Using single-channel switched I/O

What is single-channel switched I/O?
In the single-channel switched configuration, the input/output modules are present singly
(single-channel).
In redundant operation, these can addressed by both subsystems.
In solo operation, the master subsystem can always address all switched I/Os (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 or ET 200iSP.
Single-channel switched I/O configuration at the PROFIBUS DP interface
The system supports single-channel switched I/O configurations containing an ET 200M
distributed I/O module with active backplane bus and a redundant PROFIBUS DP slave
interface module and with the ET 200iSP distributed I/O module.
