Write a program to implement the process illustrated in Figure 839 An upcounter must be programmed as part of a batch counting operation to sort parts automatically for quality control The counter

Write a program to implement the process illustrated in Figure 8-39. An up-counter must be programmed as part of a batch-counting operation to sort parts automatically for quality control. The counter is installed to divert 1 part out of every 1000 for quality control or inspection purposes. The circuit operates as follows:

• A start/stop pushbutton station is used to turn the conveyor motor on and off.

• A proximity sensor counts the parts as they pass by on the conveyor.

• When a count of 1000 is reached, the counter's output activates the gate solenoid, diverting the part to the inspection line.

• The gate solenoid is energized for 2 s, which allows enough time for the part to continue to the quality control line.

• The gate returns to its normal position when the 2-s time period ends.

• The counter resets to a and continues to accumulate counts.

• A reset pushbutton is provided to reset the counter manually.
