SCADA (Supervisory Control and Data Acquisition) is the most significant subsystem of NanoConnect24.7™ that allows industrial organizations to:

• Control industrial processes locally or remotely
• Monitor, gather, and process real-time data
• Achieve high-performance data archiving
• Efficiently analyze process values (trends) and messages (alarm control)
• Interact with a wide range of devices using extended communication infrastructure

Water treatment plants  operations are difficult to model, as control systems must respond to a variety of analog and digital data. To optimize the processes, this data must be gathered, integrated, and fed to analytical tools that employ data-driven methods for fault detection, variable prediction, and advanced control algorithms system data ranging from power supply and tank levels to pump status and sludge weight.

The data collection and redistributes data using DataHub technology in each plant and in the iBress cloud system. In the plants, a wireless gateway device running Skkynet’s ETK (Embedded Toolkit) maintains a secure connection via DHTP (datahub transfer protocol) to a special cloud-enhanced version of the DataHub running on the iBress cloud system. The ETK and iBress exchange data in real time through a secure SSL connection, with no firewall ports open at the plant.

Sensors and devices in the plant send their data to PLCs, which pass it 12 times per minute to the gateway via the Modbus protocol. The ETK  running on the gateway receives the data from all PLCs and aggregates it into a single, unified data set. It then sends the collected data to iBress at a more moderate rate of once per minute to conserve bandwidth and system resources. Any alarms that come through are immediately passed on to iBress over a separate channel.

iBress is connected to HMI displays in the offices of plant personnel, managing engineers, and regulatory agencies, giving them a complete view of the whole system, with up-to-the-minute readings on every sensor and device. iBress also sends emails for any alarms or failure notifications and logs the data to databases and CSV files. This allows NanoConnect24.7™  to respond to alarms as necessary, maintain records of all activity, and share selected data with their clients and contacts as needed.
