Energy Savings & Efficiency
Did you know?
Many energy-efficient automation upgrades may qualify for SEAI or government energy support schemes.
Talk to your energy advisor or contact us to learn more.
Our automation solutions can unlock significant energy savings — especially with:
Load scheduling to reduce peak energy costs
PID control on extractors and HVAC systems
Smart compressor and dryer sequencing
Remote monitoring and analytics for ongoing optimisation
Control System Support & Troubleshooting
Fast fault diagnosis and repair for Allen-Bradley, Siemens, Schneider, Omron, and other leading PLC platforms.
Using secure remote access tools, we can resolve many issues without a site visit — reducing costs and downtime. Whether you’re running a legacy system (Allen-Bradley SLC 500 / MicroLogix, Siemens S7-200 / S7-300) or the latest platforms (ControlLogix, Siemens S7-1200 / S7-1500), we provide expert support to keep your production running.
Typical services include:
Program fault finding & corrections
Control panel fault finding
Communication network troubleshooting (EtherNet/IP, Profinet, Profibus, serial, etc.)
I/O and sensor diagnostics
Remote online support with minimal disruption
Replacement or reconfiguration of VFDs (Variable Frequency Drives)
HMI and SCADA fault finding
Control Panel Retrofits & Upgrades
Replace obsolete hardware with modern Allen-Bradley or Siemens PLC systems for improved reliability and easier maintenance.
We manage the entire process - from component selection and panel building to programming, commissioning, and full documentation.
Benefits of upgrading:
Easier access to spare parts
Improved diagnostic tools
Future-proofing for production expansion
Conversions & Migrations
Upgrade older legacy PLC models to modern platforms for better performance, compatibility, and efficiency.
We specialise in converting legacy hardware to Allen-Bradley or Siemens solutions, ensuring minimal disruption during changeover.
Common reasons for migration:
Spare parts no longer available
Integration with modern HMIs and SCADA systems
Improved energy efficiency and control
Discontinued OEM support for legacy hardware
Remote Support Packages
Flexible PLC support plans to match your needs - from pay-as-you-go troubleshooting to fixed monthly contracts with guaranteed response times.
Nationwide coverage means we can help even when an on-site visit isn’t possible
