PowerCommand
Modbus Gateway
(FT-10) LON Input/Output

Description
The PowerCommand Modbus Gateway (also called ModLon gateway) is used to interface PowerCommand networks to devices and systems that communicate in Modbus communication protocol. The Modbus Gateway (ModLon gateway) provides an Echelon LonWorks to Modbus RTU conversion via an RS232 serial connection. The gateway supplies predefined Modbus RTU registers for PowerCommand network components. Selection of the gateway configuration is done via Echelon LonMaker software, which is also used for the PowerCommand Network installation.

Features
· Converts Echelon LonWorks data streams to register maps that can be read by equipment communicating in Modbus RTU format. FTT-10 Transceiver with plug-in terminal block. Modbus port EIA-232 configuration. Capable of displaying data from PowerCommand genset controls, transfer controls, CCM and DIM modules. Service button and LED indicators Configured to PowerCommand networks using Echelon LonMaker for Windows. Operates on 12VDC, and is available with plug-in AC power supplies at various voltage levels. UL listed and labeled; CSA certified; CE Marked. FCC Part 15 Class B, CB Scheme report and certificate Warranty. PowerCommand Controls are supported by a worldwide network of independent distributors who provide parts, service and warranty support.
