Smart Component training exercises

sturner

We are noticing random behaviour when executing the simulation on the Lathe exercise in the RS5.13 training courseware.

 

Parts on the conveyor seem to float off the end at times.

The lathe door floats out of the lathe.

the lathe chuck jaws sometimes work then give up.

 

The RAPID has been checked many times and the smart component I/O connections have also been checked.

Could the performace of our laptops cause timing problems when relying on PulseDO in RAPID?

Anyone else getting similar problems?

Hi Sturner,

I made that exercise, so I will take a look at it and see if I can improve the Smart Components.

Laptops with bad performance can cause problems when Smart Components are used. You should also make sure that you have set Virtual Time to Time Slice.

I found out that if there is parts from previos simulation generated with the copy function in SC i faced the same problem. be sure the all parts generated from "copy part" in SC is deleted before new simulation. Somtimes they are unviseble. See your browser for non deleted parts after simulation.

see my simulation on video on RS forum or on my website under robotsimulation. sorry the site is on danish but can't also bee found on youtube. google cadalysator on youtube

Still getting problems with exercise.

In 5.2.4 step 3...

It suggests to deselect the Active Task in the simulation

 

step4... Select the simulation start Scenario and deactivate VC from the simulated objects.

 

step 5... Go to offline tab and switch controller to Auto

step 6 put PP to main and start program in Program Editor.

 

Program will not start when VC deselected... and will not play the program again in the editor until controller is restarted.

Workpieces do not feed down conveyor if the VC is deselected.

 

Cany you explain why it suggest to deselect the VC in the simulation setup and not to enable again?

The simulation works when you start the simualtion for the Simualtion Play button then start the program from the editor.

 

Should I restore the simulation state that was setup in the station logic.

We appear to get many parts foating off the end of the conveyor and very very slow robot motion.

Lenovo T61P laptop appears to struggle to cope with this simulation.

If you not deselect the VC from the simulation, the program execution will start automatically when you press simulation play, and it will not be possible to start and stop the execution from the rapid editor (as you would like to do when you debug your rapid code).

If you do as it's said in point 5.2.4 point 4, the station will be restored to the simulation state automatically when you press simulation play. As Klaus said above it's important that you not have any old copies generated from the SC_Infeeder left in the station when you save the state.

The Lenovo T61P is probably not a suitable PC for this exercise, or for other similar RobotStudio stations/simulations.
