How do you chage K value in timer?

Hi guys, I am use to AB software and have always been able to change the set point of a timer via a touch screen. How is this accomplished with a q series PLC??? I can't find anyway of writing to change the set point of a timer from the HMI. Seems like it can only be set while online.

If it's a "K" value in the program it's a constant - that's why you cannot change it from the HMI. You have to replace the constant with some sort of data e.g. D1000 which are then referred to in the HMI.

Ok. So instead of saying T14 K160 would I create a timer and say T14 D150 for example?

You got it.

Nice. I tried it when I got to work and that's all I had to do. Thanks guys for pointing me in the right direction.
