Engineering Capability — Practical Delivery, Not Theory

Siemens TIA Portal PLC programming and industrial control systems
PLC Engineering

PLC Engineering

Industrial PLC work on live production systems

  • Siemens TIA Portal (S7-1200 / S7-1500)
  • Recovery, modification, and stabilisation of legacy or undocumented logic
  • HMI screen graphics (winCC, Unified, FactoryTalk View)
  • IEC 61131-3 (ST, FBD, LAD) structured code aligned with long-term support

Outcome:

Systems that run predictably, can be handed over, and don't generate callbacks.

HMI / SCADA Development

HMI / SCADA Development

Operator-focused HMI and SCADA systems

  • WinCC / WinCC Unified and industrial HMI platforms
  • Alarm management, navigation standards, ISA-aligned screen structures
  • Clean-up and rationalisation of inherited or inconsistent HMI's

Outcome:

Interfaces operators trust — not ones they work around.

Commissioning & Engineering Support

Commissioning & Engineering Support

Hands-on delivery support when projects are at risk

  • On-site and remote commissioning support
  • Short-term capacity injection during peak or stalled phases
  • Support through FAT, SAT, final delivery, and handover

Outcome:

Commissioning phases that move forward instead of dragging on.

Common Questions

Practical answers to typical engagement queries

Primarily Siemens TIA Portal (S7-1200/S7-1500), Rockwell Studio 5000, and Beckhoff TwinCAT 3. I also work with Mitsubishi, Schneider, and Omron systems where required. If your platform isn't listed, get in touch — I can often accommodate specialist requests.
Yes. Remote support covers diagnostics, program modifications, and ongoing technical backup. On-site presence is required for commissioning, FAT/SAT, and physical integration work.
Initial response within 1–2 working days. For urgent commissioning support, lead time is typically 2–4 weeks depending on scope and location. Same-day response available for existing clients.
Yes. While based in the Midlands, I regularly travel UK-wide for commissioning projects, FAT support, and specialist delivery work. International projects considered on a case-by-case basis.
OEMs, system integrators, and end users across manufacturing, marine, energy, and process automation. Experience spans production lines, offshore systems, material handling, and safety-critical applications.
Weekend commissioning can be arranged to minimize production disruption. Emergency callout rates apply outside standard hours (Mon–Fri, 9am–5pm). Discuss urgency during initial contact.
