Device replacement without removable medium/programming device
IO devices with this function can be replaced in a simple manner:
• A removable medium (such as SIMATIC Micro Memory Card) with the stored device name
is not required.
• The device name does not have to be assigned using the programming device.
The replaced IO Device receives the device name from the IO Controller, not from the
removable medium or 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 setpoint topology must agree with the actual topology.

Changing IO devices during operation (changing partner port)
Functionality of a PROFINET device. If the IO Controller and IO Devices support this
functionality, "changing partner ports" of different devices can be assigned to an IO Device
port by means of configuring, so that communication with each of these changing IO Devices
is possible at a particular time via the IO Device port. However, only the changing device that
is currently being communicated with may be physically connected to the changing port.
This functionality is, for example, a prerequisite for tool change in industrial robots.
In order to realize a tool change as fast as possible, it is also useful to configure a "prioritized
startup" for the devices in the tools together with the setting of a fixed transmission mode
with deactivated autonegotiation and specific cabling rules.
