IRT communication with X-200
IRT - Isochronous Real Time
With STEP 7 as of V5.4, you can configure PROFINET devices that support data exchange
using IRT. To achieve the best possible synchronization and performance, IRT frames are
transferred deterministically via planned communication paths in a specified order.
Note
No port mirroring in IRT mode
Disable the function "Port Mirroring" in SCALANCE X
-200IRT devices if you want to operate
the device in IRT mode. IRT mode is not possible when the mirroring function is
enabled.
