System Status
The System Status Viewer aspect follows the basic principles of status presentation
for Safeguard Dual systems, that is, displaying combined status of SCA and SCB in
the Dual Object structure and displaying the individual status of SCA and SCB in
the Single Node Access structure.

The middle position (0) is normal where both SCA and SCB control the
outputs unless isolated for other reasons.
The two other position are marked SCA and SCB. Turning the switch to these
positions sets the related safety controller in local mode. When the safety
controller is in local mode the safety dialog is disabled except for the message
buffer scrolling keys.
