Note
IO redundancy
The term IO redundancy is als
o used for the connection of a redundant I/O to PROFINET IO
If you are using an I/O in a system-redundant configuration, you always use the same
address when addressing the I/O.
Using single-channel switched I/O
What is single-channel switched I/O?
In single-channel switched configuration, there is one of each of the input/output modules.
In redundant operation, these can addressed by both subsystems.
In stand-alone operation, the master subsystem always addresses
(in
contrast to one-sided I/O).
The single-channel switched I/O configuration is recommended for system components
which tolerate the failure of individual modules within the ET 200M, ET 200iSP or ET 200SP
