CPM1A PCs have a high-speed interval timer which can be set from 0.5 ms to
319,968 ms. The timer can be set to trigger a single interrupt (one-shot mode) or
repeat scheduled interrupts (scheduled interrupt mode).
CPM1A PCs have a high-speed counter that can be used in incremental mode
or up/down mode. The high-speed counter can be combined with input inter-
rupts to perform target value control or zone comparison control that isn't
affected by the PC's cycle time.
The CPM1A transistor output models have an output function capable of output-
ting a pulse of 20 Hz to 2 kHz (single-phase output).
The CPM1A PCs have 2 analog volume controls that can be used to make
manual analog settings.
Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs.
Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 ana-
log inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O
Units.
Unit
CPM1A-MAD01 Signal range: 0 to 10 V, 1 to 5 V, or
4 to 20 mA, Resolution of 1/256
The open-circuit detection function
can be used with the 1 to 5 VDC
and 4 to 20 mA settings.
CPM1A-MAD11 Signal range: 0 to V 5, 0 to 10 V, 1
to 5 V, –10 to 10 V, 0 to 20 mA, or 4
to 20 mA, Resolution of 1/6,000
The open-circuit detection function
can be used with the 1 to 5 VDC
and 4 to 20 mA settings.
A Temperature Sensor Unit can be connected to provide up to 6 inputs for tem-
perature input from sensors, such as thermocouples or platinum resistance
thermometers.
Temperature Sensor Unit Functions
Thermocouple input (CPM1A-TS001/002; 2/4 input points):
K: –200° to 1,300°C (–300° to 2,300°F)
0.0° to 500.0°C (0.0° to 900.0°F)
J: –100° to 850°C (–100° to 1,500°F)
0.0° to 400.0°C (0.0° to 750.0°F)
Platinum resistance thermometer input (CPM1A-TS101/102; 2/4 input points):
Pt100: –200.0° to 650.0°C (–300.0° to 1,200.0°F)
JPt100: –200.0° to 650.0°C (–300.0° to 1,200.0°F)
The CPM1A PCs are compatible with the Host Link, which allows communica-
tions with personal computers. The CPM1A using the Host Link can also com-
municate with Programmable Terminal using host link commands.
An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is
used for 1:N communications.
A data link can be created with a data area in another CPM1A, CQM1, CPM1,
SRM1 or C200HS or C200HX/HG/HE PC. An RS-232C Adapter is used to make
the 1:1 connection.
High-speed operations can be achieved by providing a direct access by con-
necting the CPM1A to the OMRON Programmable Terminal through the NT Link
Interface. An RS-232C Adapter is used for this connection.
Up to 3 CompoBus/S I/O Link Units can be connected to make the CPM1A a
Slave Device in a CompoBus/S Network. The I/O Link Unit has 8 input bits (inter-
nal) and 8 output bits (internal).
