CPM2C-S PCs have two outputs that can produce 10 Hz to 10 kHz pulses
(single-phase outputs).
• When used as single-phase pulse outputs, there can be two outputs with
a frequency range of 10 Hz to 10 kHz with a fixed duty ratio or 0.1 to
999.9 Hz with a variable duty ratio (0 to 100% duty ratio).
• When used as pulse plus direction or up/down pulse outputs, there can
be just one output with a frequency range of 10 Hz to 10 kHz.
The CPU Units have 2 inputs that can be used as interrupt inputs. These
inputs are shared with quick-response inputs and interrupt inputs in counter
mode and have a minimum input signal width of 50 µs and response time of
0.3 ms. When an interrupt input goes ON, the main program is stopped and
the interrupt program is executed.
The CPU Units have 2 inputs that can be used as quick-response inputs to
reliably read inputs with a signal width as short as 50 µs regardless of the
cycle time. These inputs are shared with interrupt inputs and interrupt inputs
in counter mode.
The input time constant for all inputs can be set to 1 ms, 2 ms, 3 ms, 5 ms,
10 ms, 20 ms, 40 ms, or 80 ms. The effects of chattering and external noise
can be reduced by increasing the input time constant.
Up to 3 optional Analog I/O Units can be connected to the CPM2C-S. For
each Analog I/O Unit mounted to the Unit, 2 analog input points and 1 analog
output point are available. By mounting 3 Analog I/O Units, a maximum of 6
analog input points and 3 analog output points can be made available. (By
using a combination of the PID(––) instruction and PWM(––) instruction, time
proportional control is possible.)
• The ranges supported for analog input signals are 0 to 5 V, 0 to 10 V, –10
to 10 V, 0 to 20 mA, and 4 to 20 mA, and the resolution is 1/6000 (full
scale). The averaging function and power interruption detection function
can be used.
• The ranges supported for analog output signals are 1 to 5 V, 0 to 10 V,
–10 to 10 V, 0 to 20 mA, and 4 to 20 mA, and the resolution is 1/6000 (full
scale).
Up to 8 analog inputs and 8 analog outputs can be connected through a Com-
poBus/S Analog I/O Terminal.
Up to 3 optional Temperature Sensor Units can be mounted to the CPM2C-S.
There are 2 models of Temperature Sensor Unit: One for input from a thermo-
couple sensor and one for input from a platinum resistance thermometer sen-
sor. There are 2 input points on each Temperature Sensor Unit.
• Thermocouple inputs (and measurement ranges): K (–200 to 1,300°C), K
(0.0 to 500.0°C), J (-100 to 850°C), and J (0.0 to 400.0°C).
• Platinum resistance thermometer inputs (and measurement ranges):
Pt100 (–200.0 to 650.0°C), JPt100 (–200.0 to 650.0°C).
