(1)If a fault occurs and the Controller is in the run mode but is actually operating in the dependent mode, the chassis fault response mode is selected by the last state switch on the chassis backplane.

(2)The I/O chassis is in faulted mode as selected by the last state switch on the chassis backplane.

(3)You must select the operating mode of the remote I/O adapter module as outlined in the publication furnished with the remote I/O scanner/distribution panel, remote I/O scanner-program interface module, or I/O scanner-message handling module. Pay close attention to the disable search mode in the 1771-SD, -SD2.
