Question regarding the protection device input

Assignment Help Electrical Engineering
Reference no: EM131085138

A hoist is fitted with a protective device which operates at a height of 2.0 m. Above 2.0 m the protective device inputs logic 00 to the controlling microprocessor system. As the hoist descends towards the 2.0 m limit, the input changes to logic 01. Should the hoist descend past the 2.0 m limit, the input returns to logic 00. Write a program that continually checks the state of the input signal at 001 and which outputs the byte 20 (which stops the hoist) at 00 after the protection device input has changed from 00 to 01 and back to 00.
