4.26.5.9.16 Minimum I/O update time
The minimum I/O update time defines how far the bus cycle can be reduced while still allowing an I/O update to
take place in each cycle.
Minimum I/O update time
Without IO-Link (all channels in SIO-Modus)
≥200 µs
With IO-Link
≥400 µs (depends on the minimum IO-Link cycle time of the IO-Link device)
