(a) The instrumentation will be controlled by a PLC as shown in Figure Q5 forms part of an industrial assembly process and is used for moving components from point A to point B. Three 5/2 way spring return solenoid valves, and three linear actuators are employed. The sequence is initiated by a manual PUSH BUTTON switch. The process for actuator is: (C+B+ delay 1.5s|C-B-A+|delay 2s|B+C+ldelay 3s|B-A-C-) x 20 Rajah S5 Figure Q5 Design the appropriate SEQUENCE diagram (5 markah /marks) (b) Formulate the suitable SET/RESET switching functions for both secondary variables and actuators (c) (5 markah Imarks) Develop the corresponding LADDER diagram (5 markah /marks)
