1-1 CPM1 Features and Functions
1-1-1 CPM1 Features
One-piece Construction The CPM1 is a one-piece PC with10, 20, or 30 I/O terminals built into the CPU
Unit.
CPM1-10CDR-
j
(10 I/O Terminals)
CPM1-20CDR-
j
(20 I/O Terminals)
CPM1-30CDR-
j
(30 I/O Terminals)
CPM1-30CDR-
j
-V1 (30 I/O Terminals) (Available soon)
Extra I/O Capacity An Expansion I/O Unit can be connected to the CPU Unit to add an extra 20 I/O
points.
By using the CPM1-30CDR-A-V1 (Available soon) or CPM1-30CDR-D-V1
(Available soon), I/O expansion up to 90 points is possible.
Input Filter Function The CPM1 is equipped with a filter function to prevent incorrect operation
caused by chatter or noise in the input signal. The user can select an input time
constant of 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, 32 ms, 64 ms, or 128 ms.
Low-maintenance Design Flash memory provides memory backup without a battery.
Conforms to EC Directives The CPM1 PCs conform to EC directives (EMC and low-voltage directives), so
they can be incorporated in equipment destined for the EC. Contact your
OMRON representative for more details.
Input Interrupts The CPM1-10CDR-
j
PCs can handle 2 interrupt inputs; the CPM1-20CDR-
j
and CPM1-30CDR-
j
(CPM1-30CDR-
j
-V1 (Available soon)) PCs can handle
4 interrupt inputs. In addition to normal input interrupts, the CPM1 has a counter
mode that counts high-speed input signals and triggers interrupts at fixed count
multiples.
Quick-response Inputs Quick-response inputs can detect input signals with a pulse width as short as
0.2 ms regardless of their timing during the PC cycle. Quick-response inputs
and interrupt inputs use the same input terminals.
Interval Timer CPM1 PCs have a high-speed interval timer which can be set from 0.5 ms to
319968 ms. The timer can be set to trigger a single interrupt (one-shot mode) or
repeat scheduled interrupts (scheduled interrupt mode).
