5.8 Device replacement without exchangeable medium

5.8 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.

Note
When you exchange a device, make sure that the PROFINET cable is again inserted into the
correct port, as it is configured in STEP 7.
Otherwise, the system will not run.
Advantages
With the Device replacement without exchangeable medium/PG PROFINET functionality,
you can profit from the following advantages:
● After the replacement of the IO device, it automatically obtains its device name from the
IO controller. You no longer have to assign device names with the PG or exchangeable
medium.
● You can save on the storage medium for the IO device that replaces the removed one.
● Simple device name allocation with series machines that have the same configuration
and set topology. It is no longer necessary to assign device names via exchangeable
medium/PG.
