Device replacement without PG
It is easy to replace IO devices that support this function:
● The device name does not have to be assigned with the PG.
The replaced IO device is assigned the device name by the IO controller. The IO controller
uses the configured topology and the neighboring relationships determined by the IO devices
for this purpose. All involved devices must support the LLDP protocol (Link Layer Discovery
Protocol). The configured target topology must match the actual topology.
IO devices that have been used in another configuration must be reset to the factory settings
before they can be used again (see S7-1500, ET 200MP
(http://support.automation.siemens.com/WW/view/en/59191792) system manual).

Media redundancy
Function for safeguarding communication and system availability. A ring topology ensures
that an alternative communication path is made available if a transmission link fails.

Shared device
IO device that makes its data available to up to two IO controllers.
As of firmware version V2.0, the interface module supports shared device functionality at the
submodule level. A prerequisite for using this function is that the I/O modules also support
this.
If the engineering system performs no plausibility check of the shared device projects, note
the following:
If you reconfigure shared device configurations without the above mentioned plausibility
check, you must recommission the ET 200MP. This means that you have to reload the
projects of all involved IO controllers in the specific CPU after reconfiguration and, if
necessary, switch the interface module POWER OFF/POWER ON.
