Expert Solution & Answer
Chapter 15.6, Problem 3P
Explanation of Solution
Changes made on given FBD
- To change the on-delay time of the given program, change the timer from 10 seconds to 1 minute, the user should change the value of the input reference connected to the “PRE” pin to “60000”.
- Reasons:
- In the FBD program, the value of time base for preset (PRE) is always 1 msec.
- From the given question, the value of PRE should be changed from 10 seconds to 1 minute...
