!1RUPDOO\ýFORVHGýõ<î1ô
This attribute defines how a digital point will react during a power loss. If a point is normally
closed, the contacts for the DI point are wired to be closed when no energy is applied to the
point. A point that is normally open will have open contacts when no energy is applied to the
point.
!3URRIýõ<î1ô
This attribute defines if a point should be proofed. If the point does have a proof point, then
the system also asks for a proof delay.
!3URRIýGHOD\ýõVHFRQGVô
This attribute defines (in seconds) how much time must pass after a point is commanded,
before the system will check if an alarm condition exists for the point.
!&RXQWýERWKýHGJHVýõ<î1ô
This attribute defines how the system interprets a pulse count. Gain is specified per pulse
edge count. If both edges are counted, each on/off pulse (momentary contact) of the point
produces two pulse counts. If only one edge is counted, each on/off pulse produces one
pulse count. If both pulse edges are counted, gain is doubled.
!*DLQ
This is a number used to convert pulses from a pulse accumulator point into the engineering
units that represent point values. Gain defines the number of engineering units (ranging from
0.001 to 5000.0) represented by each pulse count.

The Metadrop in the System 600 APOGEE is defined as follows:

The Metadrop is Drop 30 on FLN 3.

The Metadrop consists of a group of points known as Metapoints.
A Metapoint for the Open Processor with Trane Driver is always defined with the following

The device address of the BCU
Each Metapoint defines the device address of the BCU and the first of 5 sequential drops on
an FLN where the BCU information is to be mapped. The third drop of the 5 is not used.
