Access to the controllers from BACnet
To access the BACnet licensed controller, use a BACnet operator workstation such
as BACstage.
◆
The WebLite will appear in the BACstage device list but cannot be selected.
Its objects are not accessible for configuration from the BACstage
Object
menu.
◆
The configured points within the WebLite are the only points visible in
BACnet.
◆
In BACstage, use
BACnet Read/Write Property
under the
System
menu in
BACstage to manually view or change properties.
◆
In TotalControl the BACnet licensed controllers are added to the Network
Manager list.
◆
KMC BACnet controllers and third-party devices may read and write to the
objects in the WebLite with off-panel reads and writes.
Setting up for
Modbus networks
These topics apply only to the following models:
Set the following Modbus communication parameters with HCM. All Modbus
devices connected to the same network—including the KMD-5205 and KMD 5270
models—must be set to the same mode, baud and parity.
Programming for
Modbus in
WinControl XL Plus
Use WinControl XL Plus to map Modbus registers to variables in the KMD-5205
and KMD-5270 Modbus licensed controllers. Once the registers are mapped to
variables, the variables are handled with Control Basic to read from and write to
the registers. The procedures for mapping the registers to variables are covered in
WinControl XL Plus help and the WinControl XL Plus Reference manual.
Note
WinControl XL Plus 2.1 or later is required to map Modbus registers to
variables in the KMD-5205-005 and KMD-5270-005 controller.
