– Number of connectable IO Devices,
max.
512; In total, up to 1 000 distributed I/O devices
can be connected via AS-i, PROFIBUS or
PROFINET
– Of which IO devices with IRT, max.
64
– Number of connectable IO Devices for
RT, max.
512
– of which in line, max.
512
– Number of IO Devices that can be sim-
ultaneously activated/deactivated, max.
8; in total across all interfaces

8
– Updating times
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
Update time for IRT
– for send cycle of 250 µs
250 µs to 4 ms
– for send cycle of 500 µs
500 µs to 8 ms
– for send cycle of 1 ms
1 ms to 16 ms
– for send cycle of 2 ms
2 ms to 32 ms
– for send cycle of 4 ms
4 ms to 64 ms
– With IRT and parameterization of "odd"
send cycles
Update time = set "odd" send clock (any multiple
of 125 µs: 375 µs, 625 µs ... 3 875 µs)
Update time for RT
– for send cycle of 250 µs
250 µs to 128 ms
– for send cycle of 500 µs
500 µs to 256 ms
– for send cycle of 1 ms
1 ms to 512 ms
– for send cycle of 2 ms
2 ms to 512 ms
– for send cycle of 4 ms
4 ms to 512 ms
