AlarmsString – is a string data that describes the current Alarms situation with the
uCEM module. It is separated from the rest of the data by a semi-colon. AlarmsString
usually is not parsed and used for the presentation purposes only. Example: “1,NOx
Emission Failed. 13 More ...”
Example:
02-05-2002 14:58:53,21.44,1,V,20.09,V,-555.00,V,##.##,0,P,##.##,P,##.##,P,10.37,1,I,
12.45,I,-555.00,I,5.0,3.76,0,1,0;1,NOx Emission Failed. 13 More ...
This string means that the sample was taken February 5 2002 at 2:58PM, O2 values were
all Valid except the 15 Minutes average was not yet calculated, CO process was Off - the
data were not available. NOX data were Invalid and the 15 Minutes average was not yet
calculated. Mega Watts value read from the input was 5.0, Fuel Flow – 3.76
DigInput1(ProcessOn) is set to 0(Off), DigInput2(FlameOn) is set to 1 (On),
DigInput3(Shutdown) is set to 0 (Off)
There were also 13 alarms active, NOx Emission Failed being the most recent one.
