Question: Write a control ladder logic program for the following conditions, and test it in LogixPro: (50 points) Output SOL C is energized at the time
Write a control ladder logic program for the following conditions, and test it in LogixPro: (50 points)
Output SOL C is energized at the time the MCR instruction makes a true-to-false transition. SOL C remains energized,
The fenced zone controlled by the MCR instructions is for the following input and output:
o Limit switch LS1 controls the output Solenoid A.
o Limit switch LS2 controls the output Solenoid B.
o Limit switch LS3 controls the output Solenoid C.
o Limit switch LS4 controls the output Solenoid D.
Manual Automatic switch is the conditional instruction that controls the MCR zone,
The latch and unlatch instructions would be classified as retentive outputs,
A temperature sensor activates an alarm system when the temperature goes beyond the set value.
