Please provide a ladder rug logic for the following exercise (using OMRON software)
A vessel is being filled with raw material. The application requires an alarm to sound when the supply system leaks 5 lbs. more of raw material after a preset weight of 500 lbs. has been reached.
Step 1: When the start button is pressed the fill solenoid and filling indicator lamp are turned on and raw material is allow to flow into the vessel.
Step 2:The vessel has its weight continuously monitor by the PLC program as it fills
(weight is store in D0)
When the weight reaches 500 Lbs. the fill solenoid is de-energized and the flow is cut off.
Step 3: At the same time the filling pilot light indicator is turned off and the full pilot light indicator is turned on.
Step 4: Should the fill solenoid leak 5lbs. more of raw material into the vessel the alarm will energize and stay energized until the flow level is the reduced below the 5 lbs. overflow limit.( no need to implement the logic to eliminate overflow level)
Thank you
