EP1258-0502 Microcycle time
The microcycle is the internal cycle of the box in which the inputs are sampled. It depends on the number of activated channels, but not on the MTSF.
A switching edge that arrives at an input channel from outside at any time is recorded during the next microcycle and placed in the buffer. The time inaccuracy for the recording is therefore approx. -x / +0 µs (where x = microcycle time).
Number of activated channels | Microcycle time, typ. | Microcycle time, typ. in compatibility mode |
|---|---|---|
1 | 7 µs | 7 µs |
2 | 10 µs | 9 µs |
4 | 14 µs | 13 µs |
8 | 23 µs | 21 µs |
You can read the current microcycle time in ns from the CoE parameter 0xF900:09 "Sample time".
