Update times
Minimum value of update time also depends on
the communication allocation setting for
PROFINET IO, the number of IO devices and the
amount of configured user data
Update time with IRT
•
with send clock of 250 µs
250 µs to 4 ms; note: with IRT with isochronous
mode, the minimum update time of 500 µs of the
isochronous OBs is crucial
•
with send clock of 500 µs
500 µs to 8 ms
•
with send clock of 1 ms
1 ms to 16 ms
•
with send clock of 2 ms
2 ms to 32 ms
•
with send clock of 4 ms
4 ms to 64 ms
•
with IRT and "odd" send clock parameter as-
signment
Update time = set "odd" send clock (any multiple
of 125 µs: 375 µs, 625 µs to 3 875 µs)
