I used a full-blown plc for about 2 years to run my tank in partnership with a aqua medic at control. I have now replaced it with the p3 and touch with 2 pab6 power bars. Very cool: how ever I got use to the easy way of programming the logic on the plc with the drag and drop (ladder) programming. Also it had the option of simulating the program on the pc before you wrote it to the controller.

On the p3 I find it very difficult to program the logic or to understand what the result would be.

Thus my question is there a more logical way of programming the p3 like ladder programming and to test(simulate) the program before you write it to the p3
