2.2.3 INTERNAL STATUS
On the Internal Status, the system shows all the internal digital flags (inputs, pickups, alarms, etc.). The available
signals in the internal status are grouped in 10 groups of 16 signals each. The last group is the ANDs group; these 16
AND gates may be used by the user to design logic circuits using GE_INTRO software. The inputs to an AND gate
may be internal flags or the output of other AND gate.
