● Existing Register Map: If you've already configured a modbus connector, this
property will let you choose from a list of available registers or to create a new
one with ModbusRegMapUri.
● ModbusRegMapUri: Specify the name of the register map to link with this
connector. Replace "xxx" with whatever the name of the register map is.
● Uri: To specify the Uri, enter the host, protocol, and port (default 502).
Supported Protocols
Protocol Type
Address
TCP/IP
modbus-tcp://host/
RTU over TCP/IP
modbus-rtutcp://host/
RTU over RS-485
modbus-rtu://ttyUSB0
To add a Modbus connector:
1. Navigate to and expand Connectors > Modbus in the Navigation tree.
2. Select + Add.
3. In the pop-up, select the Existing Register Map drop-down and select the file
you just uploaded.
4. (Optional) If you have not yet uploaded the register map file, you can supply a
ModbusRegMapURI.
5. The Uri field gives information on the Modbus address. You can leave
“modbus-tcp://” as the protocol address and replace “host” with the device’s IP
address.
6. Select Add when finished.
1.3.5 Adding Equipment and Data Points
Once you’ve added a floor object, you can then add equipment objects to the
hierarchy. These objects are discoverable through object discovery in Building
Operator Discovery.
The Equipment hierarchy level, although optional, provides flexibility to structure
the device level in Building Operator. Typically, the equipment corresponds to a
BACnet device; however, two or more building equipment of a BACnet device can
be mapped to two or more equipment in Building Operator Discovery.
Adding Equipment
To add an equipment object to a floor object, complete the instructions below:
1. Expand the Equip Tree in the Navigation pane.
2. Expand the site object, then select the right floor object.
