Start with process risk.
Then define the control architecture.

Start with pump curves, design flow and head, motor data, duty/standby sequence, instruments, power conditions, enclosure environment and SCADA interfaces.

Evaluate VFDs when normal demand varies and speed control can meet flow or pressure requirements while respecting minimum speed, equipment limits and bypass philosophy.

Provide the conveyor layout, zone and motor lists, flow rules, safety architecture, equipment handshakes, identification requirements and recovery philosophy.

Release one approved BOM, drawing and software baseline, document the option matrix and control every substitution or revision before repeat production.

Installation zones, washdown and cleaning chemicals, condensation, enclosure material, recipe governance, traceability and hygienic field responsibilities all affect the scope.

Review dust, heat, vibration, corrosion, fault level, motor-cable distance, maintenance access, remote I/O environment and the plant shutdown procedure.
