Designed to meet specific control and safety requirements

We focus on gaining a deep understanding of how our clients’ processes operate, enabling us to provide robust PLC systems to improve efficiency and control, and enhance the profitability and reliability of their operations through automated industrial processes.

Our particular strength and expertise lies in the oil and gas industries, with a focus on ensuring PLCs are designed for robust and reliable operation in the most challenging industrial environments.

Ensuring Safety and Reliability

Safety systems are a priority in the PLC Systems we build - specifically programmed to detect abnormal conditions such as high temperatures or pressures and initiate emergency shutdown procedures to prevent accidents and protect equipment.

We have considerable experience in both High Availability and Safety PLC configurations, comprising redundant CPUs, redundant I/O systems and safety related I/O up to Safety Integrity Level (SIL)3.

These systems incorporate many of the industry standard communication protocols such as Profibus, Profinet, Profisafe, ControlNet, DeviceNet, Ethernet and Modbus (RTU and TCP).

Benefits of effective and bespoke PLC Systems include;

  • Increased efficiency and accuracy and precision: Streamline industrial processes, reduce manual intervention and optimise the execution of tasks in real-time.
  • Reduced Downtime: Identify faults quickly for efficient troubleshooting to maintain production.
  • Improved safety: Creating a safer working environment and meet regulations with safety critical functions.
  • Remote Monitoring and Control: Integrate with communication networks, enabling remote monitoring and control of industrial processes.
  • Data collection: Collect and analyse process data for performance monitoring, quality control, and continuous improvement initiatives.
  • Keeping Compliant: Meet regulatory requirements and industry standards by providing features for documentation, reporting, and traceability of processes.

World-leading Programmable Logic Controller (PLC) platforms we provide and maintain include;

  • Siemens
  • Rockwell
  • Honeywell
  • Eurotherm
  • Emerson
  • Mitsubishi
  • Red Lion

Client Major UK forging company


  • Furnace design, installation and commissioning
  • PLC based process automation system with touchscreen HMI.

Scope of project

The customer had a number of requirements for the new furnaces to comply with, in order to increase output and reduce operating costs.

Firstly, a close temperature tolerance of +/-10°C within the working envelope was required throughout the operating temperature range of 700°C to 1250°C, to allow processing of ferrous…
