DCS Engineering and Configuration
Control strategy, graphics, I/O database, sequence logic, alarm configuration and Factory Acceptance Test — delivered by engineers who also commission the system on site.
Configuration is where a control system either becomes operable or becomes a decade of workarounds. We deliver configuration as an engineering discipline with reviewable deliverables at each stage, not as a drawing-to-database transcription exercise.
Scope of Configuration Work
| Work package | Content |
|---|---|
| Control strategy configuration | Regulatory loops, cascade and ratio structures, override and selector logic, tuning framework |
| Operator graphics | Process displays, navigation hierarchy, faceplates, trends and alarm presentation consistent with the site HMI standard |
| I/O database build | Point configuration, scaling, engineering units, signal conditioning, ranges and channel assignment |
| Sequence and batch logic | Phase logic, state transitions, permissives, holds and recovery paths |
| Interlock and protective logic | Cause-and-effect implementation, permissive and trip logic within approved safety governance |
| Alarm configuration | Priority, limits, deadband and delay configured against the site alarm philosophy from day one |
| Factory Acceptance Test | Test specification, execution, punch list management and close-out documentation |
Alarm Configuration Is Done Properly at Build Time
Most alarm problems are created during configuration and discovered years later in operation. We configure alarms against the site alarm philosophy at build time — applying rationalisation principles rather than defaulting every point to a high priority and leaving the plant with an unmanageable alarm load on day one.
Where a plant has no alarm philosophy in place, we can develop one as part of the project, or apply our alarm management system to establish a governed baseline.
