APPENDIX D — BACnet OPTION (cont)
TESTING THE INSTALLATION — To verify that the don-
gle connection is correctly inserted and detected by the equip-
ment, with the controller powered up, go to the PIC 5 Main
Menu  nputs Status and confirm that the BACnet Dongle
status is Yes.
BACnet Settings — BACnet settings are available on
the Main Menu  Configuration Menu  BACnet Config.
The menu requires the Advanced User password for access.
For details, see the Bacnet Config table on page 79.
BACnet Objects — The 19XR PIC 5 contains up to 500
BACnet objects. They can be of ANALOG_VALUE (AV) or
BINARY_VALUE (BV) type. Objects name are built from
CCN table name and CCN point name concatenated in order to
recognize them easily. For a detailed list, see the BACnet
Points table beginning on page 100.
In general, the equipment configuration parameters are
available as Read Only. Set point parameters are available in
Read-Write access.
Compressor status is ASCII-coded. In order to obtain the
status from BACnet, statuses are assigned a BACnet code as
shown in Table A.
Table A — Equipment Status
Alarm states are coded as shown in Table B.
Table B — Alarm States
Modifying the Unit IP Address — Note that chang-
ing IP address from the PIC 5 SETUP menu will require a
manual reboot or power cycle of the PIC 5 controller in order
to re-build the BACnet stack. For detailed instructions, see the
Unit IP Address section on page 52.
BACnet IP Communication Problems — If the
unit does not respond to the building management system, pos-
sible causes include the following:
• The BACnet dongle is not detected by the chiller appli-
cation.
• The Ethernet cable is not correctly connected.
• Network parameters are not correct (see the Ethernet/IP
Connection Problems section on page 56).
• There is an IP router between the equipment and the buil-
dign management system.
• BACnet Enable parameter in the PIC 5 Configuration
Menu is set to No.
To troubleshoot problems, try these measures:
• Open the metal casing of the 19XR PIC 5 controller and
verify that the blue BACnet dongle is correctly con-
nected.
• On the Ethernet connector, verify that the green LED is
ON and the orange LED is blinking
• Open a command window under Windows (Start, Exe-
cute, type cmd and press Enter), type the command ping
followed by the equipment IP address. The equipment
must respond.
• Open 19XR PIC 5 Configuration Menu (Service pass-
word required) and check BACnet parameters.
• Use the free software called BDT (BACnet Discovery
Tool) available on the internet (search bacnet bdt) and
install it on the PC. All equipment connected to the
BACnet network will respond to the “Who Is” command
sent by this tool. Find the equipment configured with the
BACnet device instance (1600001 for Carrier equip-
ment).
