CPM2C I/O Specifications
1. CPU Unit Input Specifications
Note: The input time constant can be set to 1, 2, 3, 5, 10, 20, 40, or 80 ms in the PC Setup.
High-speed Counter Inputs
The following CPU Unit input bits can be used as high-speed counter inputs. The maximum count frequency is 5 kHz in differential phase mode
and 20 kHz in the other modes.
Interrupt Inputs
CPM2C PCs have inputs that can be used as interrupt inputs (interrupt input mode or counter mode) and quick-response inputs. The minimum
pulse width for these inputs is 50 s.
In CPU Units with 10 I/O points, inputs IN00003 and IN00004 can be used as interrupt inputs. In CPU Units with 20 or 32 I/O points, inputs IN00003
through IN00006 can be used as interrupt inputs.

CPU Unit Specification
CPU Units with
10 I/O points
(relay outputs)
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.
A CPM2C-CN111, CS1W-CN114, or CS1W-CN118 Connecting Cable, or an Interface Unit (CPM2C-CIF01-V1 or CPM2C-CIF11) is
required to connect to the CPM2C’s communications port.
HR area, AR area, program contents, read/write DM area contents, and counter values are maintained during power interruptions.
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. With CPU Units that are equipped with a clock, the
battery will backup memory for 2 years at 25 C. With CPU Units that are not equipped with a clock, if a battery is not installed, the
internal capacitor will backup memory for 10 days at 25 C. If a battery (optional CPM2C-BAT01 Battery) is installed, it will backup
memory for 5 years at 25 C.
CPU Unit failure (watchdog timer), I/O bus error, battery error, and memory failure
No END instruction, programming errors (checked when operation is started)
