Thanks for the update. I too just received my 462 and have been rumblin', bumblin' and stumblin' through processes, states, set points, exits the past couple of days. Temp sensors are back ordered so I can't do wet "dry runs" on nearly ready brew stand and control box to see actual results of programming. Haven't ventured near ladder-logic at all, not a clue - yet.
4.0 sounds promising. Single page to view your entire recipe protocol would greatly simplify things. I'm still getting hung up setting variables for each state in a process without goofing up another state, and coming to the realization that "pause" my be a frequently used state.
