CPM2A Features and Functions
Analog I/O Units
Temperature Sensor
Units
CompoBus/S I/O Link
Units
DeviceNet I/O Link Units
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)
CompoBus/S I/O Link Units can be connected to make the CPM2A a Slave De-
vice in a CompoBus/S Network. The I/O Link Unit has 8 input bits (internal) and
8 output bits (internal).
The CompoBus/S Network provides distributed CPU control based on a "PC +
compact PC" configuration, which is an improvement on the earlier distributed
I/O control based on a "PC + remote I/O" configuration. The distributed CPU
control makes equipment modular, so designs can be standardized, special
needs can be addressed, and modules can be replaced easily in the event of a
breakdown.

DeviceNet I/O Link Units can be connected to enable using the CPM2A as a De-
viceNet slave. Up to 32 internal input and 32 internal outputs points are sup-
ported for each Unit, and up to 3 Units can connected. DeviceNet application
allows networks to be constructed including devices from other manufacturers.
