If a Start-button is pressed, the piston rod of the cylinder move until reaching the
sensor for the front/back position depending on the hardware and then move back
to starting condition automatically. After starting 5 times, the Start-light must be on
and the piston rod can not move again. Set the counter by pressing the Reset-button
once.
Information
Use FC1 to edit the programs. Please use symbol adresses. The programming
language for FC1 should be FBD, for OB1 STL. Use Counter 1 for this project.
Instructor: Explain the differences to count up or count down from the output point
of view. Explain the function of the edge memory. Explain why it´s better to use it
for this project à some contacts shetter or bounce à the counting would not be
correct.
Planning
Please plan your project step by step first within the team. Check out the function of
all counters as shown for the timers in the Project 2.9 and choose the right counter
for your project. Edit on a sheet of paper first.
The time to finish this project should be around 1,5 hour including theory and print
