HD2-DM-A Operation Modes
Measuring and collecting detailed data is performed within two modes:
•
Segment Focus and
•
Background mode.
Segment Focus must be activated by user for a specific segment. The
Segment Focus is used for exact analysis of system, segment and de-
vice live data with the highest possible update rate. Segment Focus pro-
vides special live monitoring functionalities, e. g. oscilloscope monitor-
ing of the bus signal. If Segment Focus is enabled for a segment
background operations of the other segments may slow down or even
be disabled (current data is frozen). Segment Focus can only be activat-
ed for one segment at a time.
While Segment Focus is disabled, the background mode is always ac-
tive and monitors the status and health of all connected segments. Sys-
tem data is collected with a low update rate. If no fieldbus comunication
is detected at a segment no alarm will be released for signal level data.
