Posted 13 Oct 2015 (edited) My tip is that you forget about trying to 'convert' as most Ladder Logic is poorly writen and mostly diagnostics which is better put into a separate piece of the FBD. Build the Function Block Diagram from the begginning starting with a good sequence of operations for each part or section of the machine or process you are working with and for the 'control' only. Once the control is done then add the diagnostics using parallel FBDs whenever possible, this will greatly increase all troubleshooting in the future.
