 Lab Activity Programm able Logic Contro TECH 425 PLC Introduction 50 points o BJECTIVES 1. To write a program that simulates road construction direction signal MATERIALS NEEDED DirectSOFT32 manual PLC textbook INSTRUCTIONS Utilize a counter that counts up every second, activated by a timer, for each shift register 2 shift bit functions a c to make 2 LEDs light in sequential order one second apart from one another, emulating a road construction direction signal a. shifting from top to bottom b. shifting from bottom to top c. shifting inward or outward (choose one) 3. Make each function a c repeat and run independent of each other 4 Add function that will produce the total number of times a and b occurred 5. Add all comments and nicknames along with an end statement. 6. The lab instructor will sign the lab sheet upon completion 7. write another (separate) program using a drum sequencer that makes the LEDs performthe functions above
