Operation Modes
Inputs and outputs which are not used by the counters are available for other tasks.
Table legend: A = input channel A, B = input channel B, Z = output channel Z.
| Operation Mode | Function | Used inputs | Description | Function block |
|---|---|---|---|---|
| 0-1 | No counter | None | This operating mode is selected, if the integrated high-speed counter is not needed. | - |
| 1-1 | Up/down counter (A) | A = Counting input | 1 up/down 32 bit counter on input A (dynamic changes) with set and reset input operation, end value reached indicator, touch/catch value and overflow flag. | CMS_IO_32BIT_CNT |
| 2-1 | Up/down with release input (B) | A = Counting input B = Enable input |
1 up/down 32 bit counter with enable input. Counting is valid when input B is TRUE. Dynamic up/down count possibility, with set and reset input operation, end value reached indicator, touch/catch value and overflow flag. | CMS_IO_32BIT_CNT |
| 3-2 | Up/down counters (A,B) | A = Counting input 0 B = Counting input 1 |
2 up/down 16 bit counter (on rising edge count) functions, with separate up/down, reset operation and overflow flag. | CMS_IO_16BIT_2CNT |
| 4-2 | Up/down (A, B on falling edges) | A = Counting input 0 B = Counting input 1 |
2 up/down 16 bit counter functions (with A on rising edge count and B on falling edge count), With separate up/down, reset operation and overflow flag. | CMS_IO_16BIT_2CNT |
| 5-1 | Up/down dynamic set (B) / rising edge | A = Counting input B = Dynamic set input |
1 up/down 32 bit counter with set and reset input, end value reached indicator, touch/catch value and overflow flag. Additional function to mode 1 is the dynamic set input (B) on rising edge sets START_VALUE. | CMS_IO_32BIT_CNT |
| 6-1 | Up/down dynamic set (B) / falling edge | A = Counting input B = Dynamic set input |
1 up/down 32 bit counter with set and reset input, end value reached indicator, touch/catch value and overflow flag. Additional function to mode 1 is the dynamic set input (B) on falling edge sets START_VALUE. | CMS_IO_32BIT_CNT |
| 7-1 | Reserved | None | - | - |
| 8-1 | Up/down with release (B), 0 cross detection | A = Counting input B = Enable input |
1 up/down 16 bit counter (in range of -32768 to 32767) with enable input and zero crossover detection (CF). Counting is valid when input B is TRUE. With set and reset input operation and touch/catch value. | CMS_IO_16BIT_CNT |
| 9-1 | Reserved | None | - | - |
| 10-1 | Reserved | None | - | - |
| 11-1 | Incremental encoder | A = Trace A of the encoder B = Trace B of the encoder Z = Trace Z of the encoder (mechanical zero) |
