Miscellaneous characteristics

Data link layer options: BACnet IP (Annex J)

Segmentation capability: None

Character sets supported: ANSI X3.4
Basic integration tips:

When integrating, it is important to make sure that the
commands sent are “If Once.” Otherwise it is possible to
set up a system that constantly energizes the solenoids
for the circuit breakers

Set the status read times to be a few minutes for the
entire panelboard unless specifications dictate otherwise.
PRC-E controllers do not support Change Of Value (COV)
subscription; BACnet client must poll for the values of the
objects on the periodic bases

Remember that two states can be read from each circuit
breaker: “Present Value” and “Feedback Value”
 Present Value refers to the last command sent to
the controllable circuit breaker
 Feedback Value refers to the current feedback status
from the
circuit breaker
 By default, many workstations only query the
Present Value
