I am learning Rslogix on my own when free time is available at home and have created several simple programs. My question now, is how to change the value of a TON preset value in a program using inputs to increase and decrease the value. Any help is greatly appreciated.

Thanks

The Preset of a timer - for example T4:10.PRE for timer T4:10 - can be the destination of any MOV or mathematical operations.

The instruction - ADD 1 T4:10.PRE T4:10.PRE - would add 1 to the current value of the preset.

Just make sure that you include a limiter to make sure that the preset cannot go negative.

LES Timer.PRE 0 MOV SomeSafeValue Timer.PRE.

Negative values in the preset will fault most processors.
