PLC Program Flow Diagram Help

[CorreyC]

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

Personal opinion: flow charts are a great way of documenting completed code for training and furture de-bugging. It is a cumbersome way to create logic at the inception of a program. I much prefer using "pseudo code" which is essentially an outline form text description of the various functions and aspects of the program.
