The minimum value of the update time also
depends on communication share set for
PROFINET IO, on the number of IO devices, and
on the quantity of configured user data
125 µs
187.5 µs
250 µs to 4 ms
500 µs to 8 ms
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
