ADVANCED NETWORKING ARCHITECTURE
The DH3 Wireless Gateway plays a vital role in the OleumTech Wireless Sensor
Network. When used as a primary Gateway, it serves as the central collection point
of data, which then can be served to any Modbus Master device. The DH3 can
collect data from OleumTech wireless end nodes such as Wireless Transmitters and
Wireless I/O Modules in a “star network” or point-to-multipoint structure. What
sets the OleumTech Gateway apart from the rest of the competition is its ability to
wirelessly share data and control outputs amongst multiple Gateways in a same
network known as “peer-to-peer” architecture. Thus, OleumTech Wireless System
is highly scalable, allowing the creation of a basic network containing a handful of
end nodes to a much more robust network containing hundreds of wireless nodes
and Gateways stretched by many miles.
FLEXIBLE COMMUNICATION
The DH3 is equipped with two (2) serial ports that can be independently configured
using BreeZ® software as a Modbus Master, Modbus Slave, LevelMaster Slave, or
ROC-Link Master. In a typical deployment, a DH3 acts as a Modbus Slave device
that is connected to a Modbus Master device such as a RTU, PLC, HMI, DCS, or
long-haul radio system over Modbus Serial RS232/485 or TCP/IP connection. DH3
can also function as a Modbus Master device to collect critical process values from
a Modbus Slave device. The polled data can be served to a Modbus Master device
or can be shared over the air to another Gateway in a network.
MULTI-FUNCTION GATEWAY
DH3 is a Multi-Function Gateway. Unlike its predecessors, it has the ability to data
log. Data can be in the form of a triggered event logging and, or trending based on
a set interval. Data log can be stored on its internal RAM (not persistent) or
optional Industrial-grade Micro SD card (Serial # xxx and higher). The logged data
can be exported to a .CSV file using BreeZ® Software or via Web Server.
