Fundamentals and Practical Training of PLC Applications – Sequential Control Based on Timers

Practical Task:There are three motors that need to be started sequentially with a 10-minute interval. Each motor runs for 2 hours before automatically stopping. There is a stop button that can halt the operation of all motors. Write a PLC program.Steps:1. Assign I/OStart X0; Stop X1; Motor A uses Y0; Motor B uses Y1; Motor C uses Y2;Interval time is set with T0 K6000; total stop time using T1 + T2 + T3 is 7200 seconds;2.
