Replacement scenario of an IM 155-6 PN HS or of a BusAdapter
In a replacement scenario, any IO device or BusAdapter in operation must be reset to its
delivery state via "Reset to factory settings" (see the system manual ET 200SP distributed
I/O system (http://support.automation.siemens.com/WW/view/en/58649293)).
Media redundancy (MRP)
Function for safeguarding communication and system availability. A ring topology ensures
that an alternative communication path is made available if a transmission route fails.

Shared device
IO device which makes its data available to multiple IO controllers.
The interface module supports shared device at submodule level.
Notes on configuring:
● Always load hardware changes to all affected IO controllers.
● Set the same send clocks in the projects.
● Limit the I/O data including user data qualifier to 360 bytes per IO controller.
● Use the same station name and the same IP address for each shared configuration.
● Assign each module or submodule to only one IO controller.
● In the case of an incorrect configuration, you may need to perform a power OFF/ON on
the interface module.
