PLC sequence and machine states
Translate the agreed process into explicit states, transitions, permissives, alarms and recovery behavior. The final sequence should be reviewed against the machine's actual operating procedure.

PVD Coating Process Automation
PVD process controls can organize machine states, cycle steps and available vacuum or process signals according to the coating equipment design. Automation scope depends on the equipment, operating sequence, existing controls and process requirements. Share the machine details and desired outcome to define a suitable control approach.
Application overview
PVD process controls can organize machine states, cycle steps and available vacuum or process signals according to the coating equipment design.
Typical requirements to define
- Coating system and existing controller details
- Documented cycle stages and permissives
- Vacuum and process signals available from installed instruments
- Recipe, alarm and batch handling needs
Example process sequence
- Check chamber, utilities and system readiness
- Run the configured preparation and cycle stages
- Monitor available vacuum and process feedback
- Complete the cycle and signal the required release state
- Record or report faults for controlled recovery
Machine states and operating sequence
Document the machine cycle, operator actions, required permissives, abnormal conditions and safe recovery path before mapping them to controller logic.
Operator interface and alarms
An HMI may show mode, step, status, setpoints and actionable alarm information. Screen behavior and operator permissions should match the plant's procedures.
Safety and fault handling
Safety functions must be designed for the risk assessment and applicable machine requirements. Standard PLC logic should not be treated as a substitute for safety-rated hardware or a validated safety design.
Vacuum and process instrumentation
Control interfaces and limits must follow the installed vacuum equipment, sensor ranges and validated process requirements. No specific coating result or process capability is assumed.
