Internet PLC Forum

Hi. Can anybody advise where I can find some typical plc ladder logic diagram examples ? I have a college project (Two tanks filled by pumps using level switches, then flow into mixing tank, timed agitator, automated outlet valves etc) which requires to be (eventually) programmed with TriLOGI.

I have a rough schematic drawn up but, would love to see an example of an actual detailed plc ladder diagram incorporating (power) starts, stops etc through to the end of the program.

Thanks.
