4.2.9 Diagnostic and Status Indicators
of Fieldline Extension AS-i M8 Devices
Diagnostic indicators
Diagnostic indicators (green/red) indicate whether or not an error is present. In the event of
an error, they indicate the error type and location. A Fieldline Extension AS-i M8 device is
operating correctly if all of the green indicators are on.
Status indicators
Status indicators (yellow) indicate the signal status of the corresponding input/output. If the
yellow status indicators are on, this indicates the signal status "1" of the I/O signal.
Fieldline Extension AS-i M8 devices have two areas for diagnostic and status indicators.
These areas are illustrated in Figure 4-24.
