A classic Supervisory Control and Data Acquisition (SCADA) system typically consists of a central computer and many networked PLCs, with intermediate computers between them to perform coordination and supervisory roles. The PLCs perform data acquisition and control locally, while the central PC provides the HMI, data logging, data processing and decision making.

SCADA systems are evolving with the emergence of Programmable Automation Controllers (PACs). A PAC combines the flexibility and power of a PC with the robustness of a PLC, packing these strengths into a single device. This synergy strengthens a SCADA network: Its network topology is simplified while its capabilities are broadened.

Today, there is pressure on industry to reduce cost, increase efficiency, and improve quality. ICON Technologies specialises in solutions that push the boundaries of what’s achievable through traditional SCADA networks. We can provide robust, 24/7 solutions to meet requirements that traditional PLC-based systems struggle with, such as:

  • High-speed acquisition and generation of signals (up to the megahertz regime)
  • Deep memory for data logging
  • Real-time data analysis and decision-making
  • Integrated machine vision and multi-axis motion control
  • Flexibility to quickly adapt the system to suit changing needs.

These characteristics are typically found in, but are not limited to:

  • Pilot plants and research facilities;
  • Control systems for small-to-medium scale plants that produce boutique or specialised products; and
  • Specialised control and automation sub-systems that exist within larger, more traditional environments.

If you are considering a new SCADA system, talk to ICON Technologies to find out if your requirements are better met by a PAC-based system.

Nevertheless, traditional PLC-based SCADA systems will continue to play an important role in many sectors of the measurement and automation market. ICON Technologies can help you to integrate a new PLC-based SCADA system, or we can help you to upgrade an existing SCADA system.
