5.9
Device replacement without exchangeable medium
Definition
IO devices which have no slot for exchangeable medium (e.g. ET 200SP, ET 200MP) or IO
devices which support the PROFINET functionality "Device replacement without exchangeable
medium/PG" can be replaced without having an exchangeable medium with saved device
names inserted and without having to assign the device name with the PG. The new IO
device is given a device name by the IO controller and not by the exchangeable medium or
the PG.
To assign the device name, the IO controller uses the configured topology and the
neighborhood relations established from the IO devices.
