POINT-TO-MULTIPOINT CAPABILITIES

The OleumTech® DH2 Wireless Gateway plays an instrumental role in the OTC Sensor Network by wirelessly collecting critical process data from OTC nodes including Transmitters, I/O Modules, and other Gateways and storing them in its 1920-point Modbus register holding table. It also has the ability to carry out output commands to mapped outputs points.

PEER-TO-PEER CAPABILITIES

In the OTC Sensor Network, multiple Gateways can be deployed to a same network, creating an advanced peer-to-peer networking infrastructure. Each Gateway in the network can have its own set of end nodes and I/O points and can be peered with other Gateways in a network. By taking advantage of its high scalability and communication flexibility, users can gain a competitive edge by reducing material, labor, and engineering costs.

SERIAL INTERFACE

With the provided RS232/RS485 configurable Serial port, the DH2 can virtually interface with any third-party Modbus device. The DH2 can be configured as a Modbus Master, Modbus Slave, LevelMaster ASCII Slave, or ROC Link Master.

ADVANCED I/O MAPPING

The OTC Sensor Network is highly advanced enabling a DH2 or any other Gateway to take any input source or Modbus register and map it to an available output or to another register anywhere within its network. There are virtually no limitations as to how the OTC Network can be utilized for automation.

BreeZ® SOFTWARE

The DH2 Ethernet Wireless Gateway is configured using BreeZ Software by OleumTech, provided free of charge.
