The minimum value of the update time also de-
pends on communication share set for
PROFINET IO, on the number of IO devices, and
on the quantity of configured user data
250 μs to 4 ms; Note: In the case of IRT with
isochronous mode, the minimum update time of
625 µs of the isochronous OB is decisive
500 μs to 8 ms; Note: In the case of IRT with
isochronous mode, the minimum update time of
625 µs of the isochronous OB is decisive
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 ... 3 875 µs)
250 µs to 128 ms
500 µs to 256 ms
1 ms to 512 ms
2 ms to 512 ms
