Note
Failure of downstream stations is possible
Downstream stations on a bus segment can fail when the factory settings are restored on an
interface module.
Note
Behavior of the installed I/O modules during reset to factory settings
The I/O modules of the ET 200SP distributed I/O system assume the unconfigured state
after a reset to factory settings. The interface module does not acquire any input data and
does not output any output data.
