The microprocessor-based multifunction device shall
provide the functions listed below.
Communications
The device shall be capable of communicating on both
the POWER LEADER commnet and Modbus RTU
communication protocols. It shall communicate all
metering and setup information polled from connected
POWER LEADER commnet devices to a host PC
equipped with Power Management Control System 5.0
software. This shall be a multitasking system, providing
event logging, alarm and event indication, energy
trending, and the collection of information on a
scheduled basis. The device shall also be capable of
communicating setup and control commands from the
host computer to the attached commnet devices.
Inputs/Outputs
The device shall accept input from up to eight POWER
LEADER commnet segments. Each commnet segment
shall support up to four POWER LEADER commnet
devices (not including POWER LEADER Repeaters
and Junction/Outlet Boxes).
The device shall provide RS485 input and output ports
with adjustable baud rate (1200, 2400, 4800 and 9600
baud, and 19.2 Kbaud) for communications on a
Modbus RTU protocol network.
The device shall have a four-character alphanumeric
high-contrast LED display and a four-key keypad on its
faceplate.
The device shall require control power of 85-265 volts
ac or 100-250 volts dc.
Configuration
The device configuration and all user-defined values
and settings shall be entered via the keypad. The device
shall be capable of being automatically configured.
Construction
The device shall be provided in a steel case with
provisions for communications connections on the
front of the case. Control power voltage connections
shall also be made on the front of the case. The device
shall be front mounted via mounting holes provided at
each end of the case.
