UNI. You must then use BACnet point
microblocks to access U253 points through
the keypad.

Point Identifiers

A point can be identified in WebCTRL by its
point number and point type; in SuperVision,
a point is identified by its channel number. On
both systems, expander number zero
represents I/O points on the U253.
Point Identifiers in WebCTRL
Enter the point identifiers in Eikon for
WebCTRL before the FB is made or on the FB's
Properties page in WebCTRL. Set the type,
number, and minimum and maximum
present values for each point on the U253.
Select a physical point type from the Point
Type field and enter the number of the input
or output. If needed, enter an expander
number. To scale a linear signal type, enter
the appropriate minimum and maximum
present values on the microblock's dialog
box.
If you are not using a LogiStat in a WebCTRL
system but would like to use the two inputs
that are available on the LogiStat port, assign
an address of 16 for the temperature input
and 17 for the setpoint input.
Channel Numbers in SuperVision
Refer to Table 2 and Table 3 for channel
numbers for each physical point on the U253.
The channel number, offset, and gain for each
point can be entered in Eikon before the
Function Block is made, or on the FB's
Parameter page in SuperVision.

† Use the Point Help feature of SuperVision for Windows v2.0 or later to
determine offset and gain for these types of inputs.
‡ Channel numbers for these inputs are set by the LogiStat microblock and do
not need to be manually entered in SuperVision or Eikon.
‡‡ A1 is 10-second averaged. A2 is not averaged.
