Prioritized Startup; Device Replacement Without Programming Device - Siemens SIMATIC ET 200eco PN M12-L System Manual

Prioritized startup

Prioritized startup
Prioritized startup denotes the PROFINETfunctionality for accelerating the startup of IO
devices operated in a PROFINET IO system with RT communication.
The function reduces the time that the correspondingly configured IO devices require to
return to the cyclic user data exchange in the following cases:
• After the supply voltage has returned
• After station recovery
• After IO Devices have been activated
The prioritized startup function is not supported for the I/O devices ET200ecoPN M12-L in a
PROFINET IO system with IRT communication as of FW V1.1.0.

Device replacement without programming device

Requirement
A topology must be created in the project.
Device replacement without programming device
IO devices with this function can be easily replaced:
• The device name does not have to be assigned with the programming device.
The replaced IO device receives the device name from the IO controller, no longer from the
programming device. For this purpose, the IO controller uses the configured topology and
the neighborhood relationships determined by the IO devices. The configured target topology
must match with the actual topology.
Before you use them further, reset IO devices that were already in operation to factory
settings.
