thanks for the drawing Lancie1. Question? I just scrolled up to the top of the page & clicked on the "free PLC simulator". It took me to another Log in. I used my log in name & pass word for this site to no avail. Did it not let me in because I am a free member or is the link to a completely different site? To me it looked like the same site as this site. Aqain, thanks for help n suggestions.
