1-1 CPM1A Features and Functions
1-1-1 CPM1A Features
(10 I/O terminals) | (20 I/O terminals) |
(30 I/O terminals) | (40 I/O terminals) |
Extra I/O Capacity | Up to three Expansion I/O Units can be connected to a |
| |
| add an extra 8 or 20 I/O points for each, for a maximum of up to 100 I/O points. |
Input Filter Function | The CPM1A 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. |
Flash memory provides memory backup without a battery. | |
Input Interrupts | The |
| inputs; the |
| |
| can handle 4 interrupt inputs. In addition to normal input interrupts, the CPM1A |
| has a counter mode that counts |
| at fixed count multiples. |
| |
| 0.2 ms regardless of their timing during the PC cycle. |
| and interrupt inputs use the same input terminals. |
Interval Timer | CPM1A PCs have a |
| 319,968 ms. The timer can be set to trigger a single interrupt |
| repeat scheduled interrupts (scheduled interrupt mode). |
| CPM1A PCs have a |
| or up/down mode. The |
| rupts to perform target value control or zone comparison control that isn’t |
| affected by the PC’s cycle time. |
Pulse Output Function | The CPM1A transistor output models have an output function capable of output- |
| ting a pulse of 20 Hz to 2 kHz |
Analog Setting Function | The CPM1A PCs have 2 analog volume controls that can be used to make |
| manual analog settings. |
