PLC Program Flow Diagram Help

Hi Everyone,

Does anyone know of a good resource describing how to generate a program flow diagram that can easily be interpreted into ladder logic? The group that I'm working with is requiring a flow diagram and I have never done this before (I have always just jumped into the rung logic). In particular, a flow diagram describing an rss file would be extremely useful.

Thanks
