Yokogawa STARDOM Logic Designer / FA-M3 WideField3 for Bottle Filling
Yokogawa's primary IDE for FA-M3 PLCs is WideField3, a structured-text-and-FBD-leaning environment that reflects Yokogawa's process-automation pedigree more than its discrete-PLC ambitions. STARDOM (the FCN / FCJ hybrid PLC / RTU line) is programmed in Logic Designer, a separate tool aligned to IEC 61131-3 and EtherNet/IP / Modbus integration. CENTUM VP — the headline DCS — is configured rather than programmed via System View, with control logic expressed in function-block templates rather than ...

Understanding Sequential Function Charts (SFC) for Bottle Filling
Sequential Function Chart (SFC) is a graphical language for programming sequential processes. It models systems as a series of steps connected by transitions, ideal for batch processes and machine sequences.
Execution Model:
Only active steps execute their actions. Transitions define conditions for moving between steps. Multiple steps can be active simultaneously in parallel branches.
Core Advantages for Bottle Filling:
- Perfect for sequential processes: Critical for Bottle Filling when handling intermediate to advanced control logic
- Clear visualization of process flow: Critical for Bottle Filling when handling intermediate to advanced control logic
- Easy to understand process steps: Critical for Bottle Filling when handling intermediate to advanced control logic
- Good for batch operations: Critical for Bottle Filling when handling intermediate to advanced control logic
- Simplifies complex sequences: Critical for Bottle Filling when handling intermediate to advanced control logic
Why Sequential Function Charts (SFC) Fits Bottle Filling:
Bottle Filling systems in Packaging typically involve:
- Sensors: Bottle presence sensors (fiber optic or inductive) for container detection, Level sensors (capacitive, ultrasonic, or optical) for fill detection, Load cells for gravimetric (weight-based) filling
- Actuators: Servo-driven filling valves for precise flow control, Pneumatic pinch valves for on/off flow control, Bottle handling star wheels and timing screws
- Complexity: Intermediate to Advanced with challenges including Preventing dripping and stringing after fill cutoff
Programming Fundamentals in Sequential Function Charts (SFC):
Steps:
- initialStep: Double-bordered box - starting point of sequence, active on program start
- normalStep: Single-bordered box - becomes active when preceding transition fires
- actions: Associated code that executes while step is active
Transitions:
- condition: Boolean expression that must be TRUE to advance
- firing: Transition fires when preceding step is active AND condition is TRUE
- priority: In selective branches, transitions are evaluated in defined order
ActionQualifiers:
- N: Non-stored - executes while step is active
- S: Set - sets output TRUE on step entry, remains TRUE
- R: Reset - sets output FALSE on step entry
Best Practices for Sequential Function Charts (SFC):
- Start with a clear process flow diagram before implementing SFC
- Use descriptive step names indicating what happens (e.g., Filling, Heating)
- Keep transition conditions simple - complex logic goes in action code
- Implement timeout transitions to prevent stuck sequences
- Always provide a path back to initial step for reset/restart
Common Mistakes to Avoid:
- Forgetting to include stop/abort transitions for emergency handling
- Creating deadlocks where no transition can fire
- Not handling the case where transition conditions never become TRUE
- Using S (Set) actions without corresponding R (Reset) actions
Typical Applications:
1. Bottle filling: Directly applicable to Bottle Filling
2. Assembly sequences: Related control patterns
3. Material handling: Related control patterns
4. Batch mixing: Related control patterns
Understanding these fundamentals prepares you to implement effective Sequential Function Charts (SFC) solutions for Bottle Filling using Yokogawa STARDOM Logic Designer / FA-M3 WideField3.
