 6144 to
DM 6599), and PC Setup (DM 6600 to DM 6655) are stored in flash mem-
ory. The contents of these areas will be read from flash memory the next
time the power is turned ON, even if the backup battery or capacitor is dis-
charged.
When data has been changed in any of these areas, write the new values
to flash memory by switching the CPM2C to MONITOR or RUN mode, or
by turning the power OFF and then ON again.
2-1-3 I/O Specifications
CPU Unit Input Specifications
Clock function Shows the year, month, day of the week, day, hour, minute,
and second. (Battery backup) The CPU Units with “C1” in the
model number have a built-in clock.
Not provided on CPU Units
with 32 I/O points.
Communications functions A CPM2C-CN111, CS1W-CN114, or CS1W-CN118 Connecting Cable is required to connect
to the CPM2C’s communications port. The communications port can be used as both a
peripheral and RS-232C port.
Peripheral port:
Supports Host Link, peripheral bus, no-protocol, or Programming Console connections.
RS-232C port:
Supports Host Link, no-protocol, 1:1 Slave Unit Link, 1:1 Master Unit Link, or 1:1 NT Link
connections.
Functions provided by
Expansion Units
Analog I/O Unit: Provides 2 analog inputs and 1 analog output.
Temperature Sensor Unit: Provides up to 8 thermocouple or platinum resistance thermome-
ter inputs.
CompoBus/S I/O Link Unit: Provides 8 inputs and 8 outputs as a CompoBus/S Slave.
Memory protection
(See notes 1 and 2.)
HR area, AR area, program contents, read/write DM area contents, and counter values
maintained during power interruptions.
Memory backup
(See notes 1 and 2.)
Flash memory:
Program, read-only DM area, and PC Setup
Memory backup:
The read/write DM area, HR area, AR area, and counter values are backed up.
CPU Unit with clock (battery): 2-year lifetime at 25°C
CPU Unit without clock (capacitor): 10-day backup at 25°C
CPU Unit without clock (lithium battery): 5-year lifetime at 25°C
Self-diagnostic functions CPU Unit failure (watchdog timer), I/O bus error, battery error, and memory failure
Program checks No END instruction, programming errors (checked when operation is started)
