Rangkaian pemograman PLC untuk Packing Machine :
Step 1 : ( Feeder Forward to 1 )
If Feeder REV Limit = ON And Lifter UP Limit = ON And Switch Start = ON Then Cylindrical Feeder Forward = ON.
Step 2 :
1. If Cylindrical Feeder Forward = ON And Feeder FWD Limit = ON Then Cylindrical Feeder Reverse = ON.
2.a. If Cylindrical Feeder Forward = ON And Feeder FWD Limit = ON Then Cylindrical Lifter DOWN = ON.
2.b. If Lifter MID Limit = ON Then Cylindrical Lifter DOWN = OFF.
Step 3 : ( Feeder Forward to 2 )
If Feeder REV Limit = ON And Lifter MID Limit = ON Then Cylindrical Feeder Forward = ON.
Step 4 :
1. If Cylindrical Feeder Forward = ON And Feeder FWD Limit = ON Then Cylindrical Feeder Reverse = ON.
2.a. If Cylindrical Feeder Forward = ON And Feeder FWD Limit = ON Then Cylindrical Lifter DOWN = ON.
2.b. If Lifter LOW Limit = ON Then Cylindrical Lifter DOWN = OFF.
Step 5 : ( Feeder Forward to 3 )
If Feeder REV Limit = ON And Lifter MID Limit = ON Then Cylindrical Feeder Forward = ON.
Step 6 :
1. If Cylindrical Feeder Forward = ON And Feeder FWD Limit = ON Then Cylindrical Feeder Reverse = ON.
2.a. If Cylindrical Feeder Forward = ON And Feeder FWD Limit = ON Then Cylindrical Lifter UP = ON.
2.b. If Lifter UP Limit = ON Then Cylindrical Lifter UP = OFF.
