Automation, control and industrial systems
Practical engineering work across industrial control, operational technology, drive systems, plant communication networks and data-driven monitoring, with a focus on diagnostics, recovery and reliability.
About
I am an engineering leader and hands-on controls specialist with a combined background in industrial automation, operational technology and IT systems. My work sits between practical fault investigation, control-system recovery, industrial communication, asset reliability and engineering team leadership.
My experience has been built around real operational environments where PLCs, HMIs, VFDs, SCADA-related assets, industrial networks, Windows-based control systems and legacy equipment need to be investigated, restored, tested and returned to service safely.
I combine hands-on diagnostics with wider engineering judgement: operational risk, reliability, maintainability, configuration control, documentation, technical communication, spares strategy and continuous improvement.
Professional Experience
My professional experience covers industrial automation support, control-system diagnostics, engineering team leadership, OT/IT recovery, maintenance support and technical coordination across operational industrial environments.
Operational engineering support
Experience supporting control, automation and SCADA-related assets across operational environments where equipment reliability, safe recovery and clear technical communication are critical.
Maintenance and recovery
Reactive, corrective and preventive maintenance support, including technical fault escalation, operational recovery, controlled testing and return-to-service of critical equipment.
Legacy and obsolete assets
Investigation, repair, refurbishment and recovery of current, legacy and obsolete control-system assets including PLCs, HMIs, VFDs, I/O modules, sensors, communication interfaces and electronic assemblies.
Technical coordination
Technical work-scope development, repair planning, spare-parts evaluation, supplier coordination, progress monitoring, handover communication and technical reporting.
Technical Competence
Technical competence built through hands-on investigation, integration, diagnostics and recovery of industrial control, automation, drive, communication and data-monitoring systems.
Control-system diagnostics and recovery
Hands-on investigation, diagnostics, repair, refurbishment and operational recovery of PLC, HMI, VFD, supervisory control, electrical and electronic control assets.

Instrumentation and monitoring
Integration and testing of analogue and networked instrumentation, Modbus environmental sensors, power and energy analysers, signal scaling and PLC data processing.
IT & Legacy Systems
My long-term IT systems background gives me a practical advantage when working with older and obsolete industrial control environments.
Many legacy SCADA and control systems are not only PLC-based; they often depend on Windows workstations, local applications, serial interfaces, archived configurations, old network settings, backup media, storage devices and unsupported operating systems.
Windows-based control environments
Practical support of Windows server and workstation environments, current and legacy operating systems, software installation, configuration, backup, recovery and technical troubleshooting.
System and data recovery
Operating-system recovery, file-system recovery, data restoration, backup recovery, storage troubleshooting and service-continuity support for business-critical and control-related systems.
Network and remote-access support
IP-based networks, network devices, Windows Remote Desktop access, device connectivity, legacy communication arrangements and practical fault isolation across IT/OT boundaries.
Obsolete SCADA-related assets
Fault investigation where the issue sits between control hardware, operating system, application software, communication interface, network configuration and original system backups.
Leadership & Management
My leadership experience is built around technical responsibility rather than purely administrative management. I have led engineering and technical teams in environments where decisions affect fault recovery, safety, quality, delivery time and customer confidence.
Technical leadership
Work prioritisation, technical decision-making, engineering supervision, troubleshooting guidance and support for engineers dealing with complex control-system and operational faults.
Safety and risk
Health & Safety leadership through task briefings, dynamic risk assessment, method statements, safe working practices, active monitoring and accountability during engineering work.
People and competence
Mentoring, structured technical coaching, practical assessments, interviews, staff development and knowledge sharing to build capable engineering teams.
Delivery and improvement
Resource coordination, supplier communication, customer-facing technical updates, documentation, maintenance recommendations, standardised diagnostic processes and continuous improvement.

Multi-vendor industrial automation prototype for controlled water tank filling and emptying, integrating Siemens PLC/HMI, ABB PROFIBUS drive control, Schneider CANopen drives, Festo PROFIBUS valve control, Modbus RTU instrumentation, SCADA supervision and InfluxDB logging.
System operation
The Siemens S7-1214 PLC controls the tank filling and emptying sequence. ABB ACS350 / ACS355 drives handle filling pump control over PROFIBUS DP, while Schneider ATV320 drives support discharge control over CANopen. The Festo valve terminal is connected over PROFIBUS and sequences inlet and outlet valves. The power network analyser is connected over Modbus RTU for electrical measurements, while the H₂S, temperature and humidity sensor is also connected over Modbus RTU. Internal temperature and humidity are measured through an analogue I/O sensor. The process is operated locally from the Siemens TP700 HMI and monitored remotely through SCADA, with operational data logged in InfluxDB.
Networks: PROFINET, PROFIBUS, CANopen, Modbus RTU and AS-i via PROFIBUS / AS-i gateway.
Multi-vendor industrial automation variant using PROFINET for ABB drive communication while also integrating Siemens PLC/HMI, Schneider CANopen drives, PROFIBUS field devices, Modbus RTU instrumentation, AS-i field detection, SCADA supervision and InfluxDB data logging.
System operation
This variant keeps the same PLC, HMI, SCADA, CANopen, Modbus RTU and AS-i structure, but uses PROFINET for ABB drive communication through FENA-11 and FENA-21 adapter modules. The PLC coordinates pump control, valve sequencing, tank-level response, drive status monitoring and fault reset functions. Process values, alarms, electrical measurements from the Modbus RTU power analyser, environmental values from the Modbus RTU H₂S / temperature / humidity sensor, and analogue temperature / humidity values are displayed on the HMI and SCADA dashboard, with historical data stored for trend review.
