The following attributes are used to define a Change of Value (COV) limit for a point:
!'\QDPLFý&29ýOLPLWýõ<î1ô
This attribute specifies if the system should use an internal algorithm to generate the point
COV limit. Type Y
YY
Y to use the algorithm, otherwise type N
NN
N to specify a numeric value for the
COV limit.
!&29ýOLPLW
This attribute indicates the amount of change, in engineering units, that a point can
experience before a field panel reports the change to other field panels on the BLN.

The following attributes are used when defining analog points:
!)ORDWñý,QWHJHUñý7LPHñý'DWHñý'DWHî7LPH
This attribute identifies the point value format type. There are four different types of point
values for analog points:
x
Float - Floating point values.
x
Integer - Integer values.
x
Time - A floating point value that represents the time of day (for example, 13.5 = 1:30
PM).
x
Date - A floating point value identifying the number of minutes that have passed
since 01/01/1970.
x
Date/Time - A floating point value identifying the number of minutes that have
passed since January 1 at 00:00 in the current year.
!6HQVRUýW\SH
This attribute indicates the type of input that the sensor point receives. The sensor types are:
x
Thermistors (thermo-electric element with electrical resistance that falls with the rise
of temperature).
x
Current (4 to 20 mA).
x
Voltage (0 to 10 Vdc).
x
Pneumatic (3 to 15 psig).
x
L-type sensor (AI sensor terminated on a FLN device).
NOTE:
Sensor type selection for all Trane AI points must be “current.”
