4.2.5. Flags
AXON units have 5 internal Flags that can be useful to detect (and take action on) various important
events.
The 5 Flags are:
1P1-Boot Flag.
This flag becomes active whenever the AXON boots up. It is automatically logged
in the System Log, but it can also be used to trigger logging or counting of other events.
1P2-Power On Flag.
This flag becomes active whenever an AXON starts-up from a power-down
state. It can indicate a power failure at the site, and is different from the Boot Flag.
1P3-Sunrise Flag.
This flag becomes active whenever the sun has risen. It obviously requires
that the site’s Latitude and Longitude be entered into the appropriate fields in the Date, Time &
Location screen.
1P4-Connection Flag.
This Flag becomes active after 3 failed login attempts to the AXON. This
event is logged, and can also initiate an alarm to notify site operators about the failed attempts.
1P5-Supply Voltage Flag
. This flag becomes active when the AXON’s power supply voltage falls
below 4.75 Vdc or if it rises above 30.6 Vdc. For detection of other, higher voltages (for example if
an AXON is being powered from a 24 Vdc Bus), a Math function can be used in conjunction with
the 1P5 Value to set different measurement limits.
4.2.6. Math Functions
Math functions are used to perform different operations on various Inputs or IDs (the operands).
The drop-down list below shows the different operations that can be performed on the operands. Note that
the number of operands will automatically adjust from 1 to 4, depending on the nature of the operation
selected. The information window, located just above the operands, shows the actual equation with the
relation of the different parameters.
Besides this particularity, the Math Function settings operate in exactly the same way as the Analog input
settings.
