Services

Controls engineering, end to end.

From first specification to years of support — for end clients directly, and inside integrators’ delivery teams. Delivered from the UK, across the UK.


01

PLC software engineering

Structured, testable control software in Siemens TIA Portal for S7-1500 and S7-1200, including fail-safe applications. Written to be read: consistent structure, meaningful naming, and documentation that survives handover to the next engineer.

Typically includes

  • New-build application software
  • Fail-safe (F-system) applications
  • Standardisation and code libraries
  • Code review and rework
  • Simulation and offline testing

02

HMI & SCADA

Operator interfaces that reflect how the plant actually runs. Clear screens, honest alarms, and navigation an operator can learn in a shift — built in SIMATIC WinCC.

Typically includes

  • Panel and PC-based WinCC applications
  • Alarm philosophy and rationalisation
  • Screen standards and templates
  • Access levels and user management
  • Migration of ageing HMI applications

03

Commissioning & site services

FAT, SAT and go-live, run with discipline. I/O checkout that is actually complete, changes recorded as they happen, and a structured handover at the end — plus cover when production can’t stop.

Typically includes

  • FAT and SAT execution
  • I/O checkout and loop testing
  • Go-live and ramp-up support
  • Shutdown and changeover cover
  • Site records and structured handover

04

Material handling & logistics

Our background is high-throughput sortation, conveying and warehouse automation — systems where seconds matter and edge cases arrive by the thousand. We write control that keeps product moving.

Typically includes

  • Sortation and conveyor control
  • Merge, divert and tracking logic
  • Throughput analysis and tuning
  • WMS / WCS interface integration
  • Emulation and virtual commissioning support

05

Upgrades & migrations

Planned moves from legacy Simatic platforms to TIA Portal, sequenced around production. Obsolescence handled before it bites — with rollback points, not leaps of faith.

Typically includes

  • S7-300 / S7-400 to S7-1500 migrations
  • Classic STEP 7 to TIA Portal conversions
  • Hardware obsolescence surveys
  • Phased cutover planning
  • Post-migration verification

06

Ongoing support

Remote and on-site support for installed systems: fault-finding, modifications and agreed response. Small changes handled properly — tested, documented and version-controlled.

Typically includes

  • Remote diagnostics and fault-finding
  • Modifications and enhancements
  • Agreed response arrangements
  • Documentation and backup discipline

07

Engineering tooling & software

We treat our own discipline as something to automate. Alongside project delivery we build software tools — for ourselves and for clients — that take friction out of controls engineering: consistency checks, bulk engineering-data handling, and utilities that make large TIA Portal projects navigable.

Typically includes

  • Bespoke engineering utilities for your team
  • Project consistency and standards checking
  • Bulk data preparation and handling
  • Documentation generation from project data
  • Prizm — our desktop companion for TIA Portal
