Hello again,
Still working on my tank mixing project between breakdowns and maintenance!
It would be really helpfull if any of you fancy looking at what I have so far (BTW I still class myself as a novice programmer compared to the regulars on here)
For the fill sequence (x12!)I will be using 1 ladder for each tank; the steps will be controlled by an integer count.
The program is written for EASY diagnostics, and not for compactness! I appreciate that much of this could be done using indorect adressing etc, but I have plenty of space so want it to beeasy to follow!
It is still work in progress, and I know some features (power failure recovery etc) still need to be nailed.
Here is the original concept:

I have attatched the program so far, plus a pdf with a scan of a rough flow chart for filling one of the tanks, and a rough flow chart for one section of the fill sequence. Alos on the pdf is the tank valve layout.
Any comments and suggestions welcomed!
Edit - scans were too big, but time for home now; will add tonight!
