Solution
Smart Automation: PLC, SCADA and Modernization
Siemens PLC and SCADA engineering, and migration of ageing control systems without losing the process knowledge built into them.
Modernize control without re-learning the plant.
What this addresses
- Controllers past support with no spares and no one left who wrote the logic
- Undocumented changes made over years of production
- HMI screens that operators have learned to work around
- Migration risk that keeps getting deferred
What we build
PLC programming
Siemens TIA Portal and SIMATIC, structured and documented so the next engineer can read it. Logic is reviewed with the people who run the line.
Legacy migration
Existing logic is captured and understood before anything is replaced. The process knowledge in an old program is usually the most valuable thing in the cabinet.
SCADA and HMI
WinCC and WinCC Unified screens built around what the operator must decide, with alarm rationalisation so that alarms mean something again.
Commissioning discipline
FAT before it ships, SAT on site, operator and maintenance training, and documentation handed over as a deliverable rather than a promise.
Changeover planning
Cutover is planned around your shutdown window. Where possible the new system runs in parallel before it takes control.
Technology
- Siemens TIA Portal
- SIMATIC S7-1200 / S7-1500
- WinCC and WinCC Unified
- Allen-Bradley and Mitsubishi where required
- OPC UA
How it integrates
- Existing field devices and wiring are reused wherever they are sound
- Safety functions are engineered and reviewed separately from process logic
- You receive the source, the documentation and the rights to both
Common questions
Can the system integrate with existing Siemens PLCs?
Yes. Most work is on plants that already run Siemens controllers, and the usual task is extending or modernizing what is there rather than replacing it. Allen-Bradley, Mitsubishi and Schneider controllers are also supported where a plant is mixed.
Will the plant need to stop for implementation?
Most of the work happens off-line: engineering, configuration and factory acceptance testing before anything reaches your floor. On-site work is planned around a shutdown window you choose, and the scope of that window is agreed in writing before commissioning.
