The minimum value of the update time also de-
pends on the communication component set for
PROFINET IO, on the number of IO devices, and
on the quantity of configured user data.
250 µs to 4 ms; note: with IRT with isochronous
mode, the minimum update time of 625 µs of the
isochronous OB is crucial
500 µs to 8 ms; note: with IRT with isochronous
mode, the minimum update time of 625 µs of the
isochronous OB is crucial
1 ms to 16 ms
2 ms to 32 ms
4 ms to 64 ms
Update time = set "odd" send clock (any multiple
of 125 µs: 375 µs, 625 µs to 3 875 µs)
