Yes; Requirement: IRT and isochronous mode
– IRT
Yes
– MRP
Yes; as MRP redundancy manager and/or MRP
client; max. number of devices in the ring: 50
– MRPD
Yes; Requirement: IRT
– PROFIenergy
Yes
– Prioritized startup
Yes; Max. 32 PROFINET devices
– Number of connectable IO Devices,
max.
256; In total, up to 1 000 distributed I/O devices
can be connected via AS-i, PROFIBUS or
– Of which IO devices with IRT, max.
64
– Number of connectable IO Devices for
RT, max.
256
– of which in line, max.
256
– Number of IO Devices that can be sim-
ultaneously activated/deactivated, max.
8; in total across all interfaces
– Number of IO Devices per tool, max.
8
– Updating times
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
– for send cycle of 250 µs
250 μs to 4 ms; Note: In the case of IRT with
isochronous mode, the minimum update time of
500 µs of the isochronous OB is decisive
– 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)
– 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
