Cycle counter RSLogix 500 ML 1400

[bearsgone 1]

Hello I am trying to set up a counter that would go through two zones in non stop cycle. On count 1 zone 1, on count 2 zone 2. On count 3 restart counter and start with count 1 zone 1. Presently it gets stuck on zone 1 (B3:5/0) Do not know where is the fault in the logic? Thanks in advance

bearsgone, come on think about rung 11 for a minute, if your count is EQU to one then the rung is true. When it passes count one then it will not be true and the add function can not happen there for the third rung will never be true. why are you adding the two int files, a counter is to count some maybe you should try and use the counter in the third rung ie if counter C5:0.ACC is EQU to TWO then do this. the next rung will maybe be, when counter C5:0.ACC is EQU to three then res the counter and MOV 1 to C5:0.ACC. This will restart the sequence of logic.
