Step Description 1. Initial State: Homing 2.1 User presses Button PBO (X44) to RESET counter and HOME cylinders to retracted states. i.e. Sensors a0 (X40) and bo (X42) are activated. 2.2 All light bulbs turn off- e 2. User presses Button PBI (X45) Linear 2.3 Green Bulb (Y42) turns ON Actuator 2.4 Cylinder A extends (Y43) 2.5 Sensor al (X41) is activated 2.6 Cylinder A retracts (Y44) 2.7 Sensor a0 (X40) is activated 2.8 Cylinder B extends (Y45) 2.9 Sensor bl (X43) is activated 2.10 Cylinder B retracts (Y46) 2.11 Sensor bo (X42) is activated 2.12 Repeat the cycle (Steps 2.4 -2.11) 3 more times 2.13 Green Bulb (Y42) turns OFF and Red Bulb (240) turns ON 4 Table 2 - Requirement of Working Sequence Q.2 Refer to the information (Figure 1. Figure 2, Figure 3, Table 1, Table2), Group the motion sequence by the Cascade method. Design and write the NAIS FP-O PLC ladder diagram to do the working sequence, which is mentioned in Table 2. (35%) ii. Explain in details the design principle of your PLC program. (5%)
