Parameters

NameTypeUsageDescription
In_BreadFeederBOOLInput1 when bread is detected.
In_Ingredient1BOOLInput1 when ingredient 1 is present.
In_Ingredient2BOOLInput1 when ingredient 2 is present.
In_Ingredient3BOOLInput1 when ingredient 3 is present.
In_Condiment1BOOLInput1 when condiment 1 is present.
In_Condiment2BOOLInput1 when condiment 2 is present.
Out_ConveyorMotorBOOLOutput1 when conveyor motor is active.
Out_AssembleMotorBOOLOutput1 when assembly motor is active.

Behavior

  1. On the rising edge of In_BreadFeeder, the internal SliceCount is incremented by 1.
  2. Out_ConveyorMotor is set to 1 while In_BreadFeeder is 1.
  3. Out_AssembleMotor is set to 1 if SliceCount is greater than or equal to 2 AND In_Ingredient1 is 1 AND In_Ingredient2 is 1 AND In_Ingredient3 is 1 AND In_Condiment1 is 1 AND In_Condiment2 is 1; otherwise, it is 0.

Edge Cases

  • SliceCount should not increment if In_BreadFeeder is continuously 1.
  • Out_AssembleMotor stays 0 if any ingredient sensor is 0 even if SliceCount >= 2.

Constraints

  • SliceCount must be initialized to 0.
  • SliceCount should persist across AOI scans.
  • BreadFeederPrev must store the state of In_BreadFeeder from the previous scan for edge detection.
