Prioritized Startup; Device Replacement Without Programming Device - Siemens SIMATIC Distributed I/O ET 200eco PN Operating Instructions Manual

NOTE
Using redundant Sync-Master
When using redundant Sync-Masters, a short-term failure of the 6ES7148‑6JD00‑0AB0 IO-
Link Master can occur during the switching of the Sync-Master.

Prioritized startup

Prioritized startup
Prioritized startup denotes PROFINET functionality for accelerating the startup of IO Devices
for RT and IRT communication within a PROFINET IO system.
The function reduces the time that the correspondingly configured IO Devices require to
recover the cyclic exchange of user data in the following situations:
• After power has returned
• After station recovery
• After activation of IO Devices

Device replacement without programming device

Device replacement without programming device
IO Devices having this function can be replaced easily:
• The device name does not have to be assigned using the programming device.
Instead of the programming device, the IO Controller now assigns the device name to the
replacement IO Device. The IO Controller uses the configured topology and the correlations
derived from the IO Devices. The configured target topology must agree with the actual
topology.
IO Devices that have already been in operation must be reset to factory settings before before
being put back into operation.
