Zencus Gateway Overview

  • The Zencus Gateway is the interface between the Zencus Wireless Network and the Zencus Data Visualization Suite or client SCADA/ DCS system.
  • The Gateway can be configured as the main controller for a network of 200 - 300 Zencus Field Transceivers (wireless RTUs) or directly receive data from 200+ Zencus Mono-Transmitters, giving virtually unlimited data acquisition and redundancy options.
  • IEC61331-3 complaint PLC functionality supporting structured text, function block diagrams, instruction lists, ladder diagrams and sequential function charts.
  • The integral CPU authenticates and synchronises Field Transceivers on the network (2.4 GHz radio model), decrypts, logs, validates and error checks received data, and provides network diagnostics.
  • The Gateway uses industry standard protocols including OPC and MODBUS utilizing Ethernet and RS232/RS485 interfaces and for older legacy systems can be configured with analogue and digital outputs.
  • The Zencus Gateway can be configured for input into the Zencus Data Visualization Suite or into an existing SCADA/DCS system (via an RTU or the client LAN), optionally, data can be fed into both systems simultaneously.
  • The Gateway can be mains or 24VDC powered and has an optional power pack which includes battery, solar, wind or a combination charger and sophisticated power management system.

System Architecture

  • Zencus Mono-Transmitters at remote well sites transmit to a local Field Transceiver, with up to 200 Mono- Transmitters linking to a single Transceiver.
  • The Field Transceiver transmits received data over longer distances to the Zencus Gateway, directly or via additional Field Transceivers acting as mesh nodes, depending on positioning and topography. The use of a long distance mesh network ensures multiple transmission routes to the Gateway.
  • The physical number of Field Transceivers permissible in a Zencus network has a theoretical limit of 65,535 but practical considerations such as bandwidth limit individual networks to 100-300 units. Multiple independently addressed networks can co-exist and operate in parallel for larger installations.
  • The Zencus Gateway manages the network and delivers data into the Zencus Data Visualization system, the client SCADA system (directly or via a RTU) or both systems simultaneously when operating in parallel.
