/Problem
Design a PLC-controlled multi-station sorting line with strict safety requirements, including emergency stops, light-curtain interlocks, and recoverable faults, with seamless switching between manual and automatic modes.
/Approach
- 01Modelled the system using a Sequential Function Chart (SFC) and implemented control logic in S7 ladder logic.
- 02Developed a dual-mode HMI interface supporting manual jog controls and fully automatic operation.
- 03Implemented latched fault handling with explicit operator acknowledgement for safe recovery from interlocks.
- 04Validated the control program using a Factory I/O simulation prior to physical testing.
/Results
- Verified 100% of safety interlocks under simulated fault conditions.
- Achieved zero deadlocks across 50+ consecutive automatic cycles.
- Enabled seamless mode switching with no loss of system state.
