1-1
Section
A CPM2C can be linked directly to another CPM2C, CQM1, CPM1, CPM1A,
CPM2A, SRM1(-V2), or a C200HS or C200HX/HE/HG PC. The 1:1 PC Link al-
lows automatic data link connections. The PC must be connected through the
RS-232C port; it cannot be connected through the Peripheral port.

1-1-2 Overview of CPM2C Functions
Main function
Variations/Details
Interrupts
Interrupt inputs
2 inputs in CPU Units with 10 I/O points, 4 inputs in CPU Units with 20 I/O points
Response time: 0.3 ms
Interval timer interrupts
1 input
Scheduled interrupts
Set value: 0.5 to 319,968 ms
Precision: 0.1 ms
One-shot interrupt
High-speed counters
High-speed counter
1 input see note 1
No interrupt
1 input, see note 1.
Differential phase mode (5 kHz)
Pulse plus direction input mode (20 kHz)
Up/down input mode (20 kHz)
Increment mode (20 kHz)
Count-check interrupt
(An interrupt can be generated when the
count equals the set value or the count
lies within a preset range.)
Interrupt inputs (counter mode)
2 inputs in CPU Units with 10 I/O points,
4 inputs in CPU Units with 20 I/O points
No interrupt
4 inputs in CPU Units with 20 I/O points
Incrementing counter (2 kHz)
Decrementing counter (2 kHz)
Count-up interrupt
Pulse outputs
2 outputs:
Single-phase pulse output without acceleration/deceleration (See note 2.)
10 Hz to 10 kHz
2 outputs:
Variable duty ratio pulse output (See note 2.)
0.1 to 999.9 Hz, duty ratio 0 to 100%
1 output:
Pulse output with trapezoidal acceleration/deceleration (See note 2.)
Pulse plus direction output, up/down pulse output, 10 Hz to 10 kHz
Synchronized pulse control
1 point, see notes 1 and 2.
Input frequency range: 10 to 500 Hz, 20 Hz to 1 kHz, or 300 Hz to 20 kHz
Output frequency range: 10 Hz to 10 kHz
Quick-response input
2 inputs in CPU Units with 10 I/O points, 4 inputs in CPU Units with 20 I/O points
Minimum input signal width: 50
µ
s
Input time constant
Determines the input time constant for all inputs. (Settings: 1, 2, 3, 5, 10, 20, 40, or 80 ms)
Calendar/Clock
Shows the current year, month, day of the week, day of the month, hour, minute, and
second.
Note
1. This input is shared by the high-speed counter and synchronized pulse con-
trol functions.
2. This output is shared by the pulse output and synchronized pulse control
functions. These functions can be used with transistor outputs only.
