SECTION 1
About the controllers
This section provides a description and specifications—including the
BACnet and Modbus options—for models KMD-5205 LANLite and
KMD-5270 WebLite controllers. Safety information is included also.
Review this material before installing or operating the controllers.
Introduction
The KMD-5205 and KMD-5270 both provide programmable control and
high-level LAN connectivity for facilities management systems. These powerful,
direct-digital-controllers operate on a peer-to-peer, token passing protocol, using
either Ethernet or EIA-485 networks.
◆
Ethernet for KMD Tier 1 controllers and optional BACnet 8802.3 devices.
◆
EIA-485 for either KMD Tier 2 or Modbus RTU controllers
The operating software in the controllers use a high level, easy to learn
programming language to ensure reliability, rapid programming and
compatibility with future KMC system enhancements.
Internet operation
KMD-5270 models only
The embedded internet server in the KMD-5270 models make them ideal
controllers for schools and businesses with an Ethernet infrastructure. System
operation can be changed using a standard internet browser such as Netscape or
Microsoft® Internet Explorer. In addition to changing settings, you can view
system groups, trend and runtime logs with the browser.
BACnet 8802-3
option
Models with the BACnet option adds open-system functionality to these
controllers.
◆
BACnet devices see input, output and variables in the controller as BACnet
input, output and value objects.
◆
When installed on the same Ethernet broadcast domain segment as a
BACnet 8802-3 network, use Control Basic to retrieve data from any
accessible BACnet object on the internetwork.
Modbus option
Connect directly to Modbus RTU equipment with the Modbus option. Modbus
registers are mapped to variables in the controller that are then available for use
by other KMD controllers, BACnet devices or Control Basic.
