General: Net Protocol
Extended Modbus Connector —
tor and CCN connector on PIC 5 controller can be configured
to be a Modbus connector:
Step 1: Configuration Menu Network Configuration,
Modbus Option set to Enable
Step 2: When the Modbus Server Type is set to 0(IP), Ether-
net connector will be the Modbus connector; when the Modbus
Server Type is set to 1(RS485), CCN connector will be the
Modbus connector.
Step 3: Wait 40 seconds; the controller will reboot automati-
cally to save the configuration change.
Extended Open Protocol Connector —
connector and CCN connector on PIC 5 controller can be con-
figured to be a Modbus connector (feature initiated in v3.2 soft-
ware) with the following steps:
Step 1: Configuration Menu ->Network Configuration, Mod-
bus Option set to Enable
Step 2: Modbus Server Type set to 0(IP), Ethernet connector
will be the Modbus connector; Set to 1(RS485), CCN connec-
tor will be the Modbus connector.
Step 3: Wait 40 seconds; controller will reboot automatically to
save the configuration change.
See Fig. I-L. Even if ethernet connector is configured to be
the extended Modbus connector, it still can be configured to
BACnet with BACnet dongle installed and BACnet option set
to enable.

The 19XR PIC 5 controller supports the
BACnet/IP —
BACnet protocol as B-ASC BACnet equipment over IP. In ad-
dition, BACnet on the PIC 5 controller supports the following
features:
• Optional properties such as Change of Value (COV),
Intrinsic Reporting, and Commandable properties on
some objects.
• The generation of limited alarm and event notifications
and the ability to direct them to recipients
• The tracking of acknowledgments of alarms from human
operators
• The adjustment of alarm parameters
• Read/write property for many objects
Installing the BACnet Dongle —
tion can be implemented at the factory or on-site. This section
is intended for on-site installation.
It is strongly recommended to disconnect the complete
power supply before any intervention. Disconnect the main
power supply with appropriate disconnect devices. Only per-
sonnel qualified to the level recommended in standard IEC
60364 (International Electrotechnical Commission) and trained
to do this may have access to electrical components.
