Requirements and current state
Review material flow, motor loads, stop causes and panels. Define sequential start/stop, fill-level and blockage scenarios.
Technical design and development
Design PLC, HMI and drive interfaces for the site. Combine feeding permissives, motor states and alarm priorities in a functional specification. Assess safety circuits separately.
Testing and implementation
Separate dry tests and loaded operation. Check power recovery, communication loss and restart after partial stops. Capacity changes require real plant measurements.
